Big AgnesFly Creek UL 25 - Sleeping bag

When every gram counts but comfort remains non-negotiable, the Fly Creek UL 25 from Big Agnes delivers the goods. Weighing in at just 722 g soaking wet (or nearly so), this ultralight sleeping bag features 850 fill DownTek™ insulation that stays warm even in damp conditions, all without a trace of PFCs — good news for the planet. Its signature diamond quilting keeps the down from taking a vacation, while the hood and draft collar fend off unwanted drafts.

In terms of ergonomics, it’s a custom fit: an enveloping mummy shape, a spacious foot box for toes that like room, and a minimalist central zip for personalized adjustment. All wrapped in 10D NetPlus® ripstop nylon made from recycled fishing nets. Lightweight, ethical, cozy: a true gem for starry nights.
