Product Info

The Sea to Summit Basecamp™ 20 Double Sleeping Bag is the double-wide version of the already generously roomy Basecamp bag. This means that it is great for couples, or true kings and queens who sleep solo and know what they're about. The Basecamp Double features full zips on both sides, so you don't have to wake up your sleeping partner if you need to get up in the middle of the night, and also allows the top section to zip completely off and be used as a comforter. This giant sleeping bag is the ultimate in car camping luxury.

Product Details


30D Nylon Shell Treated with DWR


WaveLoft™ ConstructionWaveLoft™ is a unique construction technology designed to maximize loft and minimalize insulation weight. Instead of conventional flat layers of insulation (sewn flat on top of each other) or shingle layers (sewn in diagonally overlapping layers), WaveLoft™ creates curved layers which expand out from the shell to trap the greatest amount of air possible at a lower overall weight than existing synthetic insulation constructions.

Thermolite HL-1HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibers, which provides excellent lightweight warmth with superior durability. The Thermolite insulation lofts up inside the Air Sprung Cells™ of our sleeping mats to prevent convective heat loss from your warm body to the cold ground.


Compressed Volume16.4L
