1. Thanks to its top-of-the-line 800-fill down, light fabrics, half-length zipper, and trim cut, the Adrenaline 20 packs down to the size of a loaf of bread. Even more impressive, at less than two pounds, the Adrenaline is about a half-pound lighter than the average 20-degree down bag. Add the unique zipper placement—right down the middle—and you’ve got a remarkably compressible and comfy bag.
2. The side sleepers among us especially loved not squirming around on top of a cold zipper all night. And although a few noted that unzipping the bag can be a claustrophobic challenge, most found that the central zip made the Adrenaline one of the comfiest bags they’d ever slept in. Ditto the snug-fitting and easy-to-adjust hood. It’s so well insulated that no draft collar is necessary.
3. Burly waterproof-breathable Pertex Endurance fabric caps the hood and footbox of the Adrenaline—the spots most likely to contact wet tent walls or peek out from tarp ends. To save weight and allow moisture to escape, the rest of the bag is clad with more breathable, yet still water-repellent, 20-denier ripstop nylon. Tip: It’s also available in zero- and 40-degree models and women’s-specific versions.
