Like taking your own bed into the backcountry, the Big Agnes Dream Island 35 double sleeping bag eliminates the need to zip 2 bags together—so there's nothing getting in the way of cuddling at camp.


  • Updated shell fabric and lining have a PFC-free, water-repellent finish
  • Insulated with FireLine™ Max Synthetic, a 50% postconsumer recycled, multi-denier polyester insulation; blend of hollow and solid fibers maximizes comfort, loft and warmth
  • Works with 1 double-wide pad or 2 single pads with a total size up to 78 in. x 60 in.; ideal pad size is 78 in. x 50 in. (pad not included)
  • Pad Cinch System with adjustable drawstring easily connects the bag to your pad; middle secure point adds stability
  • Integrated pad coupler secures 2 single pads side by side
  • Antisnag zippers provide a smooth, quick zip; double zippers allow entry from either side of bag
  • With a full zip-off option, you can use the top quilted layer of the sleeping bag like a comforter or zip it together to create a single bag when camping solo
  • Offset quilt lines eliminate cold spots
  • Use the hand-tuck pockets at the top of the bag to keep your hands warm
  • Seal out drafts by cinching the insulated tube along the upper hood opening
  • Easily uncinch the hood with one hand using the low-profile cordlock
  • Your pillow (not included) stays in place throughout the night inside the integrated Pillow Barn
  • Free-range footbox provides more wiggle room for your feet
  • No-draft collar, no-draft wedge and no-draft zipper keep cool air from sneaking in
  • Use the interior fabric loops to secure sleeping bag liners (not included); easily hang dry or store the bag with the exterior loops
