Smartwool Intraknit Merino Tech 1/4-Zip Top - Women's Deep Navy, M

Smartwool has always slayed its baselayers, and the Intraknit Merino Tech 1/4-Zip Top has upped its insulation game with its novel knitting of merino wool and synthetic fibers. This mid-layer top works by layering insulation panels with targeted mesh venting panels to keep us warm and release extra heat when we're working up a sweat on the trail or slope. That body mapping helps to regulate our body temperature and moisture levels when we're active in chilly conditions, and the stripes on the sleeves add some style to our winter layering system.
