The Capitan, a helmet built for durability, has been updated. This helmet is environmentally friendly, using 30% recycled materials by weight. The shell is made of DuraPET and the internal padding is made of bamboo fiber. The shell has a two-piece construction, front and rear, that allows it to mold to the shape of your head. The foam is a combination of EPP and EPS, meeting UIAA requirements for side and rear protection. Ample openings allow for excellent ventilation.
