ACTIVE SKIN 12

Unisex, fits petite frames and wide frames. I have tried a few and this is truly my favorite. Keep it light weight or option to add more water. Pocket on the back for rain coats etc. I use mine even on shorter trail runs. Perfect for hiking as well if you want to go hands free. Holds my phone, keys, rain coat, beanie, & more. Great for longer runs or shorter ones. Very versatile Pack. There is no bounce or movement it fits you truly like skin.
