When you're limited on pack space, grab our Men's Merino Sport Ultra Light Vest. It easily packs down, making it easy to throw on when you just need a little extra warmth. Made with body-mapped panels of Merino Sport 150 mesh designed to help enhance breathability and temperature regulation, a DWR coating for wind and weather protection, and reflective elements for increased visibility in low-light conditions—our Men's Merino Sport Ultra Light Vest is the perfect layer for whatever Mother Nature throws your way.
