This sling backpack rocks. I am able to put everything and have space for more. I used a regular backpack but with a backpack you have to take of your shoulders to get in it. I am not one for wearing on the chest either, with a sling you can slide it around then back on your back. This company has real nice colors. The sling has so much room and it is still not heavy. You got to try this company first before any others you will be very you did.
