When you're limited on pack space, wouldn't it be great to have an ultra-light shell that packed down, making it easy to stash away? 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 Jacket is the perfect layer for whatever Mother Nature throws your way.
