We have all been there, that stinging feeling of sweat getting in our eyes. The Halo 2 headband will keep sweat out of your eyes with its SweatBlock Seal. This technology uses silicone channels to create a barrier that channels sweat back and away from the eyes. The Dryline fabric absorbs sweat and wicks moisture to the surface where it can dry quickly. With their pull over design they stay well in place during any activity and will never lose shape or stretch out. Works great under any type of helmet.
