My OR backpack with tennis rackets inside sits up just behind my head. It's only 11 inches wide, though, so I think I can look over my shoulder OK. Haven't tried it on the bike yet.

I picked this bag because it was the smallest, lightest backpack that would fit my rackets. It isn't a perfect fit. The bag is 24 inches tall with the top rolled shut. My rackets are 27.5 inches long. My plan is to leave the top gaping open. In that configuration, the bag is a couple inches taller than my rackets.

Only thing I could say against the bag is that it is top loading only. I'm OK with that, but I can see how some people would want easier access to the stuff on the bottom. It is a tall skinny bag with an 11x9 inch hole at the top.
