Smartwool Merino 250 Baselayer Pattern Women's 1/4 Zip Top

Smartwool's best selling and warmest base layer just got a little more refined with an improved fit, chafe-free seam construction and panels that offer more comfort with a pack.

This slim fit, 100% Merino wool 1/4 Zip Top offers breathable warmth, wicks sweat away from the body, and provides next to skin comfort. The heavier, soft, 100% Merino wool fabric is thinner and softer than regular wool, making it more comfortable to wear next to skin. It works to keep your body at a stable temperature - when it's cold outside, the natural crimps and bends in its fibres trap air, insulating you. When it's warm outside, it transports sweat quickly away from the skin, helping to keep you cool and dry. Merino wool transports sweat and moisture away from the skin as a vapour. Merino fibres are inherently porous, composed of little plates that moisture vapour can get in between-meaning you're not left feeling wet, cold, and clammy after a workout. Merino wool is unique in that it absorbs odour caused by bacteria, trapping their smell and keeping them from building up. The crew neck fit has set-in sleeves but this does not restrict your movement, with shoulder panels eliminating top shoulder seams. The back body seam wraps to the front of the top, for a body-enhancing, flattering and comfortable fit. Flatlock seams used throughout the top are designed to minimise chafing and skin irritation, making this base layer as comfortable as possible. The 1/4 zip makes this top perfect for layering but also puts you in complete temperature control. Simply zip up to retain all-important body heat, or zip down for some extra ventilation when things heat up.
