I just returned from a trip to London where I used a bag similar to this.  While I love Baggallini bags for their light weight and organization capabilities, there was one feature that I found to be a drawback.  Since the weather was warm, I did not need to wear a jacket and wore the bag cross-body over lightweight tee shirts.  The canvas strap has very rough edges, and as I walked (many miles), the strap literally sawed a sore spot on my neck.  While the strap is definitely sturdy, which is an advantage on crowded subways and buses, I don't think I would carry this bag again unless it is over a jacket or coat with a collar between the strap and my skin.  I notice that some other Baggallini bags have the strap made of the same nylon as the bag - I think if I buy another I will definitely look for one with a strap like that instead of the heavy nylon canvas.
