I am incredibly impressed with this Carhartt wallet. Right out of the box, you can tell the full-grain brownish saddle leather is top notch quality. It has a great weight to it, feels incredibly durable, and has that authentic, premium leather smell. The stitching around the edges is heavy-duty and tight, so I don't see this fraying anytime soon.It holds all my cards and cash perfectly without getting uncomfortably bulky in my pocket, and the built-in RFID blocking gives me great peace of mind. It’s starting to break in beautifully and develop a nice patina already. If you want a rugged, functional wallet made from actual good materials that will last for years, this is absolutely worth it. Highly recommend!
