The Bang Buster Headband!
It rocks. Seriously. I learned of it through my awesome running and spin instructor friend Sheri Matthews over at https://www.facebook.com/SheriLifeFitness. She wears them when she teaches spin and I was curious. She swears by them and told me to check them out.
I headed down to my local Lululemon in Bethesda and bought a lime green and a black one. I have been wearing them for the last two weeks and they are amazing. They stay on, just like the Heads Up Headbands, but because they are so large, I actually wear them a little lower so part of the material covers a bit of my forehead. It catches the sweat and I have less sweat dripping into my eyes while teaching. Also since it's larger, it keeps my hair flat. My hair tends to frizz up when it gets super sweaty in a hot spin room. This helps tame it! If I need to tame frizzy hair on my runs, I used to use a running hat, but in spin, I want my participants to be able to see my face clearly, so this headband fits the bill!
