Ozone Saucisse Lite Bag review

I bought Ozone Saucisse Lite Bag Concertina (small size) for my Ozone Ultralite 4 size 21 wing. The concertina is very lightweight. The wing fits pretty good (I have to fold the trailing edge a little to fit the wing). The concertina has straps with buckles instead of zipper, zipper is easier to use (I have another different Ozone concertina with zipper), but this is the way to reduce the weight and buckles work OK.
