Bullard C33 Full Brim Hard Hat Review: Honest Guide for Construction, Utility & Outdoor Crews
Is the Bullard C33 the right full-brim hard hat for your jobsite?
Short answer: Yes — for crews who want an American-made, all-around full-brim shell with a smooth 6-point ratchet and a wide accessory ecosystem, the Bullard C33 is one of the easiest Type I / Class E full brims to recommend in the $25–$42 range. It earns a 4.6/5 from our desk on the strength of its made-in-USA HDPE shell, comfortable suspension, and broad slot-compatible accessory support. It is the right pick when you want all-day comfort and 360-degree sun and rain shedding; it is the wrong pick if you need a chinstrap-retained climbing helmet (look at the Milwaukee BOLT review) or a high-heat shell for steel and foundry work, where the phenolic MSA Skullgard Full-Brim is the better tool.
The Bullard C33 sits in the middle of a crowded full-brim field. On wcsafety.com alone it competes with the MSA V-Gard Full-Brim, the Fibre-Metal E1RW Full Brim, the budget-priced Pyramex Ridgeline Full Brim, and the trade-favorite Klein Tools Full Brim. What sets the C33 apart is the combination of a genuinely comfortable suspension, Bullard's long accessory history, and the fact that the shell is molded in the USA — a real consideration for crews on federally funded or Buy American Act jobs.
This review is a buyer's-guide analysis, not a destructive-test lab report. We ground the assessment in the ANSI/ISEA Z89.1 standard the C33 is certified to, Bullard's published technical documentation, and head-to-head comparison against the full-brim shells we actually stock and sell. Where the C33 wins, we say so; where a sibling like the spacious-shell Bullard C34 Full Brim or a competitor is the smarter buy, we say that too.
If you are still deciding between a cap style and a full brim, or between HDPE and a Type II shell, start with our Hard Hat Selection: Complete Buyer's Guide (2026) and our Best Hard Hats for Construction: 8 Top Picks (2026 Buyer's Guide), then come back here for the C33-specific breakdown.
Editorial verdict — 4.6 / 5
The Bullard C33 is the value-comfort sweet spot of the made-in-USA full-brim category: a Type I, Class E HDPE shell with a smooth 6-point ratchet suspension, full 360-degree sun and rain protection, and one of the deepest accessory ecosystems of any hard hat we carry. It loses a half-step only because it is non-vented (no Class C option in this model), the brim is wider to manage in tight overhead spaces, and premium competitors edge it on suspension refinement. For general construction, utilities, inspection, and outdoor trades, it is a buy.

What we like
- Made in the USA — HDPE shell molded domestically; supports Buy American Act and Build America sourcing.
- Smooth 6-point ratchet — fine micro-adjustment and even crown load distribution for all-day wear.
- Full 360-degree brim — sheds sun, rain, and debris off the neck, ears, and face better than a cap style.
- Deep accessory ecosystem — universal-slot compatible with cap-mount ear muffs, face shields, and winter liners.
- Type I / Class E rated — top-impact protection plus 20,000-volt dielectric rating for electrical exposure.
- Fair price — $25–$42 puts a USA-made full brim within budget of most crews.
Where it gives ground
- Non-vented in this model — no Class C airflow option; runs warmer than a vented cap style in summer heat.
- Wide brim in tight spaces — the 360-degree brim can catch on ductwork, scaffolding, and confined overheads.
- No integrated chinstrap — not an ANSI Type II / EN 12492 climbing helmet; needs an add-on strap for work at height.
- Suspension refinement — premium shells edge it on nape-pad plushness and ratchet feel for the money.
- HDPE heat ceiling — not for radiant-heat or molten-metal work; that is phenolic Skullgard territory.
Who the Bullard C33 is for
The C33 is a generalist full brim that fits the widest slice of outdoor and industrial trades. Buy it if you are:
- General construction and site crews who want all-day sun and rain protection over a cap style.
- Utility, lineman-adjacent, and electrical trades needing the Class E 20,000-volt dielectric rating (verify against your task voltage).
- Inspectors, surveyors, and field supervisors who spend hours outdoors and want the brim's glare and rain control.
- Procurement teams on Buy American Act / Build America jobs who need a documented made-in-USA shell.
- Crews standardizing on one accessory platform — the C33 shares the Bullard slot system with its cap-style siblings.

What the Bullard C33 does well
Made-in-USA HDPE shell with documented sourcing
The headline differentiator is domestic manufacturing. The Bullard C33 shell is molded in the USA from high-density polyethylene, which matters on federally funded infrastructure work governed by the Buy American Act and the Build America, Buy America provisions. Several competing full brims are imported; if your project requires documented domestic content, the C33 (alongside the made-in-USA Bullard S61 Cap Style and Bullard S62 Vented Cap Style) clears a procurement hurdle that imports cannot.
