Knit with naturally odor-resistant merino wool, the SMARTWOOL® women's mid-weight long-sleeve baselayer top is form fitting without the squeeze of compression. Its moisture-wicking fabric makes it ideal for aerobic activities out in the bitter cold. Wear this crew-neck shirt solo and enjoy UPF 50+ sun protection; the shoulder panels eliminate the need for top shoulder seams so you can also wear it comfortably under another top.
