The Big Agnes Elk Park -20 Degree Sleeping Bag is an extra-roomy, extra-comfortable bag designed to provide maximum warmth for cold climates and winter camping. The Elk Park -20 Degree Long's generous cut fits large campers up to 6' 6" and a chest size up to 56" or anyone who just wants some extra room to roll around.
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 bottom of the bag while the top 2/3 of the bag is 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 Elk Park -20 Degree is designed to be used with Big Agnes 25" wide rectangular sleeping pads. However, other branded pads with the correct dimensions (25" x 78") will also work. Once you've matched your bag with the appropriate sleeping pad, spending a night in the Elk Park -20 Degree is like sleeping in a bed with the mattress under you for comfort and the covers for insulation.
The Elk Park -20 Degree weighs less and has more leg room than other comparable camping sleeping bags, which makes it more comfortable. It also packs down smaller and has more room to stretch out than other comparable bags.
Insulated with high-performance, quick-drying Thermolite Quallofil synthetic fill, the Elk Park -20 Degree is ideal for wet conditions or humid climates that would hamper the performance of a down-filled 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 to enhance the warmth and comfort provided by the Elk Park -20 Degree. A built-in pillow pocket holds the Big Agnes Air Core Pillow (sold separately) or other pillows or clothes in place, providing a comfortable resting place for your head and neck.
Available in your choice of left or right side zipper, each Elk Park -20 Degree sleeping bag includes a nylon stuff sack.
