Mountain Hardwear: Spirit SL 32 Degree Sleeping Bag

Maybe shave down the rack, maybe carry less food, but don't ditch the R2 Vest for climbs where core warmth matters as much as weight. Its unique variable-knit polyester ensures optimal breathability, moisture-management, and warmth for low-bulk core insulation that's especially effective when worn under a shell. Stretchy R1® fabric (made with 60% recycled polyester) lines the inner collar for next-to-skin comfort. The vest has an easy-to-use front zipper, welded-in zippered handwarmer pockets and forward-set shoulder seams for comfort with a pack. Recyclable through the Common Threads Recycling Program.
