The Icebreaker 150 Zone Legless Pants are designed for the outdoor enthusiast that's trudging through the skintrack to reach the summit or spending long days at the resort. Made with a merino wool, nylon, and Lycra blend fabric, this baselayer pant offers natural wicking and anti-odor properties, with added durability and stretch for additional performance. Merino woo mesh panels offer extra breathability to regulate your temperature, and flatlock seams prevent chafing for all-day comfort.
