Nomad · Water-Resistant Smart Rings & Bands
Nomad Sport Strap for Apple Watch 9/8/7/6/SE/5/4
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes elastomer strap, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

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.
Elastomer degradation and particle shedding
Over extended use or with UV exposure, elastomer can degrade and potentially shed microparticles. No recalls or complaints specific to this strap are on record, but degradation risk exists for any elastomer product over years of wear.
Mold or bacterial growth in strap crevices
Any porous or grooved elastomer band can trap moisture and harbor bacteria if not dried promptly after water exposure. This is not a material hazard but a hygiene risk common to all watch bands in humid or high-sweat conditions.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Allergen or irritant residuals from manufacturing
Elastomer formulations sometimes retain trace processing chemicals (e.g., vulcanization accelerators, slip agents). Nomad does not disclose residual testing; reactions are rare but possible in sensitized individuals.
Heavy metals
No recalls or regulatory findings have flagged heavy metals in Nomad Sport Strap colorants. Elastomer dyes and pigments are generally subject to EU and FDA limits, but Nomad does not publish material specifications.

Modern elastomers for wearables typically use non-formaldehyde cross-linking (e.g., sulfur vulcanization or peroxide cures). No evidence suggests this strap uses formaldehyde-releasing resins, which are more common in textiles.

What it's made of and why it matters
The Nomad Sport Strap is constructed from elastomer, a synthetic rubber compound designed for durability and flexibility in wearable applications. Elastomers do not inherently leach BPA, phthalates, or heavy metals when formulated to consumer product standards. The material's inert nature means it resists degradation from sweat, water, and normal body contact, which is why it is widely used in sports watch bands.
The brand's record and disclosure
Nomad has not published a formal PFAS statement or third-party material safety certification for this strap. The brand does not appear in major chemical safety controversies or product recalls related to elastomer bands. Nomad's product design emphasizes durability and material longevity, which indirectly reduces replacement frequency and lifecycle impact, though formal toxicology or restricted substance testing is not publicly documented.
How it compares in its category
Elastomer straps are associated with lower concern relative to some other Apple Watch band material choices. Unlike fabric bands (which can harbor bacteria or absorb cleaning chemicals), silicone or rubber alternatives (which may include residual monomers or slip agents), and metal/leather bands (which carry nickel or chromium contact risk), elastomer presents fewer known chemical exposure pathways. Most competitors in this segment operate under similar opacity regarding restricted substance testing.
If you buy it
Rinse the strap regularly with clean water and mild soap after sweat or salt exposure; elastomer does not require special conditioning. Avoid prolonged exposure to direct heat above 65 degrees Celsius or harsh solvents, which could degrade the material over time. Replace the strap if visible cracking, stickiness, or color bleeding appears. Store in a cool, dry place when not in use to extend lifespan.
