Is the Ergodyne GloWear 8370 the right hi-vis shirt for road and utility crews who want Class 3 visibility without sweating through a vest-over-shirt setup?

Short answer: For warm-weather road and utility crews who need built-in Class 3 coverage instead of a vest layered over a tee, the GloWear 8370 is a strong pick — the performance moisture-wicking fabric manages sweat better than the standard-fabric 8368, and the full-lime build keeps you compliant on its own. If you run hot or want a more professional look, weigh the short-sleeve 8367 or the black-front 8371BK; browse the full range in hi-vis shirts or our best hi-vis shirts guide.

Ergodyne GloWear 8370 Class 3 Hi-Vis Long Sleeve Performance Shirt Review (2026)

The GloWear 8370 sits at the top of the conspicuity scale: it is certified to ANSI/ISEA 107-2020 as a **Type R, Class 3** garment, the highest standalone classification and the tier required for workers exposed to high-speed traffic, low-light shifts, and full-motion roadway tasks. Where a Class 2 shirt clears the bar for warehouses, parking, flagging, and roadway work under roughly 25 mph, Class 3 adds the larger fluorescent background area plus sleeve retroreflective coverage that lets a driver read your full body and limbs against a complex visual background — the distinction our Class 2 vs Class 3 explainer walks through. Type R means it is built for roadway and public-access right-of-way work governed by OSHA and MUTCD, not the off-road Type O category. Because the 8370 carries that coverage in the garment itself, it removes the layered vest-over-shirt compromise that road and highway crews otherwise live with; see the broader high-visibility apparel lineup for how shirts fit alongside vests and jackets.

Editorial verdict — 4.3/5
For the price of a quality work shirt you get genuine Type R Class 3 compliance plus performance moisture management, which is a fair trade if you would otherwise sweat through a tee under a vest — just expect more thermal load than a mesh vest and a plain all-lime look.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

Who it is for

• Road construction and highway maintenance crews who need built-in Class 3 visibility for high-speed traffic zones — see the best hi-vis shirts guide
• Utility lineworkers and infrastructure crews who run hot and want moisture-wicking comfort over a vest-and-tee stack, browseable in hi-vis shirts
• DOT and surveyor field personnel who prefer a garment over a vest but still carry tools — pair with the six-pocket 8346Z surveyor vest when storage matters
• Flaggers and night-shift crews whose OSHA hi-vis requirements push them to Class 3 sleeve coverage rather than Class 2
• Warm-climate crews who want long-sleeve UV protection without dropping to the short-sleeve 8367
• Programs standardizing on uniform all-lime appearance rather than the black-front 8371BK

What the Ergodyne GloWear 8370 does well

Top-tier Class 3 conspicuity in a shirt

The 8370 delivers full Type R Class 3 coverage — the maximum standalone ANSI rating — with fluorescent lime across the front, back, and sleeves plus retroreflective bands, so drivers read your full silhouette in high-speed and low-light conditions the way our Class 2 vs Class 3 guide describes.

Performance fabric earns its name

Unlike the standard-fabric 8368, the 8370 uses moisture-wicking performance fabric built to move sweat during sustained physical labor — the reason to pay up over a basic Class 3 long-sleeve when shifts are long and hot.

Compliant on its own

Because the garment itself carries Class 3 coverage, it eliminates the vest-over-tee compromise; you stay OSHA-compliant without a second layer, which is cleaner for active work than a vest that rides up. Compare against the vest path in ANSI class 3 vests.

Long-sleeve UV coverage

The full-length lime sleeves add sun protection for all-day outdoor crews — an advantage over short-sleeve hi-vis shirts and over a Class 2 vest worn over bare arms, and the trade our how to choose a hi-vis vest reference frames against vest options.

Where the Ergodyne GloWear 8370 falls short

Warmer than a mesh vest

Class 3 long-sleeve coverage means more fabric on your body than a breathable mesh Class 2 vest, so in peak summer heat the 8370 runs warmer even with moisture-wicking fabric — crews who need maximum airflow may prefer a mesh vest plus tee or the short-sleeve 8367.

Plain all-lime styling

The uniform lime build is purely functional; for supervisors and inspectors who want a more tailored, professional look the black-front 8371BK reads cleaner in client-facing settings while keeping Class 3.

Harder to keep compliant long-term

A shirt that fades, shrinks, or wears at the cuffs is harder to keep within ANSI background-area specs than a swap-out vest you can simply replace — see how to choose a hi-vis vest for the durability trade-off between garments and vests.

