A wallet with a money clip does away with the bill compartment: bills are laid flat under a metal clip instead of being folded and stacked. This noticeably reduces thickness — the most common reason why someone switches from a classic wallet.
Card slots are still included, and some models also feature a coin pocket. All offer RFID protection. The leather is predominantly vegetable-tanned cowhide, which develops a patina and darkens with use.
Those who prefer to carry coins separately can combine it with a card holder. The entire selection can be found under men's wallets.
