The Big Agnes Lithia Spring SL 15 is a traditional down mummy sleeping bag for women featuring water-repellent DownTek.
Delivering the all-weather reliability normally associated with synthetic insulation and the lightweight, compressible performance of down, the Big Agnes Lithia Springs SL 15 Degree sleeping bag delivers 3-season performance for female backpackers.
Big Agnes employs ergonomically tailors its women’s bags to properly accommodate female backpackers and campers. These bags are cut wider at the hips and have a shorter overall bag length to ensure thermal efficiency. Additional insulation in the foot box and the core area of the sleeping bag account for those areas women most often find difficult to keep warm.
The Lithia Springs SL Women’s 15 Degree bag is insulated with 700 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 microfiber rip-stop shell also features a water repellent treatment and provides lightweight durability.
Insotect Flow technology is used in the Lithia Springs SL Women’s 15 Degree bag to help eliminate cold spots, regulate the movement of down inside the baffles and offer better body heat distribution. Strategically placed Flow Gate construction eliminates lateral and vertical down shifting by using vertical chambers with "gates" to control the position and density of the down insulation.
A number of other design features bolster the warmth and comfort of the fully-insulated, mummy-shaped Lithia Springs SL Women’s 15 Degree bag. An insulated ergonomic hood, a draft tube located along the length of the zipper, and an insulated neck yoke lock in heat and keep out cold air. Integrated connection loops enable you to use the bag with a liner (sold separately).
