DESCRIPTION

The Big Agnes Cross Mountain sleeping bag is incredibly versatile and keeps you warm down to 40F. The Big Agnes Cross Mountain is super lightweight and packs down very small. It has a dual-purpose design: Use it as a warm weather summer bag OR as an overbag that adds approximately 25 degrees to any traditional 3-season bag for winter camping. Simply insert the 3-season bag inside the Cross Mountain. Its Durable Water Repellent (DWR) outer shell fabric will shed moisture and keep the inside bag dry, ideal for winter conditions. Big Agnes makes sleeping bags without insulation on the bottom of the bag because down and synthetic insulation compressed by your weight loses virtually all of its insulating value. Instead, Big Agnes puts a sleeve in the bag floor into which you slide your sleeping pad, and the top 2/3 of the bag is insulated like a traditional sleeping bag. This system offers several major advantages: 1. An air or foam mattress provides more warmth than compressed insulation. 2. Youre guaranteed never to roll off your sleeping pad in the middle of the night. 3. It reduces overall weight of the bag, and therefore your pack. 4. The bag and pad can be stuffed together for compact packing. Compatible with any 20 wide rectangular sleep pad. FOR BIG AGNES PADS, SEE BAG0007, BAG0008, & BAG0011.
