These high - tech, ultralight sleeping bags are made for adventures where every gram matters. You'll use every bit of space in your pack, and just like you rely on a harness, helmet, or beacon, you can count on this sleeping bag's performance. The Big Agnes Star Fire UL series, often called the 'Fly Creek of sleeping bags,' is equipped with top - notch 850 fill power DownTek™ water - repellent down. It has a superlight, high - tear strength shell that also safeguards the footbox. The body - mapped baffle design maximizes thermal efficiency, making it the lightest and most compressible bag for your far - off overnight trips. Features include ultralight down mummy bags with 850 fill power, DownTek™ down and a Pertex® shell for extreme compressibility. The traditional mummy shape offers light weight and high thermal value. The 3 - D anti - snag draft tube stops heat loss along the zipper. Vertically structured sidewalls with contoured baffles keep heat close to your body. The contoured hood baffles provide a comfortable fit for your head. There's an oversized interior anti - draft collar and an ergonomic foot - box for more warmth. A low - profile cordlock lets you open the hood with one hand. An insulated tube at the upper hood opening seals out drafts when tightened. The minimal zipper reduces weight and cold spots. The 102 cm YKK #5 anti - snag zipper zips smoothly. It also has a zipper garage, interior fabric loops for liners, and streamlined exterior loops for drying or storage. Storage and stuff sacks are included. Specifications: Bag Weight 652 g, Fill Weight Regular: 284 g, Compressed Bag Size: 13 x 14 cm, Stuff Sack Size: 19 x 38 cm.
Using your Big Agnes Star Fire UL sleeping bag is easy. First, take it out of the stuff sack and let it fluff up for a bit to regain its loft. Unzip the bag using the smooth YKK zipper and climb in. Adjust the hood using the cordlock for a snug fit, and the insulated tube at the top will keep out drafts. The anti - draft collar around your neck will also help keep you warm. When you're done using it, gently compress it and put it back into the stuff sack for storage. For long - term storage, use the storage sack to keep the down in good condition. As for maintenance, try to keep the bag dry. If it gets wet, hang it up using the exterior loops to dry. Avoid machine - washing it too often as it can damage the down and the shell. If you must clean it, follow the manufacturer's instructions carefully. Also, be careful not to snag the zipper on sharp objects to keep it working smoothly.
