As with previous Kazoos, this 15-degree bag is still stuffed primarily with 600-fill down and bedecked with smart features—glow-in-the-dark zipper pulls, easy-to-adjust hood, etc. Even more impressive, this Kazoo’s shell and insulation are made with 100 percent recycled materials. Plus, it’s a hybrid. There are compression-resistant, synthetic insulation pads at key pressure points, including your shoulders, back, bum, and feet, where your body usually squashes the down against your sleeping pad. Translation: fewer cold spots and more tropical dreams. 15°, 3 lbs;
