Speedo Men`s Hydrovent Short Uv Protection Water

Azo dyes

Polyester/nylon blends can be dyed with azo-based colorants. No recalls or public test results document azo dye concerns for Speedo swim shorts. If present, restricted azo dyes are banned in EU textiles, but product origin and supply chain transparency are not published.

Antimony in polyester

Polyester production sometimes uses antimony trioxide as a catalyst. Antimony is a confirmed skin irritant and potential carcinogen at high exposure. Finished polyester fabric typically contains minimal residual antimony if properly processed, but Speedo does not disclose manufacturing controls or testing. Direct skin contact during wear poses low risk; concern is primarily occupational or industr

water-repellent coating finish off-gassing (volatile organic compounds)

Water-repellent coatings can emit low levels of volatile organics, particularly on first wear or if stored in warm conditions. This is typically minimal and odor-based rather than systemic toxicity. Air out the shorts before first wear to reduce any chemical smell.

Degradation and microfiber shedding

Polyester/nylon blends shed microfibers during washing and wear, especially with friction or poor-quality stitching. This product's fiber shedding rate is not published. Microplastics themselves are not acutely toxic to the wearer, but shedding contributes to aquatic plastic pollution, particularly from frequent washers of swim apparel.

Formaldehyde in resins or finishes

Some apparel finishes use formaldehyde-releasing resins for wrinkle resistance or crease-setting. Swim shorts typically do not require heavy formaldehyde finishing. No public test data or recalls document this hazard for Speedo products, but full ingredient disclosure is absent.
