"What Our Gearhead® Experts Are Saying: ""This balaclava has it all—perfect fit under a helmet, no freezing, and the hinge makes it super versatile. I love how breathable it is on the move, and the TREO liner feels insanely soft, even on the coldest mornings."" The BlackStrap Sock Hood Balaclava is our go-to for staying warm, dry, and ready when the mountains are calling. Engineered for high-output snow pursuits, it’s built with a dual-layer design that balances protection and breathability, adapting as conditions and effort levels change. The PERFA outer shell blocks wind while offering unrestricted movement with four-way stretch, and the plush TREO liner is freeze- and abrasion-resistant for next-to-skin comfort. A contoured flare neck seals smoothly over layers, while the dual-layer hinge lets us pull up for warmth or down for airflow. Whether lapping chairlifts, breaking trail, or chasing sledlines, the Sock Hood delivers ergonomic comfort and technical coverage without compromise."
