I've had a WB Loader as a daily carry on my commuter for a few years. I really like the overall design - materials, size, features. There's just two minor things I don't like -
1) The front pocket REALLY needs a button or some other closure, I had my phone fly out and crack just hitting a small bump on a sidewalk. I've since added my own button without too much difficulty.
2) Where the large velcro strap covers the roll top it rubs a patch of bare cordura every time and has started wearing pretty quickly. There should be a piece of nylon or some other harder wearing piece covering that strip.
Can't be beat for the price, some of the other 137 totes are easily double the price.
