Reviewed by Steven Eaton, WC Safety Editorial

The DuPont Tyvek 400 TY122S coverall is a white disposable protective suit built on Tyvek 400 flash-spunbond HDPE. The TY122S exists for one reason: regulated abatement work where the suit must meet the boot. The attached skid-resistant boots close the ankle gap that a standard suit plus shoe covers leaves, which is why it is the default spec for asbestos and heavy mold jobs. Our listing starts at the listed price, with the size run on the linked Amazon page.

Why the DuPont Tyvek 400 TY122S Stands Out

Published July 1, 2026 · Last updated July 27, 2026

The TY122S exists for one reason: regulated abatement work where the suit must meet the boot. The attached skid-resistant boots close the ankle gap that a standard suit plus shoe covers leaves, which is why it is the default spec for asbestos and heavy mold jobs.

Fabric, Configuration and Protection

Type 5/6 — head-to-ankle particulate coverage with no gap at the footwear. Configuration: attached hood plus attached skid-resistant boots, elastic wrists, serged seams. Tape the wrist interfaces for containment work; the boots handle the other end. 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: General dusty work where boots are overkill — the hooded TY127S costs less and dons faster. 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

Who Should Buy It

Consider the DuPont Tyvek 400 TY122S if you are asbestos abatement and mold remediation crews who need attached boots and single-use disposal.

Who Should Skip It

Skip it for general dusty work where boots are overkill — the hooded TY127S costs less and dons faster.

How It Compares

Same fabric as the TY127S — the choice is purely configuration: attached boots for abatement, plain ankles for everything else. 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

The Bottom Line

The DuPont Tyvek 400 TY122S earns its slot in the lineup: type 5/6 in a disposable garment at a defensible price. Tape the wrist interfaces for containment work; the boots handle the other end. Rated 4.4/5 on grade, configuration, and value for the intended hazard.

Common questions

What fabric is the DuPont Tyvek 400 TY122S made of?

Tyvek 400 flash-spunbond HDPE. That fabric choice is the core of what it protects against and how it wears.

What sizes does the DuPont Tyvek 400 TY122S 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 DuPont Tyvek 400 TY122S 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.

DuPont Tyvek 400 TY122S vs Tyvek 400 TY127S — which should I buy?

Same fabric as the TY127S — the choice is purely configuration: attached boots for abatement, plain ankles for everything else.

Does the DuPont Tyvek 400 TY122S have a hood?

Yes — attached hood plus attached skid-resistant boots, elastic wrists, serged seams

What respirator should I pair with the DuPont Tyvek 400 TY122S?

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 DuPont Tyvek 400 TY122S sealed?

Attached hood plus attached skid-resistant boots, elastic wrists, serged seams. 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 DuPont Tyvek 400 TY122S cost?

From the listed price on the linked Amazon listing; check the listing for the pack count at your size. Prices track the live listing.

Is the DuPont Tyvek 400 TY122S 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 DuPont Tyvek 400 TY122S for asbestos or mold remediation?

Yes — attached hood and boots make it the abatement standard; tape the wrists and dispose of it as regulated waste.

What color is the DuPont Tyvek 400 TY122S, and does color matter?

White. Color is convention, not protection — white for particulate suits, yellow for chemical garments, blue for biological and site-visibility roles.

Can I wear the DuPont Tyvek 400 TY122S 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 DuPont Tyvek 400 TY122S 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.

Where does the DuPont Tyvek 400 TY122S fit in the WC Safety coverall lineup?

See how it ranks against all ten picks in the best disposable coveralls guide, or browse the disposable coveralls collection for the full fabric ladder.

Does the rating on the box equal the protection I get?

No. Published ratings come from laboratory conditions. Regulators apply derating precisely because real fit is worse, and the derated figure is the one to plan from.

Sources. Requirements referenced here come from OSHA 29 CFR 1910 and the NIOSH recommendations. Where a consensus standard governs, the ANSI document is named in the text.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.

Our methodology

Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
