I purchased this for myself, along with the Magic for my girlfriend. I was looking for something smaller and more mobile than my Camelbak MULE NV for light and fast day hikes. Just looking for small minimal gear, some snacks, phone, keys, maybe a shed layer; yada yada yada. Well I found everything I need in this little guy! Holds everything I need, with good hydration capability, and room for an additional H20 bottle if you want to push the limits. I was looking to keep mobile, and light. This pack does just that!
