Built especially for backpacking couples, the Big Agnes Saddle Mountain SL 15 Degree Double Wide sleeping bag offers lightweight packability with room for two! Insulated with water-resistant 700-fill DownTek insulation, the Saddle Mountain SL 15 Degree Double Wide bag delivers performance regardless of conditions.
The Saddle Mountain SL 15 Degree Double Wide 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 Saddle Mountain SL 15 Degree Double Wide 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.
In a traditional sleeping system, the bag lies on top of a sleeping pad. In this configuration, many people find themselves rolling off the pad at night. Plus, the insulation on the bottom of the bag is compressed by the sleeper's weight. Once compressed, the fill loses most of its insulating properties. The Big Agnes Sleep System is different, joining the bag and pad together. The pad slides into a sleeve on the bottom side of the bag, supplying insulation to the otherwise uninsulated bottom of the bag while the top and sides of the bag are insulated like a traditional sleeping bag. This design provides a secure foundation so you can roll, twist and turn freely during the night without ever rolling off your pad. It also prevents the bag from twisting and engulfing you in an uncomfortable mess. Big Agnes uses this system throughout their entire line of sleeping bags.
The Saddle Mountain SL 15 Degree bag requires two 20” wide pads. Once you match your bag with sleeping pads of the appropriate dimensions, spending a night in the Saddle Mountain SL 15 Degree bag is both warm and comfortable.
A doublewide insulated ergonomic hood, draft tubes located along the length of the dual zippers, a center no-draft flap and separate insulated neck yokes lock in heat and keep out cold air to enhance the warmth and comfort provided by the Saddle Mountain SL 15 Degree bag. Built-in pillow pockets hold Big Agnes Air Core Pillows (sold separately), clothes or other pillows, providing a comfortable resting place for heads and necks.
Each Big Agnes Saddle Mountain SL 15 Degree sleeping bag includes a mesh storage sack and a nylon stuff sack.