Single colorway

This exact model is all-lime only; crews on orange-standard programs will need a different SKU, and there is no orange 8370 listed alongside it in our hi-vis shirts range.

When to step up from the Ergodyne GloWear 8370

If you want the same performance fabric and Class 3 rating but a more professional appearance, step up to the black-front 8371BK — it shares the 8370's moisture-wicking construction but adds a black accent that hides grime and reads cleaner in client-facing roles. If you need to carry tools and instruments rather than just stay visible, a Class 3 garment will not store gear, so pair the shirt with the six-pocket 8346Z surveyor vest or shop the broader ANSI class 3 vests and best hi-vis shirts guide to balance visibility, storage, and cost.

Category context

Choosing between Class 2 and Class 3 comes down to traffic speed and light: Class 2 covers parking, warehousing, flagging, and roadway work in lower-speed environments, while Class 3 is mandated where vehicles move fast, light is poor, or workers are in full motion — the threshold our Class 2 vs Class 3 explainer and the ANSI/ISEA 107-2020 guide detail, and that OSHA's hi-vis requirements enforce. The other axis is garment format: a vest is the most breathable and easiest to swap, a shirt like the 8370 builds visibility into the layer you already wear and adds sleeve coverage, and a jacket adds weather protection for cold or wet shifts. Color is a third consideration — both lime and orange are ANSI-recognized, and our hi-vis colors explained and hi-vis color meaning references cover when crews standardize on each. The 8370's all-lime, long-sleeve, performance-fabric format is the sweet spot for crews who want Class 3 worn as a shirt rather than a vest over a tee.

Total cost of ownership

Total cost of ownership on a hi-vis shirt turns on wash cycles and retroreflective tape life: every laundering and every hour of UV exposure slowly fades the fluorescent background and dulls the reflective bands, and once either drops below ANSI's specified area or brightness the garment is no longer Class 3 compliant — a point our how to choose a hi-vis vest reference stresses. The 8370's performance fabric is built for repeated wear and wash, but unlike a vest you cannot simply hand off a faded shirt to the next worker, so plan a replacement cadence and inspect cuffs, seams, and tape after heavy use. Compared with the cheaper standard-fabric 8368, the performance fabric costs more up front but tends to hold up better under sweat and movement; for high-turnover or visitor programs a swap-out Class 2 vest or Class 3 vest may carry lower lifetime cost. Weigh per-garment price against expected wear life and how often your crews launder, using the best hi-vis shirts guide to benchmark.

Final verdict

Buy the GloWear 8370 if you are a road, highway, or utility crew member who needs genuine Type R Class 3 visibility worn as a comfortable long-sleeve shirt rather than a vest over a tee, and you value moisture-wicking fabric for long warm-weather shifts — it is one of the better all-lime performance options in our hi-vis shirts range. If you run hot in peak summer, drop to the short-sleeve 8367 or a breathable Class 3 vest; if you want a more professional look, choose the black-front 8371BK; and if your work zone is lower-speed, the Class 2 8284 saves money while staying compliant. Confirm your required class first with our OSHA hi-vis and Class 2 vs Class 3 references.

Ergodyne GloWear 8370 FAQ

Is the Ergodyne GloWear 8370 ANSI Class 2 or Class 3?

The 8370 is certified to ANSI/ISEA 107-2020 as a Type R, Class 3 garment — the highest standalone conspicuity tier. That means it is built for high-speed traffic, low-light, and full-motion roadway work rather than the lower-speed environments a Class 2 shirt covers. Our Class 2 vs Class 3 guide explains the distinction.

What does Type R mean on the 8370?

Type R designates roadway and public-access right-of-way garments governed by OSHA and MUTCD, as opposed to Type O for off-road industrial use. The 8370 is a Type R shirt, so it is appropriate for crews exposed to public traffic. The ANSI/ISEA 107-2020 guide covers Type R versus Type O in full.

How is the 8370 different from the GloWear 8368?

Both are Type R Class 3 all-lime long-sleeve shirts, but the 8370 uses performance moisture-wicking fabric while the 8368 uses standard hi-vis fabric at a lower price. Choose the 8370 if sweat management during sustained labor matters; choose the 8368 to minimize cost. Both are compared in our best hi-vis shirts guide.

Should I pick the 8370 or the short-sleeve 8367?

