Hi Bob. I have a nimbus ozone with the same suspension as the nimbus meridian. Almost a custom fit as there are three belt sizes and 4 harness sizes (shoulder). Plus the shoulder straps can be either wide or narrow and the pack itself has four torso length adjustments.

As far as the compression straps going over the pockets, this is not an issue for anyone who has actually used the pack. The pockets are super stretchy and will hold a lot. Once the compression strap is cinched tight, nothing is falling out of those pockets. Its actually a great design and one that I prefer over my ULA Circuit.
