Big Agnes Bald Mountain 18 Sleeping Bag (Synthetic) -

Bald Mountain sounds like a scary place to visit (a vision of the future!) but it won't be nearly as frightening if you spend your nights in the Bald Mountain 18-Degree Synthetic Sleeping Bag from the hirsute cats at Big Agnes. You'll be warm even if all your hair falls out, courtesy of a contoured drawcord hood and mummy shape that increases warmth while decreasing weight. And courtesy, of course, of the synthetic Pinneco Core insulation that's wrapped in a tough nylon shell.

Unlike down, Pinneco's warm even if it gets wet, but it's also breathable and uses a Core Screen layer that resists external moisture while actively drawing condensation from inside the bag, keeping you warm as a wolverine and dry as a sand worm all night. A no-draft collar and no-draft zipper lock out drafts (bet you didn't see that coming), while Insotect Tubic baffle construction uses vertically-baffled insulation to better conform to your body and provide superior loft and support. You can also mate together left- and right-zip bags if you feel the need for a doublewide.

The Big Agnes Bald Mountain 18 sleeping bag is a new bag that will keep you out on the mountain farther into the year. With its great insulating capabilities you'll be comfortable when the weather turns nasty towards the end of backpacking season.
Insotect Tubic is a revolutionary tubular insulation system engineered to provide the maximum cubic loft for supreme thermal efficiency and user comfort. Through its innovative design and construction, Insotect Tubic delivers performance benefits that make gear significantly loftier, warmer & more durable. Superior thermal efficiency - the significant air space created by the DualVault and Vertical Thermal Channel delivers the best thermal efficiency.
Pinneco Core is a new synthetic insulation designed to be more breathable, thermally efficient and sustainably engineered. Pinneco's Core Screen resists water from outside, while the Core Fusion technology seals the insulation like an air pump, actively drawing sweat from inside the bag.
