The KleenGuard A20 coverall is a blue denim disposable protective suit built on SMS polypropylene. The A20 is Kimberly-Clark's answer to the all-shift dust suit: SMS that breathes well enough to forget you are wearing it, at a price that supports daily disposal. It is the budget rung of the KleenGuard ladder and the direct rival to 3M's 4515 and DuPont's ProShield tier. Our listing starts at $141.70, with the size run on the linked Amazon page.
Why the KleenGuard A20 Stands Out
The A20 is Kimberly-Clark's answer to the all-shift dust suit: SMS that breathes well enough to forget you are wearing it, at a price that supports daily disposal. It is the budget rung of the KleenGuard ladder and the direct rival to 3M's 4515 and DuPont's ProShield tier.
Fabric, Configuration and Protection
Breathable dry-particulate protection — nuisance dusts, dirt, and grime. Configuration: zip front with elasticized fit points, breathable sms shell. Pair it with the right respirator for drywall or silica dust — the suit stops the mess, not the inhalation hazard. Like every disposable garment, it is a single-exposure product — once contaminated, it comes off at the work boundary and enters the waste stream your standard requires.
Fit follows the disposable-coverall rule: order one size over street clothes so the suit survives crouching and reaching. Elastic interfaces seal approximately, not absolutely — for regulated work, tape the glove and boot junctions and treat the suit as one layer of a system that includes hazard-matched gloves, eye protection, and the respirator your assessment names.
Where It Falls Short
Its limits: Liquid exposure of any kind — the A20 is a dry-particulate suit; liquids start at the A40 and chemicals at the A70. No disposable coverall is a submersion garment, an arc-flash layer, or a substitute for the engineering controls that come first in the hierarchy.
Pros and Cons
Pros
- SMS polypropylene matched to a clearly defined hazard
- Zip front with elasticized fit points, breathable SMS shell
- Listed from $141.70 with live Amazon pricing
- Single-use discipline — no decontamination ambiguity
Cons
- Disposable garment — not for exposure beyond its rating or duration
- Dry-particulate only — no liquid barrier at all
Who Should Buy It
Order the KleenGuard A20 if you are drywall sanders, warehouse and maintenance crews, and clean-side manufacturing that wants breathable daily-wear dust coverage.
Who Should Skip It
Skip it for liquid exposure of any kind — the A20 is a dry-particulate suit; liquids start at the A40 and chemicals at the A70.
How It Compares
The A40 adds a microporous film for liquid splash at some cost in breathability — the A20 wins on dry, hot jobs; the A40 wins the moment liquids appear. Both sit inside the field ranked in our best disposable coveralls guide, and the disposable coveralls collection carries the full ladder from breathable particle suits to taped-seam chemical barriers.

Frequently Asked Questions
What is the KleenGuard A20 coverall rated for?
Breathable dry-particulate protection — nuisance dusts, dirt, and grime. The rating, not the price, picks the suit — match it to your hazard assessment.
What fabric is the KleenGuard A20 made of?
SMS polypropylene (KleenGuard A20). That fabric choice is the core of what it protects against and how it wears.
What sizes does the KleenGuard A20 come in?
Our listing carries one stocked configuration; the linked Amazon page lists the available sizes. Order one size over street clothes — undersized coveralls tear at the crotch and shoulders.
Is the KleenGuard A20 reusable?
No. It is a single-use garment: once worn against the hazard it was chosen for, it is doffed at the work boundary and disposed of per the governing standard.
KleenGuard A20 vs KleenGuard A40 — which should I buy?
The A40 adds a microporous film for liquid splash at some cost in breathability — the A20 wins on dry, hot jobs; the A40 wins the moment liquids appear.
Does the KleenGuard A20 have a hood?
No — it is a zip front with elasticized fit points, breathable sms shell. Choose a hooded suit when the contaminant is airborne or overhead.
What respirator should I pair with the KleenGuard A20?
The hazard that picked the suit picks the respirator: P100 filters for dusts, fibers, and mold; chemical cartridges for vapors and spray. Start with our when-do-you-need-a-respirator guide and the respiratory protection collection.
Are the seams on the KleenGuard A20 sealed?
Zip front with elasticized fit points, breathable SMS shell. Serged seams suit particulate duty; taped seams close the stitch-hole leak path chemical work demands — that distinction is exactly where the Tychem 4000 and 6000 earn their premium.
How much does the KleenGuard A20 cost?
From $141.70 on the linked Amazon listing; check the listing for the pack count at your size. Prices track the live listing.
Is the KleenGuard A20 waterproof?
No — it is a particulate fabric that sheds at most light mist; liquid work needs a laminate or coated suit.
Can I wear the KleenGuard A20 for asbestos or mold remediation?
For regulated abatement, crews spec a hood-and-boots Tyvek 400 TY122S so there is no gap at the footwear; this suit serves other duties better.
What color is the KleenGuard A20, and does color matter?
Blue Denim. Color is convention, not protection — white for particulate suits, yellow for chemical garments, blue for biological and site-visibility roles.
Can I wear the KleenGuard A20 over regular work clothes?
Yes — that is the intended use. Coveralls layer over clothing; size up so the seams are not loaded when you crouch.
What do I do with the KleenGuard A20 after use?
Doff at the boundary of the work area, folding the contaminated surface inward, and dispose per the standard that governs your hazard — regulated waste for asbestos, lead, or biological work; general industrial waste otherwise.

The Bottom Line
The KleenGuard A20 earns its slot in the lineup: breathable dry-particulate protection in a disposable garment at a defensible price. Pair it with the right respirator for drywall or silica dust — the suit stops the mess, not the inhalation hazard. Rated 4.1/5 on grade, configuration, and value for the intended hazard.
