Sea to Summit Basecamp Synthetic Sleeping Bag 20F/7C


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.

  • High-quality Thermolite® insulation is loftier and more durable for lasting warmth
  • Full-length YKK® #5 main side zips and foot box zip provide unmatched ventilation and allow the top section to be removed and used as a comforter
  • Removable straps to secure a sleeping mat underneath the sleeping bag bag (note: the 30” wide Comfort Deluxe mat will not fit into these straps)
  • Shaped hood and zipper draft tubes keep cold out and warmth in
  • Form a snug sleeping bag for two by zipping to another Basecamp, Explore, Ascent, Trek, Traverse, Altitude, Journey or Venture sleeping bag
  • Includes 70D nylon compression bag.
