Polar · Water-Resistant Smart Rings & Bands
Polar Silicone Watch Bands for Polar Smartwatch Waterproof Strap Camo Orange / 20mm
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes silicone, 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.
Skin sensitization from pigments or residual monomers
Camo colorants are added to silicone; if the band is poorly cured or contains residual uncrosslinked oligomers, rare allergic contact dermatitis can occur. This is not unique to Polar but is a low-frequency risk across all dyed silicone wearables; no specific incidents reported for this model.
Degradation and surface cracking over time
Silicone bands can become stiff, discolored, or develop micro-cracks after 18-36 months of daily use and UV exposure. Cracked surfaces may harbor bacteria or cause minor skin irritation but do not shed microplastics or leach chemicals in silicone's case.
Bacterial or fungal growth in seams and attachment points
Moisture and sweat can accumulate in the recessed areas where the band connects to the watch case. Regular rinsing and drying mitigate this; no treatment coating is described that would inhibit microbial growth.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Polar does not disclose pigment sourcing or heavy-metal testing for this band. Industrial-grade silicone pigments are typically cadmium-free and lead-free by modern standards, and no regulatory action or test data suggesting otherwise has been published for Polar bands.

What it's made of and why it matters
This band is made of silicone, a synthetic rubber polymer that does not contain the volatile organic compounds or leachable plasticizers common in other elastomers like PVC. Silicone is chemically inert at body temperature and does not degrade into harmful byproducts with normal wrist-contact use. The camo orange colorant is a pigment blend mixed into the silicone matrix during manufacturing; no separate coating or surface treatment is described, so there is no additional layer to delaminate or leach.
The brand's record and disclosure
Polar, a Finnish sports-watch manufacturer owned by Gorki Ventures (formerly Polar Electro), has not published public statements on PFAS or harmful chemical management specific to watch bands. The company holds ISO 13485 certification for medical device quality management, which implies some supply-chain oversight, but no third-party safety certifications or restricted substance disclosures have been found for this band model. No product recalls related to chemical safety have been established in public records for Polar silicone bands.
How it compares in its category
Silicone watch bands are among the lower-concern elastomeric options for wearables; they are preferred over PVC or TPE for skin contact because phthalates and BPA are not materials linked to silicone. Most competitor bands (Apple, Fitbit, Garmin) also use silicone for premium comfort straps. Polar's band material is consistent with industry standard, with no known cost-cutting or inferior formulation reported.
If you buy it
Rinse the band in cool water and mild soap after sweating or salt-water exposure to prevent skin irritation and extend durability. Do not expose the band to sustained heat above 60°C (140°F) or direct sunlight for prolonged periods, as silicone can harden or discolor over time. Inspect the attachment points and surface for visible cracks, discoloration, or stiffening every 6-12 months; most silicone bands remain flexible for 2-3 years with regular care. Replace if the band tears, loses flexibility, or begins to flake.