Genuinely comfortable 6-point ratchet suspension
Six suspension points spread the shell's weight across more of the crown than a 4-point system, which reduces hot-spotting on long shifts. The ratchet knob gives fine, gloved-hand micro-adjustment so the fit stays put through a day of looking up and bending over. For crews coming off a cheap 4-point pin-lock hat, the comfort jump is the first thing they notice — and comfort is the single biggest driver of whether a hard hat actually stays on the head.
Full 360-degree brim that earns its keep outdoors
The full brim is the whole point of the category. Unlike a cap style, the C33's continuous brim sheds rain off the back of the neck, keeps sun off the ears and neck, and drips water away from the collar instead of down it. For anyone working outdoors all day — roadway, utility, survey, inspection — that 360-degree coverage is a measurable daily comfort and sun-exposure win. We cover the cap-vs-full-brim tradeoff in depth in the Hard Hat Selection: Complete Buyer's Guide (2026).
One of the deepest accessory ecosystems we stock
Bullard has been making head protection for over a century, and the accessory support shows. The C33's universal slots accept cap-mount ear muffs, slot-mounted face shields, and cold-weather winter liners. Standardizing a crew on the C33 means one accessory platform across the kit — and because the slots are shared with Bullard's cap-style hats, mixed crews can pool accessories.
Type I / Class E protection at a fair price
The C33 is certified to ANSI/ISEA Z89.1 as a Type I (top-impact) hat with a Class E electrical rating, meaning it is tested to withstand up to 20,000 volts. That is the protection profile most general-industry and construction buyers actually need, and getting it in a USA-made shell for $25–$42 is strong value. The Klein Tools Full Brim and 3M SecureFit Full Brim hit similar ratings, but few pair them with documented domestic manufacturing at this price.
Where the Bullard C33 falls short
No vented (Class C) option in this model
The C33 is a non-vented Class E shell, which is exactly what you want around electrical hazards but works against you in summer heat. There are no crown vents to dump trapped heat, so on a hot, still day it runs warmer than a vented cap style. If your hazard assessment rules out energized exposure and heat is your enemy, the vented Bullard S62 Vented Cap Style (Class C) is the cooler choice — at the cost of giving up the dielectric rating and the full brim.
The wide brim is a liability in tight overhead work
A 360-degree brim is wonderful outdoors and a nuisance in a crawlspace. In confined overheads — ductwork, dense scaffolding, mechanical rooms, vessel entry — the brim catches on obstructions and reduces upward sightlines compared to a cap style. Crews who split their time between open-air and tight-quarters work sometimes keep a cap style like the Bullard S51 Flat Front on the truck for the indoor days.
Not a fall-protection / climbing helmet
Like every traditional full-brim hard hat, the C33 ships without an integrated chinstrap and is not certified to the ANSI Type II / EN 12492 climbing-helmet standard. For work at height where a hat could fall off — tower, leading-edge, and rope-access work — a retained safety helmet is the right tool. If that is your use case, read the Milwaukee BOLT review and the 3M SecureFit X5000 review instead of a traditional full brim.

Bullard family: C33 vs C34 vs S61 vs S62
If you have already settled on Bullard, here is how the C33 lines up against its closest in-house siblings. Differentiator rows are highlighted.
| Spec | Bullard C33 | Bullard C34 | Bullard S61 | Bullard S62 |
|---|---|---|---|---|
| Style | Full brim | Full brim | Cap style | Cap style |
| Shell material | HDPE | HDPE | HDPE | HDPE |
| Suspension | 6-pt ratchet | 6-pt ratchet | 4-pt ratchet | 4-pt ratchet |
| Electrical class | E | E | E | C (vented) |
| Vented | No | No | No | Yes |
| Shell roominess | Standard | Spacious | Standard | Standard |
| Made in USA | Yes | Yes | Yes | Yes |
| Typical price | $25–$42 | $28–$46 | $20–$34 | $22–$36 |
Decision rule — which Bullard to buy:
- Buy the Bullard C33 if you want the standard-fit, made-in-USA full brim with a comfortable 6-point ratchet for general outdoor and electrical-class work — the default pick for most buyers.
- Buy the Bullard C34 if you have a larger head, wear a thicker liner, or simply want a roomier shell — same full-brim format with extra interior space.
- Buy the Bullard S61 if you work in tight overheads and want a lower-profile cap style at a lower price, keeping the Class E rating.
- Buy the Bullard S62 if heat is your main enemy and you have ruled out energized work — the vents make it the coolest of the four, at the cost of the dielectric rating.

Compatible accessories for the Bullard C33
One of the C33's quiet strengths is its accessory support. The universal slots accept the three categories crews add most often:
- Cap-mount ear muffs — slot-mounted hearing protection clips directly into the C33's accessory rails, so workers in high-noise zones do not have to choose between a hard hat and over-the-head muffs. Browse the ear muffs collection for cap-mount-compatible options.
