The new Pamir range addresses the demand for ultra lightweight performance sleeping bags through the use of a quality duck down mix combined with the superior Toray Taffeta nylon shell and Taffeta nylon lining to produce two models with a starting weight of just 590g. Design features also reduce weight: the Pamir 250 features sewn-through construction while the Pamir 500 has a sewn-through base with a box wall upper. Both sleeping bags feature a half-length centre zip for convenience and further weight reduction.
