With its extra wide fit and a thick, warm construction, the Sea to Summit Basecamp™ 20 Sleeping Bag is a great option for car campers who like to lay on their sides, thrash wildly in their sleep, or just like a bit of extra room and comfort. Two full length side zips helps ventilate on warmer nights, topped off with a foot box zip and elastic sleeping pad straps to really get comfy.
30D Nylon Shell Treated with DWR
WaveLoft™ Construction – WaveLoft™ 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-1 – HL-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 Volume, Regular – 8.8L
Compressed Volume, Long – 10.9L
Shape – A generous shape to allow you to sleep in any position without compressing the down insulation and creating cold spots.
