Skip until Deuter discloses water-repellent coating treatment composition.

Verdict · SkipTrekking pack with undisclosed water-repellent coating and poor PFAS grade; buy only if you accept unknown water-repellent coating chemistry and commit to extended use to justify environmental cost.

Deuter's trekking pack uses nylon with an unspecified waterproof finish. No public disclosure of PFAS-free status or water-repellent coating chemistry raises concern for conventional fluorinated treatments.

What Aircontact Lite 45+10 SL Trekking Pack is made of, ingredients and materials

The Aircontact Lite 45+10 SL uses nylon fabric with an unspecified water-repellent (water-repellent coating) coating. Nylon itself is stable and non-leaching under normal use, but the water-repellent coating treatment applied to the surface is the critical unknown. Deuter does not publicly disclose whether this coating uses PFAS-based chemistry (common in outdoor gear) or PFAS-free alternatives. Without that information, the environmental and potential dermal exposure profile cannot be assessed.

What’s concerning

♾️

Waterproof / stain-resistant treatment

Water-repellent coating treatments have historically used PFAS.

85/ 100
🍳

Water-repellent (water-repellent coating) coating composition unknown

The coating is present but Deuter does not disclose whether it contains PFAS or PFAS alternatives. Nylon fabric itself does not leach; any concern attaches to the surface treatment, which may degrade or migrate with washing or abrasion over years of use.

70/ 100
🫧

Microfiber shedding during wear and washing

All synthetic textiles shed microfibers, but nylon used in trekking packs is relatively durable and shedding is generally lower than in lighter knits. Washing is a known shedding trigger; infrequent cold washing reduces this.

70/ 100

What’s reassuring

✅

Dye or coating off-gassing (volatile organic compounds)

No off-gassing incidents or complaints are on record for Deuter packs. Nylon is not known to release formaldehyde or other volatile compounds at room temperature when stored dry. The water-repellent coating does not typically off-gas under normal storage or use conditions.

95/ 100
✅

Metal hardware degradation (buckles, zippers, attachment points)

Deuter uses aluminum and stainless-steel hardware on this model; neither is known to leach under normal outdoor exposure. No corrosion or metal contamination incidents are documented. Risk increases only if hardware is damaged or if the pack is stored in highly corrosive (salt-spray) environments for months.

95/ 100
🔥

Flame retardants

No flame-retardant additives are known to be used in nylon trekking packs. This is a footwear and furniture hazard, not typical for outdoor bags, and no disclosures or incidents link this product to brominated or phosphorus-based flame retardants.

How is this PFAS grade calculated?

The brand's record and disclosure

Deuter has not made public commitments to PFAS phase-out or disclosed water-repellent coating chemistry for their trekking packs. The brand's silence on this standard industry disclosure is notable, as major outdoor manufacturers increasingly specify fluorocarbon-free or PFAS-free treatments. No safety recalls or contamination incidents are on record for this specific model. The lack of transparency on a hazard class known to persist in outdoor textiles represents a disclosure gap rather than a confirmed problem.

How it compares in its category

Mid-range trekking packs in this size and price tier often use nylon with water-repellent coating treatment; Deuter's omission of composition details is common but increasingly lagging. Premium outdoor brands (Patagonia, Arc'teryx, some models from The North Face) now label PFAS-free water-repellent coating or disclose fluorocarbon chemistry. Budget alternatives may use less durable coatings that wear off faster, reducing overall environmental persistence. This pack's durability is its advantage, but that longevity is only justified if you use it heavily and repeatedly.

If you buy it

Wash infrequently (2-3 times per year at most) with cool water and mild detergent to preserve the water-repellent coating and minimize any potential leaching. Avoid machine drying or heat treatments. Store in a dry place to prevent mold and reduce need for retreatment. If the water-repellent coating visibly fails (water beads less, fabric darkens when wet), you can repreat it with a PFAS-free aerosol or liquid water-repellent coating product from outdoor retailers; this extends the pack's life and lets you control the chemistry.
