Lower concern, but Spigen shares no PFAS information on band materials.
This sport band likely uses fluoroelastomer rubber but Spigen publishes no PFAS disclosures or certifications. Material choice points to lower risk, though transparency is absent.

No PFAS disclosure

Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Formaldehyde / VOCs
Fluoroelastomer bands may contain formaldehyde-releasing cross-linkers or curing agents. Spigen does not disclose the curing chemistry; skin contact exposure is expected to be minimal if present, as the material is fully cured before sale.
Source, ATSDR ↗Azo dyes and synthetic colorant toxicity
The khaki color is achieved with synthetic dyes or pigments; Spigen does not specify whether restricted azo dyes (arylamines) or heavy-metal-based pigments are used. Migration into sweat is considered low risk for elastomers, but no third-party testing is available for this specific product.
PFAS
Fluoroelastomer itself may contain fluorinated oligomers, and water-repellent surface treatments on sport bands sometimes include PFOA or PFOS precursors. Spigen's silence on PFAS use means this cannot be ruled out, though typical sport band formulations use lower-risk PFAS alternatives.
Source, ATSDR ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Flame retardants
No flame retardants are typically required for elastomer watch bands, and none have been reported in fluoroelastomer sport bands from mainstream manufacturers. Spigen has not disclosed additives, so residual levels cannot be ruled out but are not established in this product class.
Source, EPA ↗Nickel or metal alloy leaching from watch case contact
This hazard applies to the watch case attachment points, not the band material itself. If the band connector is not metal or is nickel-plated stainless steel, skin sensitization risk is low. No Spigen-specific issues are on record.
The full breakdown
What it's made of and why it matters
This Spigen band is fluoroelastomer (synthetic rubber), a non-porous elastomer commonly used in sports watch straps because it resists sweat, UV damage, and temperature swings better than silicone. Fluoroelastomer is chemically stable and does not typically leach additives into skin under normal wear. The material is inert enough that medical and industrial applications rely on it, though the specific formulation and any flame retardants or colorants added by Spigen are not publicly disclosed.
The brand's record and disclosure
Spigen is a South Korean accessories manufacturer with no known safety recalls or regulatory violations on record for watch bands. The company does not publish a PFAS statement or material safety data sheet for this product, which creates a disclosure gap. Spigen does not claim third-party certifications (e.g., OEKO-TEX, Bluesign) for textile or elastomer safety on its website, making independent verification of additives difficult.
How it compares in its category
Fluoroelastomer sport bands occupy the mid-tier for safety transparency. They are more chemically inert than silicone (which can shed oligomers under heat and UV) and less documented than premium bands with formal eco-certifications. Apple's official fluoroelastomer bands and established brands like Nomad offer comparable materials but with slightly better disclosure practices. Spigen's price point and material choice are typical for third-party alternatives.
If you buy it
Rinse the band with fresh water after sweat or salt exposure to prevent material degradation and skin irritation. Avoid prolonged contact with direct sunlight or temperatures above 60C (140F), as fluoroelastomer can harden over time. Replace the band if visible cracking, discoloration, or a chemical smell develops. Store in a cool, dry place when not in use to extend the band's lifespan.
