Light on the body. Sharp in presence.
The Heatwave Sweatpant is designed for the warmer season around water. Early training, long coastal days, post-session recovery, and travel between sessions. Rendered in Light Feather with bold red detailing, this release brings heat through contrast rather than excess.
The fabric is lighter than the previous Hydro Lab fleece, giving the sweatpant a more breathable summer feel while preserving the relaxed structure of a premium athletic silhouette. The cut is relaxed with an elastic waistband, adjustable drawcord, and athletic drape designed for recovery, movement, and daily wear.
