The bag arrived last week, and I couldn't be happier with it!
The wheels are standard, pretty good. The space inside is enough for my 160cm board (could go longer, off), all the equipment (jacket, pants, helmet, boots, gloves etc).
I believe I could put in one or even two more boards, along with maybe another pair of bindings. Maybe it would be too much, but I will try to pack at least part of my wife's gear anyway.
The overall quality is... wow! I love it! The zippers, the fabric... everything is top notch! I am glad I got it even before I knew the dimensions. There are three big pockets that protrude inside the bag, and another set of "regular" pockets on the outside for... I don't know, small tools or documents or something not that big. Maybe balaclava or slim gloves.
Also, the customer support is great, worth mentioning :)
Thank you!
