What Mizuno Golf Rainfit Gloves Pair Black is made of, ingredients and materials
These gloves use polyurethane-based synthetic leather, which is engineered to mimic leather durability while offering water resistance. The water-repellent finish (water-repellent coating) is the critical unknown, most golf-glove water-repellent coating treatments historically relied on fluorinated compounds (PFAS) to achieve durable water beading, though some brands have moved to non-fluorinated alternatives without public announcement. Polyurethane itself is stable during normal wear but can degrade under heat or UV, potentially releasing volatile organic compounds (VOCs) in poorly formulated products.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Water-repellent coating finish composition is undisclosed by Mizuno. Golf gloves historically use PFAS-based Teflon-family coating; no public statement confirms this glove uses alternatives. Risk is dermal absorption and environmental persistence if coating sheds or glove is discarded.
Source, ATSDR ↗Polyurethane thermal degradation and VOC release
Synthetic leather can release volatile organics if exposed to prolonged heat (sweat in hot weather, machine washing, or storage near heat sources). No formulation data available to assess Mizuno's specific polyurethane stability or additive package.
Microplastic shedding from coating or backing
Water-repellent coating coatings and polyurethane backing can shed microparticles during wear and washing. Significance is low for personal health (hand exposure) but relevant for environmental persistence if the product ends up in landfill or marine environments.
What’s reassuring
Formaldehyde / VOCs
No documented formaldehyde issues specific to Mizuno gloves; polyurethane-based synthetics typically use less formaldehyde than cotton-polyester blends, but adhesives and backing resins may contain urea-formaldehyde. No recalls or test results on record.
Source, ATSDR ↗Heavy metals
Black synthetic leather may use carbon black or organic azo dyes; neither is flagged as problematic in golf gloves, and migration to skin during normal wear is unlikely given the polyurethane barrier. No incidents reported for this product or brand.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Mizuno is a major Japanese sportswear manufacturer with no public record of independent chemical testing, PFAS commitments, or transparency in apparel safety reporting as of available records. The company does not appear to have signed the Zero Discharge of Hazardous Chemicals (ZDHC) initiative or published restricted substance lists for gloves, leaving the water-repellent coating formulation entirely opaque. No recalls or documented safety incidents specific to Mizuno golf gloves are known, but the silence on fluorinated chemistry is the concern.
How it compares in its category
Golf gloves occupy a niche where water resistance is marketed as essential, making them prime candidates for PFAS-heavy coatings. Brands like Callaway, TaylorMade, and FootJoy use similar synthetic leather with undisclosed water-repellent coating finishes, meaning this product is typical, not outlier. A small number of premium gloves now offer PFAS-free water resistance (e.g., some wool or organic cotton blends), but synthetic leather remains the category standard. Mizuno's lack of transparency is consistent with broader golf-apparel practice but not better.
If you buy it
Wash hands after removing gloves to minimize skin contact with any coating residue; do not machine wash or expose to heat above 40C, which may accelerate polyurethane breakdown. Store in cool, dry conditions and replace after visible cracking, peeling, or loss of water beading (typically 1-2 seasons of regular use). If PFAS exposure is a personal concern, contact Mizuno directly to request water-repellent coating formulation details; lack of response suggests conventional fluorinated chemistry. Consider rotating with an untreated glove or one from a brand with published non-PFAS coatings on days when water resistance is non-critical.
