Its always nice to see a designer work with sustainable materials used for many many years and really think about every element that goes into a product. John Cho Moore a RISD grad who is now based in San Francisco builds beautifully constructed bags. John also makes intelligently designed wallets check his Facbook page for more info.
I like to see people design and build products built to last many years made from time tested materials. It is products like these that are the ultimate in sustainablity as they rarely need to be replaced.
