it depends on his needs but i like a cardholder, it just lets me have the shit i need on me and keeps the overall footprint small so it doesn't feel too bulky
as a man my personal wallet history is
- current is by APC and i got it from my mom as a gift from SSENSE
- last was from Paul Smith (narrow fold cardholder w/zip pocket) and my mom also got that one as a gift when i first moved to Paris, it was just mad bulky
- before that I got myself a normal big wallet on holiday at Galeries Lafayette that ripped, and before that same thing but from Barney's and i lost that one
otherwise brands that are good are Rose Anvil, Maximum Henry, Filson, and really any brand that just does leather products ig. good full or top grain leather wallets with thick stitching that aren't super cheap don't break easily. i'd look there or SSENSE and irl idk maybe selfridges or john lewis and see what you find
