What Mizuno Rainfit Golf Gloves is made of, ingredients and materials
Mizuno Rainfit gloves use synthetic leather or polyurethane with a water-repellent treatment applied to the surface. Polyurethane itself is generally stable, but the water-repellent finish, likely a fluorochemical or silicone-based coating, is where chemical concern arises. This coating degrades with sweat, UV exposure, and friction, potentially releasing particles or residues into skin contact over time. No public data confirms what specific repellent chemistry Mizuno uses or its durability profile.
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.
Water-repellent coating composition (fluorochemical or silicone)
The repellent finish is not disclosed by Mizuno. If fluorinated (PFAS-based), it poses respiratory and dermal hazard during manufacturing and slow leaching during wear; silicone alternatives avoid PFAS but lack long-term safety data. Degradation over time increases particle/residue contact with skin.
Formaldehyde / VOCs
Polyurethane synthetic leather may incorporate formaldehyde-based binders or hardening agents to improve durability and water resistance. No specific testing of Mizuno Rainfit for formaldehyde is published; this is a category-wide concern for synthetic athletic gloves, though typically at low levels due to regulatory limits in major markets.
Source, ATSDR ↗Microplastic shedding from degraded synthetic coating
As the water-repellent or polyurethane surface ages and cracks under sweat and friction, microfibers and coating particles may shed into skin or be inhaled. No specific study of Mizuno gloves exists, but synthetic athletic gear shedding is an emerging concern in textiles generally.
Fungal or bacterial growth in moisture-trapping synthetic material
Polyurethane retains sweat and moisture longer than natural leather, creating conditions for microbial colonization if gloves are not dried promptly. This can cause odor, skin irritation, or infection rather than chemical hazard, but is relevant to concerned use.
What’s reassuring
Heavy metals
Mizuno does not disclose dye chemistry or heavy metal testing results for this product. Synthetic leather typically uses azo dyes and may contain antimony or cadmium from pigment production; no recalls or complaints specific to Rainfit gloves are recorded, suggesting acceptable baseline compliance with apparel safety limits.

The brand's record and disclosure
Mizuno has not made public commitments to phasing out PFAS or other hazardous chemistries in apparel, and does not disclose water-repellent treatment details on product labels or sustainability reports. The company maintains certification for performance sports products but has not engaged in the transparency benchmarking that leading outdoor/athletic brands now do (e.g., detailed chemical inventories, third-party testing). No recalls or safety controversies specific to this glove line are documented.
How it compares in its category
Golf gloves are generally lower-risk than heavy outerwear because contact is localized to hands and duration is intermittent. Water-repellent treatments are standard across brands (Callaway, FootJoy, TaylorMade use similar finishes), so Rainfit is not unusual in this regard. Compared to fluorinated water-repellent textiles in rain jackets or waterproof pants, golf gloves pose lower systemic exposure risk due to smaller surface area and lower skin contact intensity, though hand sweat increases local chemical migration.
If you buy it
Wash gloves by hand in cool water after use to remove sweat and extend the water-repellent coating life; avoid machine washing and hot water, which accelerate coating breakdown. Replace gloves every 12-24 months depending on frequency of play, as degrading coating may shed microparticles and lose water repellency function. If skin irritation, rash, or odor develops, discontinue use and rinse hands thoroughly; this may signal coating breakdown or mold growth in the synthetic material. Store in a dry place to prevent bacterial or fungal colonization of the moisture-trapping synthetic leather.
