Not sure if this is quite the right place for this, but...
I occasionally run home from work. I more occasionally run to work (OK, I've done it once). I'd like to be able to do it both ways but that probably means carrying things, such as lunch. I have a small rucksack which is just about big enough for the job, but it was very cheap, doesn't sit well when I'm running and the shoulder straps rub my neck above my running shirt collar.
Any suggestions? I don't need a Camelback type thing. I don't run far enough to need to take water with me. But if that's the best answer I wouldn't be against it.
Thanks
