Quick overview

Sea to Summits most versatile and spacious sleeping bag, the Basecamp™ provides unrestricted movement and integration with your mat so you can enjoy a little more stretch out comfort while escaping outdoors.

Three two-way zips provide ultimate ventilation and temperature control and allow the top and bottom layers to be separated, with the top becoming a standalone quilt for warmer conditions.

Our 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. The baffle construction also eliminates the frustration of getting tangled in loose lining as all lining fabrics are attached to the shell fabric.

Perfect for sleepers who like to stretch out full length or curl up into a ball, the Basecamp™ provides versatile comfort for gear drops, car camping and day trips from base camp.
