A few years ago my friend Katherine purchased a messenger bag made by Teamwork from salvaged sails and tractor tires. It's a darn good looking bag. Yellow and green and fabulous (kinda like these). They're working on developing some new bags out of army canvas which look pretty stellar too. However, I'm even more excited about the newest material they'll be working with...fire hose! Cannot wait to see what Teamwork comes up with!
