This is a light jacket for fair weather snowshoeing, climbing, or hiking. Moving hard and fast through the mountains creates plenty of body heat and the lightweight Coreloft™ insulation helps trap the warm air you generate close to the body. Ideally worn as a midlayer, be sure to throw your hardshell over top when the elements fall upon your adventure. The side panels are all about breathability: made from Polartec® Power Stretch® with Hardface™ technology to give your sweaty pits plenty of cool-factor. When your body heat rises, shed the hoody from your back and compress it down into the arm sleeve to create a neat little package you can stuff into your backpack. The trim fit keeps it close to your body for a stellar look with stretch knit cuffs that wrap closely around your wrists for comfort and draft blocking.
