...because it holds the passport inside securely but not tightly flat, it has allowed my passport's pages to dry out back to their original condition!  Previously I was keeping my passport in a sealed trifold wallet which must have been too airtight, because after my passport had spent a few weeks close to my body in a hidden security belt during my last trip, the pages were kind of damp and sticky.

Don't know how well the RFID blocking works because I haven't had any means of testing it yet.  But generally I do like travelling with this wallet, it makes it easier to locate my passport in my multi-pocket travel vest due to its heavier weight.  Sold build quality, too.  I also like that it conceals my nationality from casual passersby since in some parts of the world, being an American is not something you really want to advertise.

I do wish it had more pockets, especially one for cash...but oh well, you can't have everything!
