The Nitro Zero Degree is an incredibly warm bag for its weight--less than three pounds--and packs down to the size of a loaf of bread. That's possible thanks to the 800 fill power high quality down used in its manufacture.

This is an expensive, state of the art bag, Regular Length, that has never been out of its storage sack. The bag usually sells for $500, I saw it on Sierra Trading Post for $395, I'm selling this brand new bag for almost half that. This is a great deal for serious go light backpackers, climbers and wilderness travelers who want a top of the line, ultra light zero degree sleeping bag.

Here's what Backcounry.com says about this bag:
"It's tough to find a bag as warm as the Sierra Designs Nitro 0-Degree Down Sleeping Bag in the sub-three-pound range. The Nitro bag packs into an impressively small sack, and the Nitro's Flex construction provides comfort while allowing Sierra Designs to shave ounces. "
