The last thing you want is little Billy and Bonnie trying to squeeze inside your sleeping bags because theirs are too cold. Send them to bed with a pair of Big Agnes Wolverine 15-Degree Synthetic Kids' Sleeping Bags and this won't be a problem, because the Wolverine's synthetic insulation, adjustable hood, and integrated pad sleeve are designed to keep the kiddos nice and toasty throughout the night, even when the temps dip below freezing. A zipper-covering draft tube and draft-blocking collar work to seal out cold air from creeping in, too, so the half-pints stay warm and, more importantly, asleep until the sun starts to shine.
