The Basecamp Thermolite synthetic sleeping bag is for those who prefer a luxurious and versatile sleep system. Each side of the Basecamp has a full-length side zipper; a third zipper can be found in the foot box zipper. The result is unmatched ventilation and the ability to remove the entire top section to use as a quilt. WaveLoft construction allows the Thermolite insulation to expand out into air-trapping curves for maximum warmth, and the overall shape of the Basecamp allows you to sleep in any position you choose.
