Balancing roominess, warmth, weight, and compressibility, the Big Agnes Sandhoffer 20 Degree sleeping bag is a versatile option for 3-season backpacking or camping.
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 rip-stop shell with a water repellent treatment bolsters protection and provides lightweight durability.
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 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 Sandhoffer Degree is available in Regular (fits up to 5' 10") and Long (fits up to 6' 6") lengths. Once you match your bag with a rectangular sleeping pad of the appropriate dimensions (20" x 72" for the Regular or 20" x 78" for the Long), spending a night in the bag is warm and comfortable. Note that the pad is sold separately.
A number of performance features further equip the bag for thermal efficiency. A contoured, insulated hood keeps your head warm and a no-draft collar keeps cold air from creeping in the top of the bag and reaching the bag's interior. A full-length draft tube sewn behind the zipper further ensures that cold air remains outside of the bag. A no-draft wedge protects the connection between the bag and the pad, so that cold air doesn't sneak in between the two.
A nylon stuff sack and mesh storage sack are included with each Big Agnes Sandhoffer 20 Degree sleeping bag.
