I have been looking for a comfortable front pocket system to carry a notebook (currently using Rhodia A7) and a pen, maybe some cards. The Lochby sidekick seems like the most viable cover I have found so far, but I've read a couple of times that it's uncomfortable to carry. Are there other similar covers that are more pocket friendly?

I find a lot of field notes covers, but these all seem way to big to keep in a pants pocket.
