We used our tried-and-true HELLY TECH® Professional system to make a 5-layer, sturdy sailing jacket strong enough for the pros. It’s become a trusted favorite among many offshore pro sailors! Fully waterproof, windproof and breathable, it’s also designed with mobility in mind. Articulated sleeves give you optimal freedom of movement, while an adjustable hem, waist and hood let you customize the fit. We added a comfortable, high collar, and packable face mast for extra protection from the elements .
