O'Neill Epic Back Zip Full Wetsuit
High PFAS risk from waterproof treatment; no brand transparency available.
O'Neill wetsuits use neoprene with water-resistant coatings on the outer fabric to boost durability. The brand stays silent on PFAS use, so legacy water-repellent coating formulas may contain long-chain PFOA or similar compounds common in wetsuits.

What O'Neill Epic Back Zip Full Wetsuit is made of, ingredients and materials
This wetsuit uses neoprene as the core insulating material, a synthetic rubber that is chemically stable and does not leach significantly during normal water exposure. The exterior is nylon fabric treated with water-repellent coating (water-repellent coating) coating, which is where PFAS chemicals are most likely present to achieve water-shedding performance. Neoprene itself is not known to degrade into hazardous monomers or leach metals; the risk profile is dominated by the surface treatment, not the bulk material.
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 surface coating degradation and leaching
Nylon-based water-repellent coating treatments on wetsuits typically contain PFAS or PFAS alternatives; flexing and abrasion during wear degrades the coating, potentially increasing leachate into skin and water. No brand testing data is publicly available to quantify risk magnitude.
Neoprene off-gassing and volatile organic compounds
Neoprene is often manufactured using chlorine-based or isocyanate chemistry; some off-gassing of volatile compounds can occur when new, though it is not classified as a major hazard class. Airing the wetsuit indoors before first use may reduce initial exposure.
Nylon microfiber shedding during wear and washing
The nylon exterior sheds microfibers into water during use and washing, particularly as the coating degrades. This contributes to microplastic pollution but is not a direct health hazard specific to this product's composition.
What’s reassuring
Skin irritation from dyes or finish residues
No reported cases of acute dermatitis from O'Neill wetsuits are documented. Neoprene and nylon are generally well-tolerated; however, individuals with sensitive skin may react to residual dyes or sizing agents before first wash.
Chlorine byproduct absorption during chlorinated pool use
If used in chlorinated pools, neoprene can absorb chlorine; however, this is an exposure route rather than a product hazard, and is not specific to O'Neill branding or neoprene chemistry.
How is this PFAS grade calculated?
The brand's record and disclosure
O'Neill, one of the largest wetsuit manufacturers globally, does not publicly disclose details about PFAS use, alternatives tested, or reduction timelines on wetsuits. The brand has not voluntarily committed to PFAS phase-out in marketing or sustainability statements reviewed in public sources. This silence is typical across the industry, but it represents a lack of transparency that makes independent assessment difficult. No major recalls or safety violations specific to O'Neill wetsuits are established in public records.
How it compares in its category
Most commercial wetsuits, including competitors like Rip Curl and Xcel, rely on similar neoprene cores with water-repellent coating nylon exteriors, so PFAS exposure is a category-wide issue rather than O'Neill-specific. Some smaller brands and premium manufacturers now offer PFAS-free water-repellent coating alternatives (e.g., wax-based or fluorocarbon-free) but they remain niche and cost more. O'Neill's Epic line is mid-to-premium market positioning; it is neither the most transparent nor the most opaque in its price tier. This product sits in the mainstream of the category for both performance and chemical trade-offs.
If you buy it
Rinse the wetsuit thoroughly in fresh water after each saltwater session to minimize skin contact with surface treatments and salt accumulation. Avoid machine washing in hot water, which can accelerate nylon degradation and may increase leaching; hand rinse instead. Store in a cool, dry place away from direct sunlight to slow UV breakdown of the nylon exterior. Replace when the exterior nylon shows visible cracks, flaking, or discoloration, as this signals loss of the water-repellent coating and potential increased leaching during use.
