My boyfriend lost 2 wallets in the course of a year, including a lot of cash, while riding his bike. The result: a very bummed man. Girlfriend to the rescue, finds the Pacsafe wallet on Amazon, orders it and gives it to boyfriend. The result: a very happy man :) This wallet has velcro to close every orifice, and a stylish, understated chain to keep it attached to one's pants. We'll see if my boyfriend turns into Houdini and is able to lose this wallet...I'll keep you posted!
