Good and bad
I’ve owned this over 6 months and day hikes with it often. I love the pockets. Side, shoulder strap, and big shove it on back. Bungee straps on back have been handy. Double chest straps are annoying. Waist belt is not designed well and doesn’t help carry pack weight. So it’s all on your shoulders. Pack rides close to back and has zero ventilation so I often have a very wet back from perspiration, The fit is not as good as an osprey.

Great high capacity running vest
Yes , I recommend this product
This isn't a day pack, its a large running vest -- a fact which the other review seemed to miss. It secures tightly to your upper torso like a running vest and does an impressively good job for its capacity. The strap doesn't go around your hips because it's not a hip strap, it goes below the ribs for stability while running. It's big enough that I can fit an ultralight backpacking kit and 1 day of food, and is stable enough to run with it. Basically, its a great fastpacking pack.
