Anvil Horn 0 (650 DownTek) LONG LEFT

Big Agnes System bags with DownTek™ insulation offer a roomy, rectangle-shaped sleeping space with an integrated Flex Pad Sleeve on the bottom. With technical fabrics and construction, compressible insulation and tons of comfort features, these comfortable sleeping bags are designed to be lightweight enough for backpacking but cozy enough you'll want them in the campground too. The streamlined silhouette and Flow™ construction increase the thermal efficiency keeping you warm from head to toe. The Flex Pad Sleeve unites easily with your pad, and as you change positions over the course of the night, will keep you from rolling off your pad.

More about Anvil Horn 0 

Big Agnes System Bags easily attach to a sleeping pad allowing you to comfortably roll around inside without rolling off your pad. The top panel of the bag creates a unique draping effect that feels more like the comforter on your bed at home. The insulation on the bottom of the bag is unnecessary in this system, so you won’t find any there, since heat is reflected from the sleeping pad back into the bag, you’ll want to make sure to add a pad to your cart!
