I've had my Mission Wallet for a couple months now.
Carry Space Pen in the small pocket, and a Vic Rambler and ARC AAA in the big pouch.
Biniz cards behind, small first aid kit & freznel lens inside zipped area.
Haven't replaced wallet yet, but the DOPP Front Pocket looks promising.
DOPP in my left front, and the Mission in right would work.
Haven't seen any fraying or leather changes.
So far, so good.
