Warm, lightweight and packable, the Big Agnes Upper Slide SL 20 sleeping bag takes synthetic-insulated snoozing to a new level, with downlike loft and compressible heat retention.

  • Features

    • Traditional mummy shape reduces weight and increases thermal value
    • Nylon shell fabric with a durable water repellent (DWR) finish and minimal exterior stitching sloughs off light moisture
    • 80% recycled PrimaLoft® Black Hi-Loft Ultra insulation provides downlike warmth, loft and compressibility
    • Accordionlike construction maintains the insulation's vertical loft while keeping heat trapped against the body
    • Oversized interior provides wiggle room; vaulted footbox provides additional loft and warmth
    • Low-profile cordlock lets you un-cinch the hood with just one hand
    • Layered offset quilting on bottom prevents cold spots and remains soft and resilient even after sustained compression
    • Interior fabric loops for sleeping bag liners; exterior loops for hang drying or storage
    • 70 in. (178 cm) YKK #5 antisnag locking zipper (regular and long)
    • No-draft tube along the zipper and no-draft collar prevents heat loss
    • Mesh storage sack and nylon stuff sack included
    • Part of the 1101 Collection inspired by the iconic Continental Divide Trail (CDT), a 3,000 mi. trail from Canada to Mexico that traverses 5 states and tops out at 14,000 ft.
    • Big Agnes will donate a portion of 1101 Collection sales to the Continental Divide Trail Coalition
