Tecnica Men's Plasma Mid GTX
Gore-Tex likely contains PFAS; no brand disclosure on treatments.
This hiking boot uses Gore-Tex, a Teflon-type coating membrane traditionally made with PFAS, for waterproofing. Tecnica provides no PFAS disclosure or certification for treatments.

What Tecnica Men's Plasma Mid GTX is made of, ingredients and materials
These boots use nylon fabric with a Gore-Tex waterproof breathable membrane laminated to the inside, plus a water-repellent coating (water-repellent coating) finish on the outer surface. Gore-Tex membranes historically rely on PFAS chemistry for their water-shedding properties, though the company has not publicly disclosed treatment specifics for this model. Nylon itself is a stable synthetic polymer with low leaching risk during normal wear; the water-repellent coating finish is where chemical durability concerns center, as it degrades with washing and reapplication cycles.
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.
water-repellent coating finish degradation and reapplication
Water-repellent coating coatings on nylon degrade after 50-100 wash cycles. Consumer reapplication products typically contain fluorinated or silicone-based chemicals; repeated treatment escalates exposure and environmental release.
Gore-Tex membrane delamination
Over time and with thermal stress, the laminated membrane can separate from the nylon backing, releasing small particulates. No field data on microplastic or adhesive leachate quantity from this product specifically, but delamination is a known failure mode in Gore-Tex footwear.
Antimony in polyester components
If inner linings or thread contain polyester, antimony (a catalyst used in polyester synthesis) may be present at trace levels. No specific testing of this model on record; exposure during wear is minimal, but manufacturing and disposal pathways carry environmental concern.
What’s reassuring
Formaldehyde / VOCs
No recalls or published testing for formaldehyde or formaldehyde-releasing agents in Tecnica nylon boots. Nylon fabric is typically lower-risk for formaldehyde than cotton or cellulose blends, and no evidence of this model using cross-linking resins.

Tecnica does not disclose dye chemistry or pigment sourcing. No recalls or test reports of excessive heavy metals or banned azo dyes in this brand. Risk is not elevated compared to standard outdoor footwear, but opacity remains.

The brand's record and disclosure
Tecnica has not issued public statements on PFAS use, treatment chemicals, or commitments to phase-out fluorinated compounds in footwear. The company does not list third-party certifications (e.g., OEKO-TEX, Cradle to Cradle) for this model on available product pages. Without transparency on water-repellent coating chemistry or sourcing, consumers cannot verify whether non-fluorinated alternatives were considered.
How it compares in its category
Mid-weight hiking boots in this price range typically use either Gore-Tex or similar PFAS-containing membranes (Pertex, eVent, etc.) or non-membrane synthetic linings. Competing brands like Scarpa and Salomon offer similar constructions with identical PFAS exposure; few mainstream mountaineering boots avoid fluorinated water treatments entirely. The Plasma Mid GTX sits in the conventional market segment where PFAS in membrane and water-repellent coating finish is standard practice, not exceptional.
If you buy it
Wash gently by hand in cool water; machine washing accelerates water-repellent coating degradation and may necessitate reapplication with products that often contain PFAS or other fluorinated chemicals. Air-dry only; heat (radiators, dryers) can damage the Gore-Tex bond and nylon fibers. Replace or resole when structural integrity declines rather than attempting chemical renewal, which adds cumulative exposure. Store dry in a cool place to slow membrane and adhesive aging.
