This roomy, rectangular 3-season Exped MegaSleep 25/40 sleeping bag transitions from car campground to trail, thanks to lightweight microfiber insulation and separate cool- and warm-weather sides.


  • Multifunctional: Just flip the bag over based on weather conditions; dark blue side up will keep you warm down to 25°F and light blue side up keeps you warm down to 40°F
  • Rectangular shape is long and wide for maximum comfort
  • Quick-drying microfiber insulation is engineered for maximum loft while remaining lightweight and highly compressible; you can even take this sleeping bag backpacking
  • 40-denier ripstop nylon shell is durable and quick-drying; DWR-free, 40-denier nylon lining is soft, supple and comfortable next to skin
  • All next-to-skin fabrics are treatment-free, minimizing your contact with allergens or chemicals
  • You can use this sleeping bag with any sleeping pad, but it's designed to fit perfectly on an Exped MegaMat (not included) for an at-home sleep experience in the outdoors
  • Full-length zipper with dual sliders extends around foot section and allows the rectangular bag to be opened into a blanket
  • Glow-in-the-dark zipper pulls can be quickly located in the dark; zipper pulls are locking to allow precise positioning for ventilation
  • Draft tube along full length of zipper stops heat loss and enhances warmth
  • Head-end drawcord, with dual adjustment toggles, snugs up around shoulders to limit heat loss and increase warmth on cooler nights
  • Includes a convenient, adventure-ready storage duffel
  • OEKO-TEX® Standard 100 certified means this product has been tested for harmful substances and shown to meet rigorous human ecology criteria
