Mizuno Rainfit Golf Gloves
Golf gloves with water-repellent coating; PFAS details unknown.
Mizuno Rainfit gloves use waterproof treatment typical of golf gloves, but Mizuno discloses no PFAS policy or testing. Water-repellent coatings often contain PFAS; lack of transparency raises concern.

The full breakdown
What it's made of and why it matters
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.
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.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
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-releasing resins in synthetic leather backing
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.
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 safe use.
Azo dyes or heavy metals in synthetic leather pigments
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.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
