The Men’s Borealis is Rab's lightest Matrix softshell jacket, providing wind resistance & high levels of breathability in a packable design. It makes a great layer for climbers, thanks to the stretchy fabric that enables complete freedom of movement. Plus, the low-profile hood fits comfortably under a hood. The zipped chest pockets provide secure storage that is accessible while you’re wearing a harness. When you don’t need to wear it, the Borealis stows easily into the left pocket. Lightweight Lycra bound cuffs & hem are comfortable, working alongside the half hem drawcord to seal out cool winds.
