Buffalo first started by making sleeping bags in 1979, and in fact patented the concept of Pertex / Pile Bags. They form an integral part of the DP System and by the combination of bags to the requirement of the user, ensure not only a comfortable night's sleep, but a comfortable nights sleep throughout the bags life. As twice as much insulation is required in winter compared to summer, it seems logical to have a sleeping bag comprising of two layers, which can be used all year round.
The 4 Season system comprises a 2/3 season Outer (the 4S Outer) to which can be added either a 1/2 season Thermaliner to make it a 3 season bag, or an additional 4S Inner Bag to make it into a full 4 season winter bag. From this combination the bags can be split to two separate bags for use between April and September, the Thermaliner being used as an outer shell for the 4S Inner making an independent 2/3 season bag.
All the bags are suitable for the most arduous usage, being used continuously over periods of years. No need to dry clean, they can be easily washed in industrial launderette machines, or even weighted down by rocks on a riverbed. The real advantage of these bags is that even if they are wet they still retain their insulating qualities and will keep the user warm. There are verified accounts of unusable wet down bags being inserted between a 4S Outer and a 4S Inner when the user went to sleep. After a comfortable night's sleep the user found that the down bag belonging to his companion had dried out enough to be used the next night.
