The Scout Air is created using an innovative in-molding technique that combines the outer Tri-Matrix composite shell (woven aramid, glass and carbon fibers) with the internal EPS foam liner. The result is an extremely lightweight helmet that has you covered with both DOT and the European ECE certification requirements. Weighing in at a feathery 900 grams, it almost disappears on your head. For each helmet size BELL is working with different sized shells and linings, which make this helmet very compact in appearance. The usual balloon shape common with DOT / ECE certified helmets, especially with small size numbers, is thus avoided.
