First time contributor - woo hoo! :) I just received my order from Tom Bihn, and I gotta tell ya...these bags rock. I have used many different brands of bags, but the true test of what is made the best is the one you come back to. Tom Bihn is that bag. I am the proud owner of a large cafe bag in kelly green (lots of compliments on the color), and just ordered (and received the very next day) the medium cafe bag and Ruc's sack.
About the medium bag - I plan to use this one on the weekends. It's smaller than my large cafe bag, but will still hold a few magazines, wallet, checkbook, loose papers, bills, keys and small stuff. The small stuff (bandaids, rolaids, portable tooth brush) I keep in my medium Tom Bihn organizer pouch. These things are almost as indestructible as the bags. Totally cool.
About the Ruc's sack - this is a small backpack, and I plan to use it when I need to take my camera with me on the weekends in the place of my medium cafe bag. I can put all of the stuff from my medium cafe bag, as well as my Sony digital camera (it's kind of bulky). Fits in the backpack just fine.
I use the large cafe bag for everyday use to and from work (downtown Seattle). I recently moved from Texas to Seattle, and this bag has been everywhere. From the annual tulip festival in northern Washington state to the beaches, over the mountains, you name it. This bag is so well made that it shows absolutely no signs of wear. And I am not one of these people who doesn't use the bag. I'm in and out of this thing all of the time. And it is perfect. I get so many compliments on the style of the bag. I really have to hand it to Tom Bihn and Company - I am a customer for life. Thanks for a great product.:D
