The Buffalo 4S Inner Sleeping Bag Liner can be used on its own for bothy trips or camping and backpacking in warmer weather.
Combined with the 4S Outer it can be used all year round in sheltered places. With the further addition of the Buffalo Thermaliner, either between the Outer and Inner or inside the Inner as protection against dirt, you have a full 4+ season system, for protection and comfort all year round.
The 4S Inner features a robust 3/4 length zip, complete with added temperature protection from a zippered hood closure and internal tape loops for attaching either the 4S Outer or the Thermaliner.
