Arc'teryx Eon SLW T-Shirt - Short Sleeve - Women's - $44.48

The beauty of the merino wool in the Arc'teryx Women's Eon SLW Short-Sleeve T-Shirt is that it manages to breathe for comfort in warmer weather, and keep you warm and dry when you layer up in cooler weather. This makes it suitable not only for three-season trail runs and hikes, but for high-output winter excursions. - $44.48
