The Hydronaut Jacket by AFTCO is a rugged, highly functional rain jacket designed for extreme weather conditions on the water. Developed in collaboration with the AFTCO Pro Team, it is engineered to keep you reliably dry even in heavy rain. The 2-layer nylon outer shell, featuring a 30K waterproof membrane and a polyester lining, provides exceptional protection against the elements. The SpeedVent hood is designed to stay securely in place even in windy conditions and during movement. The elastic hem allows for a customizable fit to better keep out the cold and water. Practical chest and hand pockets provide secure storage, while a reinforced D-ring offers additional attachment options. The relaxed fit is intentionally roomy, allowing you to wear multiple layers underneath, making the jacket ideal for long and rugged outings.
