If you're like me, when you go for a quick run or bike ride, you don't need to carry anything big like a lumbar pack, but you still want to bring along important things like money, keys, an ID, tissues, or your cell phone. Check out this Nike Running Arm Wallet/Phone Case ($10). It'll keep little things safe so you don't have to carry them in your hand or deal with them bouncing up and down in your pocket (or worry about them falling out). This little pack can wrap around your arm or wrist, and since it's got a velcro snap, it'll fit snugly so you can slip it on and forget about it. I also like that the opening is secured with velcro, so you can access your stuff easily. Not bad for $10. Buy one here.
