Review on OutdoorEssentials Skull Helmet Liner Running Outdoor Recreation by Travis Rogers

I use this skullcap to sleep. I keep the temperature in the bedroom at 63 and sometimes I get a cold head. I wear a CPAP mask with a headpiece that also slides smoothly over the cap. Now I have the perfect setup. I love that there were 2 in the pack and they are soft and fit very well. They're better than the under armor I used to buy at a much higher price, but they stretched too easily and wouldn't stay tight after a few months of use. I will definitely buy these again!
