Columbia Men's Coreshot Shell Jacket
water-repellent coating treatment unknown; Columbia silent on PFAS disclosure.
Columbia does not publicly disclose PFAS use or avoidance in this jacket. water-repellent coating-treated outerwear often uses PFAS, but specific treatment chemistry is undisclosed. Request brand clarification before purchase.

Material
Nylon shell with water-repellent coating water-repellent finish
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Microplastics
Nylon water-repellent coating finishes degrade with washing and wear, potentially shedding polymer particles and finish residue. If the water-repellent coating is PFAS-based (unknown for this product), degradation products may enter wastewater. Extent of harm depends on unknown finish chemistry.
Source: EPA ↗VOC off-gassing from synthetic finishes
New nylon jackets with water-repellent coating and any applied adhesives or linings may off-gas volatile compounds during the first few wears or when heated. Airing out the jacket outdoors before first wear can reduce exposure. This is typical for outdoor gear but intensity is unknown without finish disclosure.
What’s reassuring
Formaldehyde / VOCs
No public reports or recalls of formaldehyde contamination in Columbia nylon shells. The black or standard colorways typical of this jacket are lower-risk for azo dye issues compared to deep or reactive dyes, but Columbia does not disclose dye standards.
Source: ATSDR ↗Azo dyes / non-compliant colorants
Columbia complies with REACH and CPSIA basic dye restrictions, but does not publish detailed colorant audits. Risk is low for standard colors but unverified for specialty finishes or recent production batches.
Antimony in polyester blends
This jacket is listed as nylon shell with no reported polyester content, so antimony catalyst contamination is not relevant.
The full breakdown
What it's made of and why it matters
This jacket uses nylon as the outer shell, a synthetic polymer valued for durability and water resistance. The water-repellent coating (water-repellent coating) finish applied to the nylon surface is the key unknown: Columbia does not publicly disclose whether this treatment contains PFAS-based chemistries (like C8 fluorocarbons) or newer alternatives. Nylon itself is stable under normal wear and does not leach hazardous chemicals, but the finish chemistry is opaque.
The brand's record and disclosure
Columbia Sportswear has not published a clear PFAS elimination timeline or water-repellent coating material disclosure comparable to brands like Patagonia or Arc'teryx. The company has faced no major recalls or documented safety crises with this product line, but the lack of transparency on water-repellent chemistry is a red flag in an industry where PFAS-free alternatives are increasingly available. Columbia's silence suggests either legacy PFAS use or indifference to consumer disclosure demands.
How it compares in its category
Most mid-market outdoor shell jackets still use fluorocarbon-based water-repellent coating finishes, making Columbia typical rather than ahead of the curve. Premium brands (Patagonia, Rab, some Arc'teryx lines) now offer PFAS-free water-repellent coating or wax-based water resistance, while budget options often use untested finishes. This jacket sits in the murky middle: competent performance, conventional (likely problematic) chemistry, no commitment to safer alternatives.
If you buy it
Wash the jacket separately in cold water with minimal agitation to reduce fiber shedding and preserve the water-repellent coating as long as possible. Avoid dry cleaning, which can degrade the finish and concentrate any water-repellent coating residue. Do not expose to prolonged heat (dryer on high, ironing, or direct sunlight for weeks) as this may compromise the nylon and accelerate coating breakdown. Re-water-repellent coating treatment at end-of-life should use a PFAS-free product if available (brands like Nikwax offer alternatives).
