Women's Decathlon Ski Mid Length
Decathlon does not disclose water-repellent coating chemistry; assume fluorinated treatment risk.
Ski mid-length clothing typically uses polyester with applied water-repellent finish. Decathlon provides no public disclosure of water-repellent coating treatment chemistry or PFAS status. Uncertainty is high without lab testing.

What Women's Decathlon Ski Mid Length is made of, ingredients and materials
This is polyester yarn construction with an applied water-repellent (water-repellent coating) finish. Polyester itself is a synthetic polymer stable under normal wear and washing. The water-repellent coating is the material variable, Decathlon does not specify whether it uses fluorinated (PFAS-based) or fluorine-free chemistry. The finish degrades with washing and abrasion, which is why reapplication is common in outdoor apparel.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Formaldehyde / VOCs
Polyester textiles sometimes use formaldehyde-releasing resins in wrinkle resistance or finish bonding. Decathlon does not disclose this for this product. Exposure is primarily dermal and inhalation during wear; volatile release decreases with washing.
Source, ATSDR ↗Azo dyes and colorant toxins
Polyester is typically dyed with azo dyes, some of which can release carcinogenic amines under reductive conditions. No recall or test failure is on record for Decathlon ski wear, but raw material sourcing is not publicly disclosed.
water-repellent coating finish degradation and reapplication burden
Fluorinated water-repellent coating (if used) degrades with repeated washing. Without brand transparency, consumers cannot assess frequency of reapplication or confirm that replacement products are fluorine-free, extending potential exposure cycle.
Microplastic shedding from synthetic fibers
Polyester sheds microfibers during washing and wear, especially as the garment ages. This is not a direct consumer safety hazard but a persistence and environmental concern relevant to long-term use and disposal decisions.
What’s reassuring
Antimony in polyester catalyst residue
Polyester synthesis often uses antimony oxide as a catalyst; residual antimony may remain in the fiber. No specific findings of excess antimony in Decathlon polyester apparel are on record, and migration during normal wear is considered minimal.
The full breakdown
The brand's record and disclosure
Decathlon has not published a public commitment to PFAS-free water-repellent coating chemistry or detailed testing for this product line. The brand's general sustainability pages do not address per- and polyfluoroalkyl substance avoidance. No independent recalls or major safety findings specific to Decathlon ski wear are on record, but lack of transparency on water-repellent coating treatment chemistry is a significant gap in consumer information.
How it compares in its category
Most mid-market ski base layers and mid-weight jackets use polyester with water-repellent coating finishes; the category standard is polyester, not the finish itself. Premium brands (Arc'teryx, Patagonia) increasingly disclose fluorine-free water-repellent coating options; budget and mid-market brands, including Decathlon, often remain silent on chemistry. Untreated polyester alternatives exist but sacrifice water resistance.
If you buy it
Wash in cool water and air-dry to preserve the water-repellent coating as long as possible. Avoid fabric softeners and high heat, which accelerate finish breakdown. Expect to reapply commercial water-repellent coating treatment after 5-10 washes depending on use intensity. If the finish fails (water no longer beads), replacement or re-treatment is your choice point, not an immediate safety trigger; the polyester substrate itself remains functional.
