When you reach your yurt or raised lean-to shelter, peel off your skins, set up camp, and enjoy a toasty evening wrapped in the Sierra Designs Cal 13 800-Fill DriDown 15 Degree Sleeping Bag. Insulated with hydrophobic DriDown, the Cal 13 retains its warmth and loft even if it gets a bit damp.

  • With an EN comfort rating of 25°F (an average woman's comfort level) and lower limit of 13°F (an average man's comfort level), this bag is best suited for teen mountain temps or winter nights in sheltered yurts
  • 800 fill-power goose DriDown insulation features a hydrophobic finish that enables the treated down to stay drier, loft better, and dry faster compared to untreated down so you're able to stay warmer, longer in any situation
  • Insotect Flow construction features vertical down-filled baffles that help facilitate heat distribution more readily from head to toe than traditional side horizontal channels
  • Vertical channels also efficiently mirror the contours of your body, lessen down shifting, and reduce overall construction materials
  • FlowGate technology holds insulation in place for reliable warmth and comfort
  • Mummy-shaped bag decreases weight and packed size, which helps lessen your load when you backpack
  • A 10D ripstop nylon shell offers lightweight performance while a DWR coating supplies protection against early-morning frost
  • Ultralight jacket hood, ergonomically shaped footbox, and zipper draft tube insulate your body and prevent the cold from seeping in
  • Thermally efficient 40-inch snag-free zipper offers easy in-and-out
  • Collar drawcord with captured cordlock lets you cinch the collar down around your face for a snug fit
