SmartWool Merino 150 Long Sleeve Baselayer Women's

It's almost impossible not to get sweaty when you're running from a pack of marmots that are hungry for your trail mix, but the Women's Merino 150 Long Sleeve Baselayer Top is just the ticket. Smartwool made it extra tough by combining its famous merino wool with a hint of synthetic, and wove the 150 with a flattering cut and seams that won't cause discomfort when you're sprinting away from 30 fat and not so cuddly alpine rodents.
