Robens says about the Green Cone PRS
The versatile polyester Green Cone PRS tipi has great headroom, a large porch and inner that sleeps four. It features an offset centre pole for easy access. This lifts the outer from the ground to create a gap to aid air flow. To save weight, remove the inner and adjust the telescopic centre pole so the outer sits close to the ground - the perfect bivvy tent. Small corner poles are sewn into the dark inner to create a wall that adds extra useable space.
