Why We Like The Ascent 1100 Sleeping Bag

The toastiest in its line, Rab's Ascent 1100 Down Sleeping Bag shields us from the mountain's bone-numbing temps. If moisture finds a way into our fabric hovel, the treated fill and exterior stop the wet from stealing our warmth.


  • Extra cozy sleeping bag for frigid nights on the trail
  • Compressible down insulation traps heat without the weight and heft
  • Recycled material blocks out wind and resists moisture
  • Zip baffle and 3D collar help seal in warmth
  • Wide mummy shape and angled foot box increase comfort
  • Internal zip pocket keeps your headlamp at the ready
  • Stuff sack and storage bag included for toting and stowing
