The fibers of the polyester yarn have channels that collect warm air, so it retains the heat given off by the body and insulates against the cold even in humid environments. A huge advantage of the Hollowfiber-1 is the short drying time, which is of great importance especially in off-road conditions. The sleeping bag is designed for use from spring to autumn. The Campus PIONEER 200 provides sleeping comfort at temperatures between 9° and 13°. A comfort temperature is one in which a person maintains thermal balance and does not feel cold. This value refers to a woman after an average effort. This is a key parameter that women and people who freeze easily should follow when choosing a sleeping bag. The extreme temperature for this model of sleeping bag is between 3° and 8°. Sleeping in temperatures below this value can lead to hypothermia and loss of rest comfort, so it is not recommended to stay in the sleeping bag for more than 6 to 8 hours in such conditions. Layered construction of the sleeping bag: Outer layer: polyester 100% breathable fabric (gives off water vapor), which does not let cold moisture pass through Middle layer: HOLLOWFIBER-1 200g/m2 - siliconized polyester fiber with hypoallergenic properties, which wicks sweat away. The fabric has good insulating properties due to a network of hollow micro channels that collect warm air inner layer: polycotton (yarn of polyester and cotton fibers) soft fabric extremely pleasant in contact with the skin, which retains the heat given off by the body and allows water vapor to pass through
