Big Agnes Lost Dog Sleeping Bag: 30F Synthetic

$169.95 - $179.95

Lost Dog Sleeping Bag

The Lost Dog 30-degree sleeping bag from Big Agnes stands up to any shoulder season adventure you've got planned. At just over 2 pounds, this sleeping bag is light enough for high-mileage treks without sacrificing comfort—like a no draft collar, single-handed cinch hood, and free-range footbox. Create additional comfort by zipping the bag to another from the Big Agnes line to snuggle up to your partner for an even warmer experience. And by sliding your sleeping pad into the pad retainer, you can ensure full-coverage even if you both toss and turn throughout the night.
