Thule Chasm Carry-On Wheeled Duffel Bag
water-repellent coating-coated nylon duffel, likely PFAS-treated. Details unclear.
Thule Chasm uses ballistic nylon with water-repellent treatment typical of wheeled luggage. Brand does not disclose PFAS content or alternatives; water-repellent coating coatings often contain PFAS.

The full breakdown
What it's made of and why it matters
The Chasm Carry-On uses ballistic nylon, a tightly woven polyamide fabric prized for tear and abrasion resistance, paired with a durable water-repellant (water-repellent coating) finish. water-repellent coating coatings on luggage are typically fluorochemical-based (PFAS compounds like Teflon-type coating or C6/C8 Teflon-family coating) to shed water without waterproofing completely, which maintains breathability and luggage weight. The nylon itself is chemically stable during normal use; concern centers on the treatment layer and any potential leaching during moisture exposure or mechanical wear.
The brand's record and disclosure
Thule has not publicly disclosed the specific water-repellent coating chemistry used on the Chasm line or committed to PFAS-free alternatives, despite increasing market transparency on this issue from competitors. The brand maintains strong reputation for durability and design but has been silent on chemical safety disclosures and third-party testing certifications for luggage materials. No major recalls or safety incidents specific to this product line are on record.
How it compares in its category
Most mid-range wheeled duffels (Samsonite, Away, Peak Design) also use water-repellent coating-treated nylon without detailed chemical transparency. Some premium brands (e.g., Patagonia) now disclose fluorochemical-free or C6-only treatments; budget alternatives often skip water-repellent coating entirely or use less durable coatings. The Chasm sits mid-market: likely PFAS-treated but with excellent fabric durability, meaning longer product life offsets some chemical concern.
If you buy it
Store in a cool, dry place away from heat sources and direct sunlight to minimize any leaching from the water-repellent coating. Avoid prolonged skin contact with the interior (use linings or packing cubes if sensitive) and do not machine wash, as agitation and moisture may accelerate coating degradation. Inspect seams and surface annually for pilling or tears; replace the bag if the nylon becomes heavily abraded and exposed fibers show. For food storage or direct contact with sensitive items, line the interior with a breathable fabric barrier.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
PFAS in water-repellent coating (reported but unconfirmed for this specific product)
Ballistic nylon luggage typically uses fluorochemical water-repellent coating treatments; Thule has not disclosed whether theirs is PFAS-based. Leaching risk is low during normal dry storage but increases with moisture, heat, or mechanical wear.
Microplastic shedding from nylon fabric wear
Ballistic nylon sheds microfibers when abraded, especially at stress points (edges, seams, wheels). Risk is minimal for luggage itself but relevant if fabric debris contacts food or is inhaled during unpacking in enclosed spaces.
Lead or cadmium in dyes or hardware
No reports or recalls of heavy metal contamination in Thule luggage. Ballistic nylon and metal wheels/zippers are typically dyed and plated using regulated industrial processes, though Thule does not publish third-party test results.
VOC or formaldehyde off-gassing from synthetic materials
Ballistic polyamide and standard water-repellent coating treatments do not typically release formaldehyde or significant VOCs under normal storage. Brief off-odor when new is normal and dissipates within days of airing out.
Coating degradation and loss of water resistance over time
water-repellent coating finishes on all luggage naturally degrade with use, washing, and UV exposure. Thule's is durable but not permanent; water-beading properties typically decline noticeably after 2-5 years of frequent use.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 40% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
