Versatility has met its match with the Yukon 10 Sleeping Bag. A 5-in-1 design allows you to use it as a cold weather sleeping bag for four season camping, as 3 separate bags to reach your ideal temperature, or as a double-wide bag for room to share or sprawl out in. A canvas shell, synthetic insulation, and a cotton flannel lining will keep you warm and comfortable, no matter how you choose to use it.
