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.

We offer different cuts, lengths and widths in our sleeping bags to accommodate most body shapes and sizes.

Sleeping bag length
EXPED sleeping bags are sized slightly longer to provide adequate space in the foot box:

Standard sleeping bags:
S = 67 in.
M = 71 in.
L = 77 in.
XL = 83 in.

MegaSleep bags (Single and Duo):
M = 78.7 in
L = 82.7 in

Sleeping bag shoulder width (excluding MegaSleep)
EXPED designs its sleeping bags with three different widths, depending on the activity/needs of the user:

Standard fit: 31 in. at shoulder
Wide fit: 35 in. at shoulder
Slim fit: 29 in. at shoulder

Contours the body with enough space in the lower section to allow bending of the knees and enough space in the upper section to move.

Cut for those who prefer the highest possible freedom of movement during sleep. It's also a great option for stomach sleepers.

This body-hugging width is designed to save as much weight as possible without sacrificing comfort.

Note:We highly recommend trying out the sleeping bag for width and length before purchasing in order to determine the proper sleeping bag size.
