Rab’s lightest softshell, the Men’s Borealis Jacket balances stretch, wind resistance, and breathability for no-fuss protection when you’re climbing. This purpose-built piece also boasts UPF 50+ sun protection to keep you safe from the sun’s harmful rays, while the sleek fit, harness-compatible pockets, and under-helmet hood add on-wall convenience. The left chest pocket doubles as a stuff sack that you can clip onto your harness so you never have to leave the ground unprepared.
