Skip until coating disclosed by brand.
Cascade Mountain Tech won't reveal what waterproof coating treats this rescue bag or mention PFAS. Rescue bags normally use water-repellent coating treatments, but you need documentation before buying.

What Cascade Rescue Waterproof Rescue/Evac bag is made of, ingredients and materials
This bag is constructed from polyester fabric with an applied waterproof coating of unspecified chemistry. Polyester itself is a stable plastic polymer with low toxicity during normal use, but the waterproof finish is the critical unknown. Most waterproof coatings on outdoor textiles historically use either Teflon-type coating (Teflon), polyurethane, or silicone formulations; some legacy products used PFAS-heavy compounds. Without the brand disclosing coating type and chemistry, you cannot rule out problematic additives. The bag will shed microfibers over time, particularly if abraded or washed aggressively.
What’s concerning
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Undisclosed waterproof coating composition
The brand has not publicly specified whether the coating uses PFAS, fluorocarbon, polyurethane, or silicone chemistry. This opacity prevents assessment of whether the bag carries legacy PFAS or newer alternatives. Contact the manufacturer directly if chemical composition is a dealbreaker.
Microfiber shedding from polyester
Polyester textiles shed microplastics during wear, washing, and abrasion. A rescue bag stored in contact with skin or packed with food items in an emergency could transfer fibers. Effect on human health from ingestion remains under study, but shedding is a known feature of polyester products.
Coating degradation over time and with use
Budget waterproof coatings often degrade faster than premium formulations, especially with UV exposure, heat, or chemical contact. As the coating fails, the bag may shed polymer particles and lose water resistance. No durability data from Cascade Mountain Tech is publicly available.
What’s reassuring
Formaldehyde / VOCs
Polyester fabric can be treated with formaldehyde-based resins for wrinkle resistance or stiffness. No specific formaldehyde reports exist for this Cascade model, but the brand does not advertise formaldehyde-free finishing. Risk is low for outdoor gear versus clothing, since the bag is not worn against skin.
Source, ATSDR ↗Azo dyes in colored polyester
Bright colors in polyester are sometimes produced using azo dyes, some of which can break down into aromatic amines under heat or moisture. This bag is typically available in neutral colors (black, tan, olive), which are lower-risk for azo dyes, but composition is unconfirmed.
How is this PFAS grade calculated?
The brand's record and disclosure
Cascade Mountain Tech is a budget-tier outdoor brand with minimal public transparency on material sourcing or chemical safety. No certifications (such as OEKO-TEX, Bluesign, or GOTS) are evident in standard product information. The brand has not publicly committed to PFAS phase-out or provided technical data sheets for their waterproof coatings. This silence on coating composition is the main red flag and prevents independent verification of safety.
How it compares in its category
Budget rescue and evac bags typically use the same polyester-plus-coating approach as this product. Mid-range outdoor brands (Arc'teryx, Black Diamond) often disclose PFOA/PFOS testing results and use newer, lower-PFAS fluorocarbon or non-fluorine water repellents. Premium rescue gear increasingly uses PFC-free silicone or wax-based coatings. Cascade sits at the low-transparency end of the market, offering function at the cost of certainty about what chemicals you're carrying.
If you buy it
Store the bag in a well-ventilated space for the first 48 hours to allow any volatile off-gassing from the coating to disperse. Avoid hand-washing or machine-washing if possible; spot-clean with mild soap and air-dry to minimize microfiber shedding and coating degradation. Do not dry-clean or expose to high heat, which may damage the waterproof layer and potentially release coating particles. Replace the bag if the coating begins to flake, peel, or visibly degrade, as a failed waterproof layer loses its function and may shed accelerated microfiber.
