Sleep outdoors like you do at home: together. The Exped MegaSleep Duo double sleeping bag is a 4-in-1 sleep solution, offering multiple configurations and temperature ratings for warm or cool nights.


  • Flip the bag over based on weather conditions: Dark Blue side up will keep you warm down to 25°F; Light Blue side up keeps you warm down to 40°F
  • Separate the top and bottom layers of the bag to create 2 single sleeping bags: 1 Dark Blue bag rated to 25°F, 1 Light Blue bag rated to 40°F
  • Draft tube along full length of zipper stops heat loss and enhances warmth
  • Central snap at head end reduces drafts when sleeping in couple configuration
  • Use this sleeping bag with any sleeping pad; designed to fit perfectly on an Exped MegaMat Duo 10 (sold separately) for an at-home sleep experience while in the outdoors
  • Quick-drying microfiber insulation is engineered for maximum loft while remaining lightweight and highly compressible; you can even take this sleeping bag backpacking
  • High-grade lining fabric provides soft feel next to skin
  • All next-to-skin fabrics are treatment free, minimizing your contact with allergens or chemicals
