Bests & Worsts Reviews from Amazon

LOVE it. Very comfortable, great under the bike helmet for crisp morning rides or just wearing to and from the vehicle going to work. I'll never go back to acrylic. I have the orange and white versions. I love both equally well. I find them comfortable anywhere from very cold all the way up to 50s and 60s. Wool keeps the sweat smell away nicely even after exercising on long hikes or rides. I have used them numerous times in the mountains of CO and all winter in Iowa.
