I love this hat for underneath a climbing helmet. The dome section of the hat is thin enough to fit nicely under the suspension system of a helmet, but provides enough insulation to keep your head warm. The lower band has extra insulation, with even more insulation around the ears. A lot of my work and play requires the use of a helmet, often in cold weather. This is my go to hat for those conditions. I've also used it as an extra layer of insulation under a balaclava during extreme conditions.
