The Original Flea Bag
Refinery 29 has a current reserve for the Original Flea Bag. You can choose from paying $50 for $105 or $150 for a $305 value. I love the Kelly green logo on the white canvas and all the leather accents. There are several variations to choose from.
Wood and Faulk
I found Wood and Faulk through Design Sponge. I love the leatherwork in their handcrafted products. They have a bag that is similar to the Heritage Leather Company mason bag I posted.
I also love the look of their natural leather belts.
