I love this wallet from Topo Designs. Made of 420D packcloth, it's nearly indestructible, but its simple, clean lines make it pretty elegant, too. Black with yellow interior, the wallet has four pockets for cards and cash. Handmade in Colorado! 

FYI: The Topo Designs wallet is low profile and weighs in at only 17 grams. This wallet is 4 1/4 x 3 inches and expands up to about 3/4 of an inch with full pockets.
