The most versatile and spacious sleeping bag from Sea To Summit, the Basecamp allows unrestricted movement and integration with your sleeping mat so you can enjoy a little more freedom and comfort while camping in the outdoors. Fitted with a total of three two-way zips the Basecamp provides the ultimate in ventilation and temperature control and allows the top and bottom layers to be separated, with the top becoming a standalone quilt for when the conditions call for it. The unique WaveLoft construction uses thick layers of THERMOLITE insulation looped together to gain extra loft and trap pockets of warm air, providing increased warmth in colder conditions. Sick of getting tangled up in the middle of the night? the baffle construction eliminates this frustration as all lining fabrics are attached to the shell fabric. The Basecamp is the perfect sleeping bag for those who like the freedom to stretch out full length or curl up into a ball.
