Sell a well-used, large-size Acro Base. Bought it in early 2015 and made a some flights with it. I only used the base rescue once. Was then folded by a parachutist. The straps are great! The loop in the 3 ring system is also perfect. Unfortunately the fabric on the side is torn and I sewed it on again by hand (see pictures). The new price was 3000 euros in early 2015.
