For those of you who own or have tried on this style, what are your thoughts? There were posts several weeks ago with some new bags. Since then, I've noticed a couple on eBay (1 or 2 may have been from PFers). Recently, I haven't seen much about it here. One concern I have is that it may be a bit too rectangular, especially at the top. I think it's better to have a rounded in shape at the top to conform to your body (although maybe this style slouches with time). I'd love to hear any comments.
