This balaclava lives up to it's name- Coolskin. Greatly improves comfort while riding with a full face helmet. It helps the helmet slip on easily over the ears. Protects the helmet lining from sweat and skin oil. I wear a Shoei X-11 (expensive) and the inside looks new after over 4000 miles of use. It is hot and humid around here and the Coolskin helps alot- it seems to pick-up and spread the air from the vents all around your head. Whenever someone complains about the comfort of their helmet I recomend Schampa.
