Tipping the scales at just over a pound, the Phantom™ 45 is the lightest bag in our line. A great summer bag for lower elevations and warmer climates, the Phantom 45 has a snug mummy fit built from Superlight 15 denier fabric. Insulated with 800-fill down.

Lightweight shell material, and premium 800-fill goose down allow us to craft a warm-but-featherweight sleeping bag-the Wicked Light. We realize, however, that skimping on details will only result in a poor night's rest, so we dial the Wicked Light out with removable Pad Locks, continuous baffle construction, and Snag Free Zipper Tracks. According to our research, cramped, overheated feet result in disturbed sleep, and Foot Box Venting allows you to regulate temps in the bottom of your bag. At just over a pound, the Wicked Light offers an unbeatable warmth-to-weight ratio…and a great night's rest.

A 45-degree bag like the Arrow Rock needs to adapt-summer heat waves in Monument Valley or Fourth-of-July snow at Conundrum Hot Springs, you've got to be comfortable. The Arrow Rock 45 gets it done with Flex construction for comfort and thermal efficiency, and continuous baffles so you can shuffle down to the top in cold weather or to the sides in the heat. If there's a more comfortable, versatile bag out there, please let us know!
