MSR DromLite Bag
Skip pending PFAS clarity; outdoor gear often uses PFAS water-repellent coating.
MSR DromLite Bag uses nylon ripstop with water-repellent coating (water-repellent coating) coating, a common PFAS delivery method in outdoor products. No PFAS transparency from brand; contact MSR directly for coating specifics.

The full breakdown
What it's made of and why it matters
The DromLite Bag uses nylon ripstop fabric, a densely woven polyamide that resists tearing and abrasion. A water-repellent coating (water-repellent coating) coating is applied to the outer surface to shed moisture. Nylon itself is chemically stable and does not leach into food or skin during normal use. The critical unknown is the water-repellent coating chemistry: modern water-repellent coating can be PFAS-based (fluorinated) or PFAS-free, and MSR has not publicly disclosed which formulation is used on this product.
The brand's record and disclosure
MSR (Mountain Safety Research, owned by Cascade Designs) has not published detailed PFAS sourcing statements or third-party testing results for their gear as of available public records. The brand does not maintain a published restricted substances list or chemical transparency report comparable to outdoor peers like Patagonia or The North Face. This silence on water-repellent coating chemistry is typical of many outdoor equipment makers but represents a gap in consumer assurance.
How it compares in its category
Nylon ripstop bags are industry standard for outdoor storage and carry systems. Most competing products use identical or very similar nylon with water-repellent coating coatings of undisclosed chemistry. Few mainstream outdoor brands offer PFAS-free water-repellent coating on all products, though some (e.g., Paragon, certain REI Co-op lines) have begun transitioning. The DromLite Bag is not an outlier in chemical transparency, it reflects the broader outdoor industry norm of limited disclosure.
If you buy it
Use the bag for dry goods storage, outdoor transport, and camping use as intended; nylon is not a food-contact material and poses no chemical risk in these applications. Avoid prolonged contact with skin for people with sensitive skin, as the coating texture may cause minor irritation in rare cases. water-repellent coating coatings degrade over 2-5 years with washing and UV exposure; expect to replace the bag or accept reduced water resistance. Hand wash gently with mild soap if needed; machine washing accelerates coating breakdown.
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.”
Azo dyes in nylon fabric
Nylon ripstop is typically dyed with acid or disperse dyes; carcinogenic azo dyes are rare in outdoor gear nylon but not explicitly excluded in public MSR specifications. No recalls or reports of azo dye contamination in MSR bags are on record.
water-repellent coating durability and reapplication toxicity
The water-repellent coating will degrade and may eventually require reapplication or replacement. Consumer water-repellent coating spray reapplication products often contain PFAS or solvents; MSR does not specify approved recoating methods, leaving users to choose potentially hazardous aftermarket products.
Formaldehyde resins in fabric finishing
Nylon ripstop may be finished with formaldehyde-based resins for wrinkle resistance or sizing. No formaldehyde reports or recalls exist for MSR outdoor bags. Off-gassing risk is minimal for non-apparel storage items.
Microplastic shedding from synthetic fabric
Nylon ripstop sheds microfibers when abraded, washed, or worn. This is not a health hazard during normal use but a cumulative environmental concern. MSR does not disclose fiber shedding rates or recommend washing practices to minimize microplastic release.
Flame retardants in coating or backing
Outdoor ripstop bags are not typically treated with flame retardants unless marketed as fire-resistant. No public information indicates MSR applies flame retardants to the DromLite Bag.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
