Big Agnes Fly Creek UL 25 (-4°C) Sleeping Bag
Premium, packable, minimalist mummy sleeping bag
Redefine backcountry comfort with the Fly Creek UL 25, the ideal ultralight bag for all your minimalist adventures.
Premium materials, like ultralight NetPlus® fabric made from recycled fishing nets and high-quality 850-fill down, along with a sleek design featuring Big Agnes Signature Diamond Quilting, produce a lighter, more packable bag. From the ergonmic footbox to the insulated draft collar, every aspect of this sleeping bag is designed to maximize thermal efficiency, without the need for extra weight and bulk. The result is a technical sleeping bag that is a backpacker's dream, perfect for fastpacking, thru hiking, or any overnight trip in three season temperatures.
Features