- Face shields — slot-mounted face shields and brackets add splash, debris, and grinding protection without a separate headgear band. See the face shields collection for compatible carriers.
- Winter liners — cold-weather liners tuck under the suspension to add ear and neck warmth for outdoor winter work, while keeping the shell's impact protection intact.
Because the slot system is shared across Bullard's cap-style and full-brim hats, a crew running a mix of C33 full brims and Bullard S61 cap styles can pool the same muffs, shields, and liners across both. That accessory portability is a real cost-of-ownership advantage when you standardize a fleet.

Category context: HDPE vs fiberglass, and why full brim
Two material families dominate hard hats. HDPE (high-density polyethylene), used in the C33 and most mainstream shells, is light, low-cost, electrically non-conductive, and easy to mold — which is why it is the default for general construction and electrical work. Phenolic fiberglass, used in the MSA Skullgard Full-Brim, tolerates far higher radiant heat and is the choice for steel mills, foundries, and smelting. The tradeoff: fiberglass is heavier and pricier. For anything short of high-heat work, HDPE like the C33 is the right material; reach for phenolic only when radiant heat is the defining hazard.
On the full-brim-versus-cap question, the full brim's advantage is 360-degree coverage: sun off the neck and ears, rain off the back of the collar, and debris deflected away from the face on all sides. The cost is bulk in tight spaces. For outdoor trades — utilities, roadway, survey, inspection — the brim pays for itself in daily comfort and sun protection, which is exactly the C33's wheelhouse. Our Best Hard Hats for Construction: 8 Top Picks (2026 Buyer's Guide) walks through where each style wins.
Total cost of ownership
The C33's base price of $25–$42 carries a modest made-in-USA premium over the cheapest imported full brims (the Pyramex Ridgeline Full Brim typically undercuts it), but the domestic-sourcing documentation is the value you are buying — and on Buy American Act jobs, the imported alternative is not even eligible, so the comparison is moot.
Replacement cadence is the bigger cost driver. ANSI/ISEA Z89.1 and most safety programs treat the shell as having roughly a 5-year service life from the date of manufacture (molded into the shell) and the suspension as a shorter-lived wear item, typically replaced every 12 months or sooner if damaged. Budget for replacement suspensions over the shell's life rather than tossing the whole hat. Any hat that takes a real impact is retired immediately, regardless of age.
Add the accessory spend you actually need — cap-mount ear muffs, slot face shields, winter liners — and because those accessories carry over to Bullard's cap-style hats, standardizing the fleet on the Bullard slot system lowers the per-worker accessory cost across a mixed crew. That portability is the C33's strongest total-cost argument.
Final verdict on the Bullard C33
4.6 / 5. The Bullard C33 is the made-in-USA full brim we recommend first for general construction, utilities, inspection, and outdoor trades. It nails the things that matter day to day — a comfortable 6-point ratchet, full 360-degree protection, a deep accessory ecosystem, and Class E electrical safety — at a fair $25–$42 with documented domestic sourcing. It is held back only by being non-vented, by the wide brim's awkwardness in tight overheads, and by premium rivals that edge it on suspension polish.
- Buy the C33 if you want a comfortable, USA-made, all-around full brim for outdoor and electrical-class work.
- Buy the Bullard C34 if you need a roomier shell.
- Buy the Bullard S62 if heat beats electrical risk and you want vents.
- Buy the MSA Skullgard Full-Brim if you face radiant or molten-metal heat that HDPE cannot take.

Bullard C33 — frequently asked questions
Is the Bullard C33 made in the USA?
Yes. The Bullard C33 shell is molded in the USA from high-density polyethylene, which makes it eligible for Buy American Act and Build America, Buy America procurement where many imported full brims are not. Its made-in-USA siblings include the Bullard S61 and Bullard S62. Always keep the manufacturer documentation on file for compliance audits.
What ANSI class and type is the Bullard C33?
The C33 is certified to ANSI/ISEA Z89.1 as a Type I hat (top-impact protection) with a Class E electrical rating, tested to withstand up to 20,000 volts. Type I covers the vertical-impact hazard most general-industry and construction sites face; for lateral-impact protection you need a Type II safety helmet instead. Confirm the exact certification on the Bullard C33 product page.
Bullard C33 vs Bullard C34 — which should I buy?
Both are made-in-USA HDPE full brims with 6-point ratchets and the Class E rating; the difference is interior room. Buy the Bullard C33 for a standard fit, and step up to the Bullard C34 if you have a larger head, wear a thick liner, or simply prefer a roomier shell. Fit and comfort drive compliance, so size to the head, not the spec sheet.
Bullard C33 vs MSA V-Gard full brim — what's the difference?
