The Patizon mummy sleeping bag D 290 L Fired Brick - Sky Grey 200 -18°C - Red is an ultralight sleeping bag with an excellent balance between thermal comfort, weight and compactness, all while maintaining all technical details. The D 290 features a straight front zip, which not only improves the sleeping bag's thermal performance, but also makes the zip easier to operate and reduces pack volume. The sleeping bag is just the right size and weight, keeping it out of your way but still providing the warmth you need for any summer adventure. More experienced and cold-resistant users can use it comfortably from May to September. And in winter, it is a great choice for mountain huts and winter rooms.

This temperature represents the lower limit at which the user is in thermal equilibrium, neither feeling cold yet warm (determined by a healthy woman under normal conditions of use.

Temperature limit -2°C

The limit temperature represents the lower limit of thermal comfort at which the user's body is in thermal equilibrium (the person is neither cold nor too hot). Determined for a healthy man and standard user conditions.
