Outdoor Products All Purpose Dry Sacks
Ask brand about waterproof coating chemistry before buying these sacks.
These dry sacks use waterproof water-repellent coating for water protection, but the brand does not reveal what chemicals create the waterproof effect. You cannot verify PFAS content without brand transparency.

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.
water-repellent coating volatilization (thermal)
If the coating contains legacy PFAS or other volatile additives, exposure risk is low under normal storage and use but could increase with heat, direct sunlight, or mechanical stress. No specific thermal data for this product model is available.
Coating adhesion and microparticle shedding over time
As water-repellent coating coatings degrade with age and washing, microscopic particles may shed into water or soil during outdoor use. Long-term environmental impact is poorly characterized, and this product carries no durability or shedding warranty in public materials.
What’s reassuring
Azo dyes in fabric base
No documented azo dye concerns or safety violations reported for Outdoor Products dry sacks. Nylon and polyester bases are typically low-risk for azo dye contamination, though certification data would confirm this.
Antimony in polyester (if used)
If the fabric base is 100% polyester, antimony catalysts may be present at trace levels, but external-use dry sacks present negligible skin or ingestion risk. No recalls or testing data specific to this product indicate elevated antimony.
Formaldehyde / VOCs
Waterproof coatings and fabric finishes may contain formaldehyde releasers, but no public safety alerts or testing results for Outdoor Products dry sacks document this hazard. Off-gassing from external gear is minimal given low surface contact.

What it's made of and why it matters
Outdoor Products All Purpose Dry Sacks are constructed from a fabric base (likely nylon or polyester) treated with a waterproof water-repellent coating (water-repellent coating) coating of unspecified chemistry. water-repellent coating coatings historically relied on PFAS compounds to achieve water resistance, though some manufacturers have shifted to alternatives not linked to PFAS in recent years. The brand has not publicly disclosed which chemistry it uses, making the actual hazard profile of the coating unknown without direct testing or brand statement.
The brand's record and disclosure
Outdoor Products maintains a minimal public stance on chemical composition and safety certifications. No major recalls or safety controversies specific to this dry sack line are documented in public records. The brand has not released statements about PFAS-free coatings, fluorine-free waterproofing, or third-party certifications (such as STANDARD 100 or Bluesign approval), which are increasingly expected for apparel and gear in this category.
How it compares in its category
Dry sacks occupy a niche in outdoor gear where waterproofing is essential but exposure is typically external and short-term. Competitors like Sea to Summit and Patagonia have begun disclosing water-repellent coating chemistry or committing to PFAS reduction, while other budget brands remain silent. Outdoor Products' lack of transparency places it in the middle-to-lower disclosure tier; many outdoor retailers now flag non-compliant gear and some brands have already eliminated older PFAS-based water-repellent coating formulations.
If you buy it
Dry sacks are low-contact external gear with minimal ingestion or inhalation risk. Store in a cool, dry location away from direct heat (do not dry-clean or tumble-dry at high temperature, which can degrade coatings and release volatiles). Avoid prolonged skin contact with wet coating if you have sensitive skin, and rinse hands after extended handling. Inspect seams and coating for wear annually; replace if waterproofing visibly degrades or flakes, as this signals breakdown of the water-repellent coating layer.
