Description ***Sitka&';s Standard Fit is designed to accommodate layering for added versatility across early-to-late season conditions. We recommend ordering this true-to-size.*** The Sitka Microdown Pant delivers lightweight, packable insulation for unpredictable cold-weather conditions in the mountains or around camp. 700-fill ExpeDRY treated down helps maintain warmth in high humidity, while the 27D polyester shell sheds light precipitation without adding unnecessary bulk. Full-length versatility comes from 7/8 side zippers that make the pants easy to pull on and off over boots, and the low-profile elastic waistband keeps layering simple and comfortable.
