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

Is this sleeping bag warm enough for cool-weather camping or travel?

Yes, the quality insulation and technical construction make this sleeping bag perfect for chilly nights. Pair the Basecamp 10°F bag with a sleeping pad that has an R-Value of 3.5 or higher, like Comfort Plus Insulated, for warmth and protection from spring to late fall.

Does this sleeping bag have a sleeve to fit a sleeping pad?

This sleeping bag does not have a designated sleeve for your sleeping pad. Instead, the lower section of this sleeping bag is fully insulated to avoid cold spots and features elastic straps to secure your sleeping pad (up to 25" width).

Is this sleeping bag suitable for warm weather and summer temperatures?

Yes, with full-length side zippers and foot box zipper for ventilation, this sleeping bag is perfect for warm-weather camping. For hotter nights, simply remove the upper section completely for a lightweight comforter.

And, for an added bonus, the main side zippers can be joined with Basecamp, Explore, Ascent, Trek, Traverse, Altitude, Journey, or Venture sleeping bags.