Both are mainstream HDPE full brims at a similar price. The MSA V-Gard Full-Brim is prized for its Fas-Trac III suspension and brand ubiquity, while the Bullard C33 leads on documented made-in-USA sourcing. If your site already standardizes on MSA accessories, the V-Gard slots in cleanly; if domestic content or the Bullard accessory ecosystem matters more, take the C33.
Is the Bullard C33 vented?
No. The C33 is a non-vented shell, which is required for its Class E electrical rating — vents would compromise the dielectric protection. If heat is your primary concern and you have ruled out energized work, the vented Class C Bullard S62 runs cooler, but it trades away both the dielectric rating and the full brim.
Can I use the Bullard C33 for electrical work?
The C33's Class E rating means it is tested to 20,000 volts and is appropriate for many electrical-exposure tasks, but the hard hat alone is not a complete electrical-safety solution. Match it to your site's arc-flash and shock risk assessment and your full PPE program. For dedicated electrical-trade crews, the Klein Tools Full Brim is a common alternative in the same class.
How long does a Bullard C33 last before replacement?
Most safety programs follow ANSI/ISEA Z89.1 guidance: roughly a 5-year shell service life from the molded date of manufacture, with the suspension replaced about every 12 months as a wear item. Retire the hat immediately after any significant impact, or sooner if you see cracks, chalking, or UV degradation. Buying replacement suspensions is far cheaper than replacing whole shells over the hat's life.
What accessories are compatible with the Bullard C33?
The C33's universal slots accept cap-mount ear muffs, slot-mounted face shields, and cold-weather winter liners. Because the slot system is shared with Bullard cap-style hats like the Bullard S51, a mixed crew can pool accessories across both styles.
Is a full-brim hard hat better than a cap style?
It depends on the work. A full brim like the C33 gives 360-degree sun, rain, and debris protection that a cap style cannot, which is a clear win for outdoor trades. A cap style is lower-profile and better in tight overheads. Crews who split between open-air and confined work often keep both — the C33 for outdoors and a Bullard S61 for indoors. Our Hard Hat Selection: Complete Buyer's Guide (2026) breaks down the tradeoff.
Does the Bullard C33 come with a chinstrap?
No. Like traditional full-brim hard hats, the C33 ships without an integrated chinstrap and is not certified to the ANSI Type II / EN 12492 climbing-helmet standard. For work at height where retention matters, choose a safety helmet instead — see the Milwaukee BOLT review and the 3M SecureFit X5000 review.
Bullard C33 vs Fibre-Metal E1RW — which has the better suspension?
The Fibre-Metal E1RW Full Brim uses an 8-point suspension that spreads crown load across more contact points than the C33's 6-point system, which some heavy-industrial wearers prefer for marathon shifts. The Bullard C33 counters with documented made-in-USA sourcing and a deep accessory ecosystem. If raw load distribution is your priority, try the E1RW; if domestic content and accessory breadth matter more, take the C33.
Is the Bullard C33 good for high-heat or foundry work?
No — HDPE is not the right material for radiant or molten-metal heat. For steel mills, foundries, and smelting, choose a phenolic fiberglass shell like the MSA Skullgard Full-Brim, which tolerates far higher temperatures. Reserve the C33 for general construction, utility, and outdoor work where heat is comfort-level, not hazard-level.
Bullard C33 vs Pyramex Ridgeline — is the price difference worth it?
The Pyramex Ridgeline Full Brim typically undercuts the C33 and offers eye-catching graphic shells, but it is an imported ABS hat. The Bullard C33 costs a little more for documented made-in-USA HDPE construction. If budget is the only driver, the Ridgeline wins; if you need domestic sourcing or are on a Buy American job, the C33 is the only eligible choice of the two.
Can I put a face shield on the Bullard C33?
Yes. The C33's accessory slots accept slot-mounted face shields and carriers for splash, debris, and grinding protection, with no separate headgear band needed. Browse compatible carriers in the face shields collection, and confirm the specific bracket fits the Bullard slot before ordering for a fleet.
Where does the Bullard C33 rank among the best construction hard hats?
The C33 is a strong all-around pick that consistently earns a spot in our recommendations for outdoor and electrical-class construction work, thanks to its made-in-USA shell, comfort, and accessory support. See exactly where it lands against the field in our Best Hard Hats for Construction: 8 Top Picks (2026 Buyer's Guide), and browse the full lineup in the full-brim hard hats collection.
Should I buy the Bullard C33 or the MSA V-Gard cap style?
They solve different problems. The Bullard C33 is a full brim for 360-degree outdoor protection; the MSA V-Gard cap style is lower-profile for tight spaces. If you work outdoors and want sun and rain coverage, take the C33; if you work in confined overheads, the cap style is easier to manage — see the planned MSA V-Gard Cap Style review for that head-to-head.
