Description || Basecamp Synthetic Sleeping Bag


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.

Frequently Asked questions

Warm enough for cool weather camping or travel?

Yes. The quality insulation and technical construction keep you warm even on chilly nights. The Basecamp 10°F – paired with a greater than 3.5 R-Value sleeping mat, like the Comfort Plus Insulated, would be warm enough for Spring through late Fall.

Fitted with a sleeve to slide in a sleeping mat?

No. Something better than a sleeve: 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.

Suitable for summer temperatures?

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