Thrashers Welcome

The 725-fill Tumble Mountain features recycled fabric, zipper, drawcords, and cordlocks, making it the most sustainable bag here. It's also the most tricked out. Big Agnes shaves a few ounces by eliminating the unnecessary insulation under the half-length pad sleeve on the back. Slide any standard-width (20-inch) pad into the sleeve and you'll never roll off your pad again. And the vertical baffles? As with the Montbell bag, the chambers are longer, meaning less fabric to lug around and more efficient heat retention. To keep the down from shifting inside the long baffles, which creates cold spots, Big Agnes installed lightweight mesh membranes every ten centimeters. 20º; 3 lbs;
Compressibility: 4.1
Warmth-to-Weight: 4.3
