The Arva Balaclava classic is a great under helmet gaiter for skiing! The mix of Polyester and Elastane makes for a stretchy fit that works with most people while the "6 Fit" patter from arva hugs to the top of your head comfortably and wont slip around or constrict. The flat seams reduce chafing from them on your head while skiing. this is a great daily driver balaclava for under your helmet!
