ltra cool and ultra light: Like our tried and tested Swinger, the Mountain Swinger is sewn to an ergonomic and ultra comfortable seat form. The material for utmost demands is soft and cellular parachute silk (210 D nylon). The coated aluminium rods are collapsible, and so an ultra-small packing dimension is achieved as a result. Despite a slight weight of only 800 grams, the foot perch should not be left out!
