Smartwool 1/4 zip 100% Merino wool size X-small total length: 21.5" pit-to-pit: 15" This is the midweight or 250g base layer from Smartwool. Great for pairing with jeans or wearing as an active layer! No flaws, only worn a few times. This is a brown and white design - the last photo shows the color best, but let me know if you have any questions :)
