The warmest sleeping bag on the planet, the Snowy Owl has been the bag of choice for polar expeditions and high-altitude climbing since its inception. Our fully contoured design maintains full and even loft of the 900+ fill down in the head and shoulder regions. A second inner zipper running parallel to the main zip keeps the differential cut at a constant thickness and guarantees a tight, even draft seal. This system also serves as a backup in the event of a zipper failure; a deadly proposition at 60 below zero. The only complaint we hear about the Snowy Owl is that “it was too warm”. Well… that’s the idea. If you’re chasing the coldest temperatures in the world, this is the bag for you.

ES: Winter & Expedition. Pertex® Shield 15 denier with 40 denier rip-stop reinforcement fabric with water-resistant/ breathable coating with 3 Layer Pertex® Shield Air electrospun laminated fabric. 


  • Expedition Mummy shape with #5 YKK two-way zipper with locking sliders
  • Dual zipper draft tube system
  • Pertex® Shield EX water-resistant/breathable shell with DWR with a Pertex® Shield Air electrospun panel on the top middle for added breathability
  • Pertex 30 denier taffeta lining
  • Permanent collar with EX facing to prevent breath condensation from entering the bag
  • Side-block baffles maintain a 60:40 top to bottom insulation distribution
  • 3D contoured hood wraps a layer of down around your head
  • Generous draft tube prevents cold air from seeping past the zipper
  • Large side walls ensure even insulation all around
  • Overlapping dual-webbing zip guard guides the fabric away from the zipper
  • Tuck-stitch construction hides the baffle threads and prevents moisture from wicking through to the inside
  • Includes storage bag & stuff sack
