An all-season favourite, the Merino 150 long sleeve can be sported as a baselayer in the fall and as a single layer when summer backpacking calls. Using core spun technology, Smartwool wrapped merino around a nylon core for added durability, without losing the benefits of ultra-soft merino. The raglan sleeves eliminate shoulder seams for perfect comfort under a pack, and smooth merrow stitching wraps from side to front to keep you looking as good as you feel.
