Shape

Mummy

It offers high thermal performance thanks to its narrow design, which reduces air gaps and heat loss. It is lighter than rectangular ones, due to the use of less material. Recommended for hiking, mountaineering, or extreme temperatures.
Size Single
Filling

Down

It offers warmth, high breathability, and minimal weight. Sleeping bags with down take up little space as they are highly compressible. However, if they get wet, they lose their properties and are more expensive compared to synthetic ones.
