Women's functional T-shirt Smartwool W MERINO SPORT 250 LS CREW. Don't let colder temps keep you from getting out for a run/ski/snowshoe. Our Women's Merino Sport 250 Long Sleeve Crew is made of a warmer Merino/poly blend to help move moisture, dry quickly, and hold its shape during high-sweat activities in colder weather. Gender-specific, body-mapped panels of lighter fabric provide additional breathability while snaps on the cuff let you roll up your sleeves, secure them, and get back to your activity.Material: 56% Merino Wool, 44% Polyester
