EZ Hydro-Glide®

The EZ Hydro-Glide® is a patent-pending insert designed to improve open-water safety by helping regulate head temperature in both cold and warm conditions, reduces cold & hot water shock by helping to regulate your body temperature. .

Positioned in the middle of the forehead, it helps reduce the effects of hot and cold water shock, lowers thermal stress and supports safer, more controlled breathing during open-water swims.

Its low-profile lattice structure is lightweight, non-buoyant, comfortable to wear, and designed to fit seamlessly inside most swim caps.

The EZ Hydro-Glide® project brought EZ Gains® and Ultra Cool Tech together with a shared mission: build a cooling system that genuinely improves swimmer comfort and performance in warm water.

EZ Gains® had the vision for a smarter accessory; Ultra Cool Tech contributed deep expertise in Active Cooling engineering, material science, and athlete‑tested thermal solutions. Working side‑by‑side, the teams explored different Phase Change Material (PCM) formulations, tested heat‑absorption profiles, and refined the integration so the cooling pack fits seamlessly into the Hydro-Glide without adding bulk or disrupting hydrodynamics.

Ultra Cool Tech’s background in developing cooling systems for endurance sports helped shape a solution that doesn’t just feel cold at the start — it manages heat consistently, delaying fatigue and helping swimmers maintain form for longer.The result is a clean, intuitive accessory powered by real engineering.

This collaboration blends EZ Gains® product innovation with Ultra Cool Tech’s cooling expertise to deliver a meaningful performance advantage where swimmers need it most.
