these are hairbands more than headbands [SEP] generally silicone strips or bars as the description reads are there to keep hairbands from slipping off of hair on sweat they are going to block your pores where the sweat needs to come out and then slip around from all the sweat moisture that is accumulated underneath them these are thin and do not absorb much beyond light perspiration they do not wick away any substantial amount of sweat fast enough the material is soft stretchy and comfortable but they do not perform the way i need them to i am not happy with my purchase
