Bag recommendation for OM-D

I've been using the Tamrac Expedition 4x for several years. Well built and it's waterproof, which I know for a fact works very well A large wave on a small boat swamped everything and everybody on the boat - interior of the bag was dry as a bone. After that experience I became a fan of Tamrac.

Now that I'm with m43, I could downsize to the Expedition 3.
