Our Cooper Lake Trunks are ideal for fishing, cooling off in mountain lakes, or any action in the water. The lightweight nylon fabric is treated to minimize water absorption, so they dry faster. The elastic waistband secures with a drawstring. One-inch slits on the outer hems help provide ease of motion. The rear pocket zips closed for security and features an elastic cord loop to secure a keyring. Mesh front pocket bags drain instantly. Treated for resistance to cholorine.
