There are a few critical items necessary to an enjoyable outing with the LittleFlogger. Key among these is a good sleep system, with the criteria for good being: synthetic fill (for spilled liquid, either from internal or external sources), roomy and warm. The Big Agnes Little Red +15F hits them all out of the park.
The Little Red is a rectangular polyester-fill bag with a DWR nylon shell that will house up to a 4ft 5in LittleMonster. The clever 2lb 9oz design incorporates mummy-bag features to maintain warmth: a cinchable hood, draft yoke around the neck and a beefy full-length draft tube backing the zipper. Two more features make this an ideal bag for kids: an internal pillow sleeve fixes the head support in place, and an external pad sleeve accomodates any 20″x48″ pad, such as the Big Agnes 3/4 length Air Core. No rolling off the pad, and really this feature alone makes this an awesome bag.
There are holes in the head corners that allow the pad to be inflated/deflated without removing it. The extra room allows for the normal kid night-long biathlon of tossing and turning, and there are internal loops for sleeping bag liners. The best thing to do is to set it up before you go camping and let your kid become familiar with it at home. The LittleFlogger will be jumping in and out of it in no time; don’t force it, it’ll happen. Once they’ve made friends you can hit the road, and you’ll both be in dreamland instead of fighting with your gear. Highly recommended.
