Working up a sweat is one reason we work out an exercise but sweat in the eyes is never fun when on a long summer bike ride. This is where the SweatHawg comes in. It is a helmet liner that is made in Oregon of Hydo-phillic fabric from Germany and can reportedly absorb 10 times its weight in water, and which can be rung out if it gets too saturated. It can keep the sweat out of the eyes and thus help on those hot summer days!
