Misfit Vapor Mis7000 50m Jet Black Case W/ Black Sport Strap
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic case, elastomer sport 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 strap composition and degradation
Sport strap material (silicone, TPE, or rubber) is not specified by Misfit. Standard elastomers do not off-gas significantly at body temperature, but quality and phthalate content vary by supplier; no third-party testing is published for this product.
Bacterial growth on elastomer strap if unmaintained
Elastomer sport straps trap sweat and moisture in surface pores, creating conditions for bacterial and fungal proliferation if not cleaned regularly. This is a hygiene risk common to all sport watch bands, not unique to Misfit.
Case degradation under sustained heat or UV
Prolonged exposure to direct sunlight or hot environments may cause plastic embrittlement and microscopic cracking, potentially increasing leaching. No accelerated aging data is published by the brand.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Plastic case leaching from unspecified polymer
The rigid plastic case is not documented to leach BPA or other endocrine disruptors under normal wear conditions. Risk is minimal because the case is sealed and does not contact food or liquids, but polymer type remains undisclosed.
Heavy metals
No recalls or reports of cadmium, lead, or other toxic pigments in Misfit wearables exist. Black plastic dyes are typically carbon-based or organic, but the brand does not certify heavy metal limits.

What it's made of and why it matters
The Misfit Vapor case is rigid injection-molded plastic (polymer unspecified in public materials), paired with an elastomer sport strap typical of fitness tracker bands. Rigid plastic housings used in sealed electronics generally pose lower leaching risk than soft plastics in food contact, since they do not flex repeatedly or contact liquids intended for ingestion. The elastomer strap material is not detailed in available product specs; standard silicone or TPE sport straps do not typically off-gas volatile organic compounds (VOCs) at body temperature.
The brand's record and disclosure
Misfit (acquired by Fossil in 2015) does not publicly disclose material safety testing, heavy metal limits, or chemical management policies for wearables. No recalls, CPSC actions, or third-party safety certifications are on record for this model or product line. The brand offers no statement on BPA, phthalates, or elastomer composition, leaving material provenance opaque. This silence is typical for the fitness tracker category but limits independent verification of supply chain standards.
How it compares in its category
Fitness tracker cases occupy a middle ground, less scrutiny than children's products or food-contact cookware, but more consumer contact than many electronics. The Vapor's sealed rigid case design has fewer contact pathways than open-contact surfaces, and the 50 m water rating derives from sealing integrity rather than coating, which may reduce certain chemical exposure routes. Competitors (Fitbit, Garmin, Apple Watch) similarly avoid public material disclosures, making Misfit's transparency typical but not exceptional for the category.
If you buy it
Rinse the strap regularly with soap and water to remove sweat and prevent bacterial buildup in elastomer pores. Avoid prolonged exposure above 45-50°C (113-122°F), as the case and strap may degrade and leach more readily at elevated temperatures. Replace the sport strap every 12-18 months if it shows discoloration, odor, or surface cracking. Do not immerse in hot water or solvents; cool water and mild detergent are sufficient for cleaning.
