La Sportiva Men's Aequilibrium Lite GTX Jacket
GORE-TEX implies Teflon-type coating, no public PFAS disclosure from La Sportiva
La Sportiva does not publicly disclose PFAS use or avoidance in this GTX jacket. GORE-TEX waterproofing typically contains Teflon-type coating-based Teflon-family coating, a PFAS class, though individual membrane composition is proprietary.

What La Sportiva Men's Aequilibrium Lite GTX is made of, ingredients and materials
The Aequilibrium Lite GTX uses a GORE-TEX laminate, which bonds a Teflon-family coating (Teflon-type coating-based) membrane to fabric layers for waterproofing and breathability. Teflon-type coating itself is stable during wear, but the manufacturing and fluorochemical processing introduce PFOA and other PFAS into the product during production. The jacket's outer shell is likely polyester or nylon with a water-repellent coating (water-repellent coating) finish, which historically used PFAS-based treatments; La Sportiva has not publicly disclosed whether they have switched to PFAS-free water-repellent coating alternatives.
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.
Antimony in polyester
The jacket's polyester outer shell may contain antimony oxide (catalyst used in polyester synthesis). Antimony leaching during wear is minimal in intact fabric, but degradation or damage could increase dermal contact over extended periods.
Microfiber shedding and textile degradation
Repeated washing and wear cause all synthetic jackets to shed microfibers; laminated products like GORE-TEX may degrade faster under UV and mechanical stress, increasing microfiber release into waterways and the environment over the product lifetime.
What’s reassuring
Formaldehyde / VOCs
No publicly reported formaldehyde concerns specific to La Sportiva jackets or GORE-TEX products; standard polyester and nylon fabrics may contain trace formaldehyde from manufacturing, but exposure during normal wear is negligible.

La Sportiva does not disclose dye sourcing or restricted azo-dye policies. No recalls or safety alerts related to azo dyes in this brand's apparel are on record.
Flame retardants
No evidence that La Sportiva adds flame-retardant chemicals to the Aequilibrium Lite GTX. GORE-TEX membranes do not inherently require flame retardants.

The brand's record and disclosure
La Sportiva, an Italian outdoor apparel company owned by Oberalp Group, has not issued public statements regarding PFAS phase-out, PFAS-free certifications, or chemical transparency for their jackets. The brand maintains no publicly available restricted substances list or third-party certifications (such as Bluesign, GOTS, or cradle-to-cradle) that would signal commitment to PFAS reduction. This silence on a known industry hazard contrasts with competitors like Patagonia and Arc'teryx, which have made formal commitments to PFAS elimination.
How it compares in its category
Most mid-to-premium hardshell jackets in the hiking/mountaineering category use either GORE-TEX (PFAS-containing) or competing membranes like eVent and Pertex Shield (also PFAS-based historically). Some brands now offer PFAS-free membranes (e.g., Patagonia's H2No, which uses polyurethane; Arc'teryx's Tizip), though at similar price points. The Aequilibrium Lite GTX sits in the typical mid-range for technical alpine gear and offers no differentiation regarding chemical safety.
If you buy it
Wash infrequently in cool water with minimal detergent to avoid accelerating any coating degradation; avoid high heat and tumble drying, which can stress the laminate and theoretically increase microfiber shedding. Do not use fabric softeners or waterproofing sprays, as these can interact with the GORE-TEX membrane. Replace the jacket if seams delaminate, the membrane develops pinholes, or the water-repellent coating visibly fails (water no longer beads). Proper care extends product life and limits the environmental release pathway for PFAS.
