SWMBO gave me a Fishpond Sagebrush vest for B-day. Pros: you can carry mucho stuff, including large fly boxes, extra spools, etc. and you can hang things damn near everywhere. Con: you can carry TOO much stuff. That said, I like it for summer: it's almost entirely mesh, so it stays cool and, loaded judiciously, it's relatively light. Plus, given the source, I'd BETTER wear it
(and don't mind a bit).
