Well I disagree with it hurting you, it might depending what's in it.
My Mountain bike backpack, which also has a Camelback (water bladder for drinking),
actually cushioned me in falls. I use it on my motorcycles when I go on extended rides.
It's nice to have a drink at your leisure when riding, especially on dusty trails.
Check out your local bicycle shop, they have some nice choices that fit well
with a waist strap that keeps them stable.
