Fitbit · Water-Resistant Smart Rings & Bands
Fitbit Ace LTE Courtside Active Band
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes elastomer/silicone band, 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
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Azo dyes and colorant safety
The band's color (Courtside implies a sports/team shade) may involve synthetic dyes. Fitbit does not disclose colorant restrictions. Azo dyes themselves are regulated in the EU but not formally banned in US cosmetics; sweat exposure is low risk, but very sensitive skin may warrant a patch test.
Heavy metals
Fitbit does not publish colorant heavy-metal limits specific to this band. US CPSC rules restrict lead and cadmium in children's products (Ace is marketed to kids); compliance is assumed but not independently verified on this product.
Source, FDA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Silicone leaching (general polymer concern)
Silicone does not leach BPA, phthalates, or other endocrine disruptors under normal body-temperature use. No adverse health reports linked to Fitbit silicone bands are on record.
Antimony in elastomer
Antimony is sometimes used as a catalyst in polyester synthesis, not in silicone elastomers. The Ace band is silicone, so antimony contamination is not a concern for this product.
Coating degradation and particulate shedding
No coating is documented on the Ace band; the material is bare silicone. Minimal particulate shedding is expected even after extended wear, and no recalls for silicone particle ingestion from Fitbit bands exist.
The full breakdown
What it's made of and why it matters
The Ace LTE Courtside band is elastomer/silicone, a synthetic rubber polymer that does not naturally contain PFAS, BPA, or phthalates in standard formulations. Silicone is inert at body temperature and does not leach into sweat or skin under normal wear. The material is lightweight and flexible, designed for all-day wrist contact on children and active users; no coating or surface treatment is documented, so degradation risk is low compared to enameled or laminated wearables.
The brand's record and disclosure
Fitbit (owned by Google since 2021) has not published a dedicated PFAS statement, and the Ace band carries no third-party chemical certification (e.g., OEKO-TEX, bluesign). However, no recalls or regulatory actions against Fitbit bands for chemical contamination are on record. The company does comply with US Consumer Product Safety Commission limits on lead and cadmium in children's products, which is relevant to the Ace LTE's youth focus.
How it compares in its category
Silicone bands present lower concern in the wearables category compared to polyurethane or nylon alternatives, which may contain flame retardants or azo dyes. Most competitor bands (Garmin, Apple Watch Sport Loop) also use silicone without disclosed PFAS. The Ace LTE's lack of a formal chemical certification is typical for this price tier; premium sports watches are more likely to carry independent testing.
If you buy it
Wash the band in cool to warm soapy water after heavy sweat or swimming; hot water or prolonged sun exposure is not necessary and offers no safety gain. Inspect annually for cracks or discoloration that might signal material breakdown, though silicone is durable for 2-3 years of daily wear. Replace immediately if the band tears or develops a strong chemical odor. No special storage is required; keep away from extreme heat (over 60°C) only to avoid unnecessary polymer fatigue.
