Mummy – a design with high thermal efficiency
Mummy – a design with high thermal efficiency

Tapered mummy bags are the most popular shape for sleeping bags. And that’s for a good reason. The form-fitting design narrows towards your feet, meaning that less air needs to be heated in your VAUDE sleeping bag, which is very heat-efficient. Less fabric also saves resources making your VAUDE sleeping bag lighter and more compressible. The hood shape and thermal collar (not included in all models) prevent cold air from penetrating – mummy sleeping bags are the perfect companion in cold and challenging weather.

• optimal thermal efficiency due to a form fitting shape
• lightweight and very compressible
• perfect for challenging tours in any weather
