What Our Gearhead(R) Experts Are Saying: "I wore the Dotknit AMK Tight under shell pants for a ski mountaineering day, and they kept me warm and dry the entire time. The DotKnit fabric doesn't trap sweat like typical baselayers-it moves moisture out fast. Super comfortable for long days in the harness or touring setup." Built for missions that demand performance in frigid, high-output environments, The North Face Summit Dotknit AMK Tight is our go-to alpine baselayer. Using DotKnit Thermal fabric with FlashDry-Pro(TM), it actively moves moisture away from our skin to regulate heat and keep us dry-even on high-effort approaches or technical climbs. The articulated fit, gusseted crotch, and soft waistband make it easy to move comfortably under shell pants or a harness. Built with 100% recycled polyester and part of The North Face's Circular Design collection, it's an alpine essential that combines long-lasting durability with next-level performance and sustainability. Whether we're climbing frozen couloirs or skinning through cold ridgelines, this tight keeps our core dry, warm, and ready.
