I don't have any of the new cases (where the 'name' is the dimensions), nor do I have a 10-22mm any longer (replaced with a 16-35 II after getting a FF body). But...the 10-22mm with hood fit well in a Lens Case 1W, which is 10x12.5. With the UWA zooms, the hood won't fit reversed unless the case is very oversized. Instead, I put the lens in mount-up (as with all my lenses), and then set the hood over the lens barrel at an angle. Works for the 16-35, which is longer than the 10-22mm - there was some headroom with the 10-22mm in the 1W. So, I think the 11x11 would work, if you don't have the good actually mounted.
