Heat built in. Calm on the surface.
Hydro Lab Heatwave is made for the warmer edge of watersports life. Early training, long coastal days, post-session recovery, and the hours when the body is still carrying the work. This release introduces a Light Feather colorway with bold red detailing, creating a sharper seasonal expression of the Hydro Lab uniform.
Constructed from structured heavyweight fleece, the hoodie delivers substantial comfort with a controlled, architectural drape. It is oversized by design, allowing unrestricted movement while holding its form through training cycles, travel days, and recovery hours.
