The Advance Epsilon is a family of Swiss single-place paragliders, designed and produced by Advance Thun of Thun.[1]

Design and development[edit]

The Epsilon was designed as a basic-intermediate glider intended for thermalling flight.[1][2]

The design has progressed through eight generations of models, the Epsilon, Epsilon 2, 3, 4, 5, 6, 7 and 8, each improving on the last. The models are each named for their rough wing area in square metres.[1][2]
