Our new Switchback line offers comfort and protection in a mid-weight base layer that has all the benefits of our Pinnacle base layers but less weight for more moderate temps or those who "run hot". Switchback Ushoods include UPF50+ sun safety; antimicrobial protection; and moisture-wicking, breathable fabric with a 4-way stretch that allows for full performance. Also, in addition to our signature mask/hood and thumb holes, the Switchback line is the first to feature a ponytail opening!
Sizing Tip: Size down if using it as a base layer against the skin in order to contain as much body heat as possible. Go with your normal size if wearing it as a cozy shirt or top layer.
