A low-profile four-panel cap built for boaters and hot-weather days. The soft foam bill is the key feature—it's crushable, packs down small, and floats, so it's a good one to wear under a helmet or stuff in a bag without worrying about a stiff brim. Mesh side panels move air and drain water, the black underbill cuts glare, and KAVU's nylon webbing strap adjusts the fit. The water-resistant fabric dries fast.
