If you actually want this wallet, you'll care about this part first: I'm at 3.0oz fully loaded with as much cash as you can lay down at the cheapest no-limit poker table in the Bellagio, 6 cards, 2 office/garage entry badges, and a dog poop bag. Too much s***, but nowhere near Costanza levels. It's compact and refined, and will keep you that way.
I used to carry a sleeve-type wallet after I decided that my "pocket dieting" (periodically reducing what you carry) should become "pocket anorexia" (systematically carrying less). It was great, but a little... lacking. Like wearing "elegant man sandals" to dinner on a tropical vacation. It'll do, but you find yourself wondering if you deserve to be taken as seriously as the guy who bothered to bring real shoes.
This wallet is a step up from the sleeve... You won't preclude better service when you pull it out at your favorite hotel, casino, bar, or Michelin-starred restaurant.
The craftsmanship is superior. Stitching at the ends is loose, but the leather is only getting better.
Bottom line: It'll last you 5x longer than you'll need it to, and will never make you feel inadequate when you whip it out. That's the measure of what belongs in a man's pocket.
