Finding a fully waterproof backpack that is completely free of PFCs/PFAS (perfluorocarbons) is entirely doable, as many outdoor gear brands have transitioned away from harmful forever chemicals in favor of polyurethane (PU) coatings, TPU laminates, and PFC-free DWR (Durable Water Repellent) treatments.[1]
Here are top options depending on how you plan to use your backpack:
-
Best For: Everyday carry (EDC), urban commuting, and tech protection.
-
Why it fits:
Black Ember builds high-precision, weather-proof urban packs using waterproof textiles and bonded-stitch construction. Their EmberTex line includes specific PFAS-free models designed to shed heavy rain safely without toxic chemicals. Check options on the Black Ember Store.
-
Best For: Paddling, watersports, and outdoor travel.
-
Why it fits: Constructed with 100% waterproof materials, welded seams, and a DrySeal roll-top closure. It is entirely PVC-free and relies on a polyurethane-coated polyester/nylon blend rather than fluorinated treatments to keep water out. View details on the Store.
