Good suitcase, it can fit two helmets but mine, which are size small, one jet and one foldable, barely fit. Larger sizes definitely won't fit. As soon as I clicked it onto the rack, it makes noise. I mean, the lid probably hits and it drives me crazy. Also, regarding waterproofness, it might be fine in the rain, but when I washed the bike in a washing machine, as I was washing it with the pressure washer, water got inside. The positives are that it has internal hinges and not straps, and it stays stable when opened. Also, when you open it, you take out the key, and after you close it, it stays locked, which is very positive for me. That's about it.

War dog. On sh300 it withstood half of Italy with 23 kilos inside and 4 kilos on the lid held with a net. Its square shape is also a positive feature as it makes sorting things easier. For this price, I consider it a one-way street, although it somewhat limits the gray color it has on the lid.
