Motorola Moto Sailcloth Quick Release Waterproof Nylon Watch Band
Skip; waterproof nylon likely water-repellent coating-treated with uncertain PFAS risk.
Motorola doesn't reveal PFAS or coating details for this nylon watch band. Waterproof nylon typically requires water-repellent coating treatment, often PFAS-based.

What Motorola Moto Sailcloth Quick Release is made of, ingredients and materials
This band is nylon, a synthetic polyamide fiber, with a waterproof coating applied to the surface. Waterproofing on textiles is typically achieved through water-repellent coating (water-repellent coating) finishes, which in consumer nylon products are often fluorine-based (PFAS) or, less commonly, silicone or wax alternatives. Motorola has not disclosed which chemistry is used here. Nylon itself is chemically stable in normal wear, but the coating's composition and durability directly affect your exposure risk during extended skin contact.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Coating degradation and microplastic shedding
Repeated flexing, sweat exposure, and UV light can cause the waterproof coating to crack and shed microscopic particles. If the water-repellent coating is synthetic polymer or Teflon-family coating-based, flaking could introduce microplastics into skin contact or the environment.
Allergen potential from dyes or finishes
Direct contact with nylon in warm, moist conditions (wrist sweat) can increase skin sensitivity to residual dyes or finishing chemicals, though nylon itself is not a common allergen. No Motorola-specific allergic reaction reports located.
Bacterial/fungal growth under retained moisture
If the waterproof coating traps moisture against the skin or the band is not dried thoroughly after water exposure, warm, damp conditions favor microbial growth, independent of the nylon or coating chemistry.
What’s reassuring
Azo dyes (colorfast synthetic dyes)
No recalls or reported dye-related issues for Motorola nylon bands on record. Commercial nylon watch bands typically use acid dyes or disperse dyes, which are generally regulated; however, composition specifics are not disclosed.
Formaldehyde / VOCs
Nylon bands are not typically finished with formaldehyde-based resins (common in cotton), but waterproof coatings may contain trace formaldehyde donors; no test data available for this specific product.

The brand's record and disclosure
Motorola (owned by Lenovo) produces consumer electronics and accessories but has no publicly available textile safety certifications or PFAS disclosure policies for watch bands. The company does not list restricted chemical lists or water-repellent coating treatment specifications on product pages or sustainability reports. This silence on material chemistry is a red flag for a wearable product in direct skin contact, especially one marketed as waterproof where coating integrity matters.
How it compares in its category
Watch bands span from leather to silicone to woven nylon. Woven nylon bands are durable and affordable but require waterproofing to resist sweat and moisture. Many mainstream brands (Apple, Samsung) either avoid nylon or use proprietary coatings without public transparency. Motorola's offering is mid-tier, more robust than fabric but less transparent than premium alternatives that disclose PFAS-free water-repellent coating or use proven silicone-based finishes.
If you buy it
Wash the band regularly with mild soap and water, separate from the watch body, to reduce accumulation of sweat and bacteria under the coating. Do not machine wash or bleach, which can degrade the waterproof layer. Replace the band if you notice flaking, peeling, or discoloration of the coating, as this indicates breakdown of the protective barrier. Given the unknown coating chemistry, consider rotating with a second non-waterproof band (cotton or untreated nylon) to limit continuous skin exposure.
