XTM Heater Merino Outdoor Crew Socks

You loved the OG Heater Sock – thick, toasty, and tough as nails. So we took everything that made it a legend and gave it an outdoor upgrade. Say hello to the Heater Outdoor Crew Sock – the all-terrain version of your winter favourite. Made with a powerhouse blend of 40% Aussie Merino wool for warmth, acrylic for durability, and just the right stretch to stay put all day. Full terry cushioning and a seamless toe keep the comfort dialled high, while the comfort band stops any annoying slip-downs mid-hike, mid-ski, or mid-Netflix binge (no judgment). Unisex Sizing M US 6-10 L US 11-14
