The Gradient Aspen is a Czech single-place, paraglider designed and produced by Gradient sro of Prague. Introduced in 2003, it remained in production in 2016 as the Aspen 5.[1]

Design and development

The Aspen was designed as an intermediate sport glider.[1]

The design has progressed through five generations of models, the Aspen, Aspen 2, 3, 4 and 5, each improving on the last. The models are each named for their approximate wing area in square metres.[1]
