Western Mountaineering AlpinLite 20 Sleeping Bag

A thru-hiker workhorse built around 850-fill goose down in a continuous baffled mummy cut that rides at 1 lb 6 oz without giving up the warm-to-weight ratio down is famous for. The 20°F temperature rating lands the AlpinLite in three-season territory for the PCT, AT, and CDT — frosty shoulder-season nights stay comfortable without piling on the weight — and the breathable MicroLite XP shell sheds condensation on humid nights without the clamminess of a coated face fabric. The 5 ft 6 in / 6 ft 0 in length options cover most thru-hiker statures, the 64 in shoulder girth gives restless side sleepers real shoulder room, and the 1L stuff sack rides at the top of any ultralight pack.
