Our review

Minimal sleeping bag for the light traveller
Skip to view product specifications

OMM is a specialist in ultralight kit and the Mummery is its lightest sleeping bag, weighing just 460g.


Using high quality 860 fill power down feathers ensures it’s warmer than you’d expect, while its minimal design does away with zips to trim pack size to a miniscule 20x16cm. 

OMM stands for Original Mountain Marathon and that’s the original aim of this bag: it’s a super-lightweight for multi-day hill-runners. But its low weight and pack size make it ideal for summer bike touring.


Its construction means you can adjust the down distribution, so on a cold night you can move the feathers to the top and let your sleeping mat do the ground insulation.
