SmartWool Microweight Zip-Top - Women's - $84.95

The SmartWool Womens NTS Microweight Zip-Top does all kinds of cool stuff to keep you cool in the summer, warm in the winter, and odorless all year long. The long sleeves help your body regulate its temperature more efficiently and help protect your arms from harmful UV rays. The NTS's tall collar forms a gasket to keep out drafts and snow on powder days, and the 1/4-zip design allows you to dump heat quickly and makes the NTS easier to get into and out of. Most importantly, Smartwool's merino wool fabric pulls moisture away from your body to keep you dry and comfortable while it fights odor. - $84.95
