Why we like it Leave the tent at home: This bag-bivy combo can handle most any forecast in its temp range.
Waterproofing The waterproof/breathable eVent shell, taped seams, and waterproof zipper proved impervious to moisture, even in the worst conditions. One tester bivied in an open skiff off the Alaskan coast when he couldn’t find safe passage through a rocky shoreline before nightfall. “I was pummeled by rain all night, and I slept with just a shell over my face. I couldn’t believe that I was totally dry come sunrise.”
Warmth Crux uses alternating, overlapping, V-shaped baffles in the torso (they enhance loft, thus warmth) and lighter weight, slant-wall baffles over the legs. The hybrid construction lets Crux add an eVent shell without a major weight penalty compared to less weatherproof bags. Combined with ultrapremium 925-fill goose down, it kept testers warm right down to the temp rating.
Fave feature It comes in 64- and 67-inch girths (most bags measure closer to 60 at the shoulders). “I’m a stocky guy with a 46-inch chest,” says one tester. “I often get claustrophobic in standard mummies, but this bag draped comfortably across my shoulders.”
bummer Performance like this ain’t cheap.
