Big Agnes Lost Lake SL 30 Degree Sleeping Bag

Delivering the all weather reliability normally associated with synthetic insulation and the lightweight, compressible performance of down, the Big Agnes Lost Lake SL 30 Degree sleeping bag is a high performance option for backpacking in summer or mild temperatures.The Lost Lake SL 30 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 Lost Lake SL 30 Degree 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 Lost Lake SL 30 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.Available in Regular fits to 5' 10 and Long 6' 6 lengths, each Big Agnes Lost Lake SL 30 Degree sleeping bag includes a nylon stuff sack and a mesh storage sack.
