The Rab Men’s Microlight Alpine Down Jacket has long been a mountain staple, but this year it’s boasting some exciting upgrades. This lightweight, packable, and impressively warm piece is now constructed from recycled fabric and insulated with lofty recycled down—but the updates don’t stop there. Rab used a combination of micro and nano baffling to level up the jacket’s warmth without adding weight or bulk. Of course, the Alpine Jacket still sports all the original beloved features, like harness-compatible pockets, a stiff hood brim to keep precip out of your eyes as you climb, and a regular fit that layers seamlessly. If you’re looking to add efficient toastiness to your alpine layering system, the search ends here.
