I have just started using an Ecosystem medium size notebook that is 5.25″ x 8.25″
I was looking around for a cover that would fit it, I ran across the Maxpedition Field Book Cover which looks nice, but I know its made for the Rite in Rain notepads which are a bit smaller.

Anyone have one of these? What notebook are you using in it?
Could you please take some measurements of the inside, where the notebook cover would slide into it?

Thanks
