Perfect Pack
This pack is perfect for normal long runs. It has the right amount of storage and is like your not wearing anything. When you first start off you know its there but once your a couple miles in it just fades away in the background and it just makes the run practical.

Great running vest
Good lightweight running vest with ample storage. Size runs a little small. May want to consider sizing up if you are going to wear any layers

Worth it
I debated about getting a cheaper vest versus this one. After a lot of research, I ordered this one. I just ran my first half marathon over the weekend. It stayed in place, I had no chafing from the vest, and it held everything I needed. 10/10 recommend

Great pack!
I bought this pack for my wife a couple of weeks ago. She has used it on road runs primarily, with a couple of trail runs as well. The pack is smaller, and fits her very well. It is not as comfortable on bare skin as the ADV SKIN models, but it has not caused any issues. This pack also has fewer pockets, but still plenty for any supported runs, and some non supported. Very pleased with this pack.

SO Good I Bought One For a Friend!
I borrowed this hydration pack from a friend, immediately fell in love, bought both the active skin 4 and 12 for the varying seasons and length of adventures here in NW Montana. In the summer, I can carry both squeeze bottles, the bladder, bear spray, collapsable bowl and treats for my dog, a light rain jacket, several SaltStick packets, gels/energy chews, and hiking poles comfortably in the 4. Clearly it was designed and tested to fit like a lightweight glove while still being versatile. The 12 is magically glove-fitting-like and lightweight also but can carry SO MANY clothes. I loved so much I bought the 4 for a friend who was also futzing with her pack and now she's a super fan.
