Nftigb Nylon Watch Band for Coros Nomad Smartwatch Suunto 7/9 24mm Adjustable Woven Strap for Outdoor Climbing Sports
Lower concern. Woven nylon with no stated coating or water-resistant finish.
This watch band is woven nylon fabric with no water-repellent finish on record and no coating chemistry stated. The brand has no PFAS statement on record. Untreated nylon is not a material linked to PFAS.

Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Formaldehyde / VOCs
Woven nylon requires dyeing to achieve color. No dye chemistry or testing disclosed by Nftigb. Budget manufacturers may use cheaper azo dyes (some of which can release carcinogenic amines) or formaldehyde-based resin finishes without disclosure. Risk is low due to brief skin contact and outdoor use context, but unknown.
Source, ATSDR ↗Heavy metals
Some synthetic dyes contain trace cadmium, lead, or nickel. No independent testing published for this product. Nylon's non-porous weave limits dermal absorption, and sweat contact is intermittent, but sensitivities or nickel allergy could pose localized irritation risk if present.
Source, FDA ↗Formaldehyde / VOCs
Nylon may receive formaldehyde-based resin treatments to improve dimensional stability or wrinkle resistance. No brand disclosure of finishing chemicals provided. Off-gassing would be minimal given the small surface area and outdoor use, but chemical composition remains unverified.
Source, ATSDR ↗Microplastics
Woven nylon fibers can shed microplastics through abrasion, friction, or washing. The quantity and environmental impact from a single watch band is negligible, but care instructions (hand-washing, avoiding harsh friction) can minimize fiber loss.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Antimony in synthetic fibers
Antimony is used as a catalyst in polyester and PET production, not nylon. Nylon watch bands do not require this additive, so antimony contamination is not a concern for this material type.
The full breakdown
What it's made of and why it matters
This product is woven nylon fabric, a synthetic polymer made from polyamide chains. Nylon itself is chemically inert when untreated and does not inherently contain PFAS, heavy metals, or known endocrine disruptors in its base form. The weave construction creates durability for sports use without requiring chemical coatings that would introduce hazards like flame retardants or durable water repellents (which often contain PFAS). The watch band format means minimal skin contact duration and no food contact, reducing exposure risk from any trace residues.
The brand's record and disclosure
Nftigb/Nomad does not publicly disclose materials sourcing, dyeing practices, or chemical safety testing for this band. No independent certifications (Oeko-Tex, GOTS, or similar) are advertised. The brand maintains silence on PFAS and other chemical treatments, which is typical for budget sportswear accessory makers but prevents verification that azo dyes, formaldehyde resins, or antimony (common in polyester but not nylon) were avoided. No recalls or safety incidents for this specific product are on record.
How it compares in its category
Woven nylon bands are a standard, low-hazard choice for smartwatch straps compared to silicone (which can leach plasticizers) or leather (which may contain heavy metals in tanning). Nylon avoids the flame retardant treatments sometimes applied to athletic textiles, since watch bands do not require flammability compliance. The budget positioning means chemical testing is unlikely, but the material itself represents a lower concern synthetic option in sportswear.
If you buy it
Wash the band separately in cool water before first wear to remove any loose dyes or dust from manufacturing. Avoid prolonged heat exposure or direct sunlight when not in use, as nylon can degrade or discolor. Replace the band if weaving becomes frayed or if any odor develops, which may signal mold growth in the fabric fibers. Hand-wash occasionally with mild soap; machine washing is not recommended as it accelerates wear.
