Also the water repellent nylon provides the highest sleeping comfort in spring, summer and winter: completely without freezing and sweating.


When it comes to quality, material and workmanship go hand in hand. The best material is of no use if the workmanship is not right. This contributes significantly to water resistance and durability. The workmanship also has an influence on comfort.

A 4-season sleeping bag often consists of two separate sleeping bags - a thinner one for summer and a thicker one for winter - that can be combined to adjust the temperature range.
