Product details

A 40ºF, ultralight, down sleeping bag made for summer backpacking or world travel, the Western Mountaineering MityLite weighs just 1lb, 10oz and packs incredibly small into a 6” x 12” stuff sack. Its semi-rectangular shape unzips completely to turn into a blanket, or it can be zipped to a Summer Coupler (not included) to sleep two people.

Key Features:

  • Sewn-Through Baffles – Continuous chambers of lofty, responsibly-sourced down insulation and Western Mountaineering’s proprietary ExtremeLite™ fabric make for an ultracompact, lightweight, and comfortable one-size sleeping bag.
  • Semi-Rectangular – The hoodless design saves weight, while the roomy fit accommodates various sleeping positions.
  • Full-Length Zipper – This bag can be completely unzipped to lay flat, like a comforter, or attach to the Summer Coupler (sold separately) to become a two-person bag.

This lightweight bag is rated to 40 degrees, and can be unzipped to serve as a blanket as well! Its looser fit also gives you plenty of room to move around.
