Mummy shaped sleeping bags are the most common style of sleeping bag you'll come across, and if you want to ensure your child is nice and warm during the night, choosing a mummy shaped sleeping bag for your child is a must. Mummy shaped sleeping bags have a tapered shape, which minimises on empty space inside. When sleeping bags have empty space inside, this creates cold spots within the sleeping bag and doesn't provide as good a level of insulation.
Mummy shaped sleeping bags also hug your body & feature hoods for a more cosy feel & added insulation. Another benefit to mummy shaped sleeping bags compared to rectangle shaped bags is that they use less material due to their tapered shape, this makes them more compact when they are packed into their storage stuff sack, so kids can carry them easily!
So far, zero complaints!
Comes in a dry sack like bag which offers little to no compression but switch it out for a proper one and it bunches down exactly as stated. Fits perfectly in my winter trekking/climbing bag.
Super warm, tested on the hills in a mild-ish Scottish evening but in the path of a freezing gale. Kept warm (occasionally too warm!) in the bivvy the whole night in just base thermals. The baffle ties and hood worked as you'd hope!
Will be my go-to sack in colder climbs.
