Just as a heads up, it looks like Sand has updated the design of their OP-1 case (they told me that the change is: "
These OP-1 Cases are now bound on the outer edge instead of inside edge. This allows for the OP-1 to more easily slip inside the case without getting hung up on the inner binding.")http://www.sandisacult.com/product/op-1-cargo-softcase-orange
I haven't received it, so can't vouch for it, but wanted to share in case anyone else like me is looking for case options.
