Duplicate your at-home sleep experience in the outdoors — Together! MegaSleep Duo is a supremely versatile 4-in-1 sleep solution, offering multiple configurations and temperature ratings. It covers couples and solo sleeping with warm and cool night options. Simply flip the bag over to change the amount of insulation on the top side – dark blue side up for cool nights (down to 25°F), light blue side up for warm nights (down to 40°F). Additionally, each side can be converted into a solo bag or blanket, creating one for cool nights and one for warm nights. Designed to fit EXPED MegaMat and MegaMat Duo, MegaSleep is the lightest and most compact duo sleeping bag in its class. It was designed specifically for use as an overlanding and car camping bag. However, because it weighs just 4 lbs. and compresses amazingly well, it can also be used for human-powered adventures such as backpacking, kayaking, canoeing, etc. Shape Rectangular/blanket Temperature Range Comfort temp: 40 °F Limit temp: 25 °F Extreme temp: 5 °F Weight M: 70.2 oz L: 80.8 oz Dimensions M: 63 x 78.7 in L: 63 x 82.7 in Fits up to body size M: 75 in L: 79 in Packed Volume M: 14 L L: 14 L Includes Sleeping bag, mesh storage duffle