The 8370 long sleeve adds UV arm coverage and is better for cooler or sun-exposed shifts, while the 8367 short sleeve ventilates better in peak summer heat. Both carry the same Type R Class 3 rating, so it is purely a thermal-comfort trade. See hi-vis shirts for the full set.

Can the 8370 replace a hi-vis vest for compliance?

Yes — because the shirt itself carries full Class 3 coverage, it is compliant on its own and does not need a vest layered over it. That removes the vest-over-tee compromise active crews otherwise deal with. If you also need to carry tools, pair it with a pocketed vest like the 8346Z surveyor vest.

Does long-sleeve Class 3 run hot?

Compared with a breathable mesh Class 2 vest, yes — there is more fabric on your body. The 8370's performance moisture-wicking fabric mitigates this, but crews in extreme heat may prefer the short-sleeve 8367 or a mesh vest plus tee. Weigh airflow against the UV coverage long sleeves provide.

Is the 8370 available in orange?

This exact model is listed in all-lime only. Crews on orange-standard programs will need a different SKU; browse the hi-vis shirts collection for orange Class 2 options like the 8286BKO. Both lime and orange are ANSI-recognized — see hi-vis colors explained.

Does OSHA require Class 3 for my crew?

OSHA references ANSI/ISEA 107 and MUTCD; whether you need Class 3 depends on traffic speed, lighting, and your task. High-speed traffic, night work, and full-motion roadway tasks generally call for Class 3, while lower-speed zones may allow Class 2. Confirm with our when does OSHA require high visibility reference before specifying.

What is the difference between the 8370 and the black-front 8371BK?

They share the same performance moisture-wicking fabric and Type R Class 3 rating; the 8371BK adds a black front accent for a more professional look and better grime concealment, while the 8370 is uniform all-lime. Programs that specify maximum fluorescent coverage favor the 8370; client-facing roles often prefer the 8371BK.

How do I keep the 8370 ANSI-compliant over time?

Inspect the fluorescent background and retroreflective tape regularly — fading from UV and repeated washing can drop a garment below Class 3 specs. Unlike a swap-out vest, a worn shirt is harder to keep compliant, so plan a replacement cadence. Our how to choose a hi-vis vest reference covers tape and background longevity.

Is a Class 3 shirt better than a Class 3 vest?

Neither is universally better — a vest is more breathable and easy to swap between workers, while a shirt like the 8370 builds visibility into the layer you wear and adds sleeve coverage for full-body conspicuity. For storage and turnover, a vest from ANSI class 3 vests may suit better; for integrated comfort, the shirt wins.

Will the 8370 work for surveyors and field crews?

It provides Class 3 visibility but no pockets, so surveyors who carry instruments should pair it with a pocketed vest such as the 8346Z surveyor vest. For pure conspicuity with long-sleeve UV protection, the 8370 works well. See the best hi-vis shirts guide for field-crew picks.

Why choose lime over orange for the 8370?

Both fluorescent lime-yellow and orange are ANSI-recognized hi-vis colors; many programs standardize on lime for maximum daytime contrast against typical roadway backgrounds. The 8370 ships all-lime. Our hi-vis color meaning and hi-vis colors explained references explain when crews pick each.

Is the performance fabric worth the price over standard fabric?

If your crews work long, hot shifts, the moisture-wicking performance fabric of the 8370 manages sweat far better than the standard-fabric 8368 and tends to hold up under movement. For occasional wear or tight budgets, the standard-fabric 8368 saves money while keeping the same Class 3 rating.

What should I wear if I also need weather protection?

A shirt does not block rain or cold; for wet or cold roadway shifts step up to a hi-vis jacket such as the waterproof TICONN 1735 bomber or a fleece Class 3 hoodie. The 8370 is best as a warm-weather base layer that is compliant on its own.

Does the 8370 cover Class 2 requirements too?

Yes — a Class 3 garment exceeds Class 2 minimums, so the 8370 is acceptable anywhere Class 2 is required as well as in Class 3 environments. If your work is consistently lower-speed, though, a Class 2 long-sleeve shirt costs less. Confirm your required class with the Class 2 vs Class 3 guide.

How does the 8370 compare to a hi-vis hoodie for cold weather?

The 8370 is a single-layer performance shirt with no insulation, so for cold shifts a fleece-lined Class 3 hoodie like the TICONN 1903 or TICONN 1479 keeps you warmer. Use the 8370 for warm seasons and layer up with a hoodie or jacket when temperatures drop.
