The Finn Wallet by WaterField Designs is a tough, well-designed wallet that’s plenty spacious enough inside to carry your pocket odds and ends — cards, cash, coins, and even your smartphone, if the size is right. Here are just a few of their size options:

• Size 28: Holds an iPhone 6s, about 15 credit cards, and some bills.
• Size 29: Holds an iPhone 6s Plus, about 15 credit cards, and some bills.
• Size 42: Can hold a passport, foreign exchange, an iPhone 5s/5c/5 or other smartphone. Comes with a zippered coin pocket.

The Finn is made from full-grain cowhide leather that’s naturally tanned to feel soft and supple like deerskin. (It smells awesome too.) Around the edge is a YKK zipper that “locks” in place until the pull tab is used, which means the wallet won’t creep open on its own and spill its contents into your pocket or bag.

The interior of the wallet is lined with ballistic nylon and sports a pocket on each side. Those inner pockets are ideal for holding cards and coins, while the central space is where your cash, receipts, and even smartphone can live.

The Finn comes in six leather colors — black, camel, grey, red, forest green, and cowboy brown — or you can opt for black “flash” nylon or tan waxed canvas. Depending on the size you choose, the wallet will run you $39–$49 at sfbags.com.
