A mummy style bag with built-in expandability, the unique Big Agnes Torchlight 20 Degree sleeping bag offers versatility for 3-season backpacking or camping. By employing weather-resistant treated down insulation, it also ensures performance even in wet or damp conditions.
The bag is insulated with 600-fill DownTek insulation. Down insulation has long been renowned for its compressible properties and efficiency in delivering an excellent warmth-to-weight ratio. The shortcoming of down has been its susceptibility to the effects of moisture, losing much of its performance qualities when wet or damp. DownTek insulation utilizes nano technology and a proprietary application process to provide water-repellency and both anti-microbial and anti-bacterial protection. A nylon ripstop shell with a DWR finish further protects against the elements while a polyester taffeta lining enhances comfort.
Baffled construction helps to eliminate cold spots. Zippered side panels that run from the shoulders to the foot of the bag allow you expand the overall girth of the bag by 10” (5” per side) so you can choose between maximum thermal efficiency or extra room to sprawl. Other features include an insulated and contoured hood, an ergonomic footbox, a mesh interior stash pocket, an interior draft collar, and a draft tube that runs the length of the 65" zipper to lock in heat and keep out cold air. Integrated internal loops enable you to use the bag with a liner (sold separately) and external loops let you easily hang the bag to dry or in storage.
Available in Regular (fits to 6' 0") and Long (6' 6") lengths, each Big Agnes Torchlight 20 Degree sleeping bag includes a storage sack and a stuff sack.
