The Basecamp Thermolite synthetic sleeping bag is for those who prefer a luxurious and versatile sleep system. An extremely spacious bag with multiple configurations for ventilation and comfort.

The full-length side zippers and foot box zipper can be opened for ventilation or to remove the entire upper section for use as a comforter in warm weather. The main side zippers can be zipped to Basecamp, Explore, Ascent, Trek, Traverse, Altitude, Journey or Venture sleeping bags.

The quality insulation and technical construction keep you warm even on chilly nights. WaveLoft construction allows the Thermolite insulation to expand out into air-trapping curves for maximum warmth. The Basecamp paired with a greater than 3.5 R-Value sleeping mat would be warm enough for late Spring through early Autumn.

The lower part of the Basecamp is fully insulated to avoid cold spots. Straps on the underside attach to a sleeping pad of your choice to form a roomy, cozy sleep system.

The overall shape of the Basecamp allows you to sleep in any position you choose.

Great for car camping.
