Misfit · Waterproof Fitness Trackers & Cases
Misfit Vapor Smartwatch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes stainless steel case, elastomer 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
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 band degradation and particulate shedding
Elastomer bands degrade over years of UV exposure and thermal cycling; no test data on the Vapor's specific elastomer formulation is publicly available, so risk of microparticle release cannot be ruled out entirely, though it remains low under normal conditions.
Heavy metals
Stainless steel contains nickel and chromium; skin contact may trigger dermatitis in nickel-sensitive individuals. Misfit does not publish nickel-release data or hypoallergenic certification for the Vapor, though stainless steel grades used in wearables show lower nickel-release concern for most users.
Source, FDA ↗Bacterial colonization in band seams and case crevices
Elastomer bands and sealed cases can trap sweat and bacteria if not regularly cleaned; this is a maintenance issue rather than a manufacturing hazard, but contact dermatitis or skin infection is more likely in users who do not wash the device weekly.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Electronic components and solder/flux residue
The Vapor's internal circuit board is sealed and not in contact with skin or ingestion routes; no reports of lead solder or hazardous flux leakage into the user-facing surfaces are on record for this model.
Formaldehyde / VOCs
Elastomer bands used in fitness trackers do not typically off-gas formaldehyde or phthalates; Misfit has not published emission testing, but this category of material is not known to pose inhalation or dermal absorption risks in active wearables.

What it's made of and why it matters
The Misfit Vapor uses a stainless steel case, which is corrosion-resistant and does not leach heavy metals or degrade into food or skin under normal wear. The band is elastomer (synthetic rubber), a stable polymer that does not contain BPA, phthalates, or volatile organic compounds by design. Neither material requires a protective coating to achieve waterproofing, so there is no coating-related risk of flaking, lead, or cadmium exposure.
The brand's record and disclosure
Misfit (acquired by Fossil Group in 2015) has maintained low public visibility on chemical transparency and has not published a PFAS statement or safety certifications for wearables. No recalls, safety complaints, or toxicity findings specific to the Vapor smartwatch are on record. The brand does not advertise third-party testing (e.g., CPSIA, dermatest) for the device, but absence of disclosure does not indicate a known problem.
How it compares in its category
Stainless steel cases are standard in mid-range fitness trackers and carry lower contamination risk than painted or coated plastic alternatives. Elastomer bands are common in this category and avoid the formaldehyde resins and heavy-metal dyes sometimes found in fabric or treated leather straps. The Vapor's material choices place it in the lower concern half of smartwatch design, though it does not exceed competitors like Garmin or Apple in documented transparency.
If you buy it
Clean the band periodically with soap and water to prevent bacterial buildup in textile seams if present, though elastomer itself does not harbor pathogens. Avoid prolonged exposure to extreme heat (above 60 degrees Celsius) or direct sunlight for extended periods, which can degrade elastomer over decades. Replace the band if it becomes visibly cracked, peeling, or discolored, as elastomer degradation can expose wearers to worn particles. Do not rely on the device's water resistance rating beyond the stated depth; rinse with fresh water after salt water or chlorine exposure to extend seal life.
