We optimized the silhouette of the classic baselayer top to make the Backcountry Cedars Rws Merino Lightweight Crew Baselayer Top incredibly comfortable for the active winter adventurer. From in-bounds shredding to skintrack ascents, this top's body-mirroring fit, articulated sleeves, and chafe-free seams keep us cruising toward our 100-day season goals. We thoughtfully selected a sporty wool blend made with content and Wool Standard-certified merino wool to be the best stewards we can while delivering top-notch quality and comfort.
