TYR Hi-Vis Warmwear Swim Cap — Flour Yellow PU-Coated Polyester, One-Size for Visibility & Warmth

The TYR Hi-Vis Warmwear Swim Cap in flour yellow is a one-size swim cap engineered to boost open-water visibility while helping retain heat for more comfortable swims.

Designed for swimmers who spend time in cooler outdoor waters, this cap combines a vivid color for safety with a PU-coated elastic polyester construction that reduces heat loss compared with standard thin caps. It covers hair to reduce drag and sits comfortably on the head, delivering both functional performance and simple, dependable protection during training sessions or recreational swims.

How does this cap improve safety in open water?

The flour yellow hue is chosen to stand out against waves, low light and varied backgrounds, making it easier for paddlers, boats and fellow swimmers to spot you. Increased visibility helps others identify your location quickly without relying on additional accessories.

• Bright flour yellow color for maximum contrast in natural settings
• One-size design fits most adult head shapes for consistent visibility
• Simple silhouette avoids reflective strips that can snag or peel

Will this cap help me stay warmer in cool water?

The cap's elastic polyester base is coated with PU to create a thicker barrier than many fabric-only caps, which helps slow heat loss around the head. While not a substitute for a neoprene swim hood, its construction offers measurable warmth for athletes who need extra comfort on chilly days.

• PU-coated elastic polyester retains more body heat than uncoated fabric
• Snug one-size fit minimizes water circulation under the cap
• Lightweight warmth without the bulk of rubber or neoprene

How does the cap affect swim performance and hair protection?

This cap covers hair to reduce drag and provides a smoother surface in the water, helping maintain speed and streamline body position. The textile construction is gentle on hair compared with latex, and the elastic fit secures the cap without excessive tension.

• Covers hair to lower resistance and maintain hydrodynamics
• Elastic polyester is less likely to pull or tangle hair than latex
• PU coating gives a sleeker outer surface for smoother gliding

How do I care for and fit the TYR Hi-Vis Warmwear Cap?

Put the cap on by stretching around the widest point of your head and pulling down evenly to avoid overstretching the seams. Rinse with fresh water after open-water swims, air-dry out of direct sunlight, and avoid sharp objects to preserve the PU coating.

• Stretch gently over the head to maintain elasticity
• Rinse after use and air-dry to prolong material life
• Store flat or loose to prevent permanent deformation

Who is this for: The TYR Hi-Vis Warmwear Swim Cap is aimed at open-water swimmers, triathletes and outdoor training enthusiasts who want enhanced visibility plus extra thermal protection without the heft of a hood. It's suitable for adults seeking a one-size cap that balances safety, modest warmth and hair protection during colder-season swims or variable light conditions.
