I love this small backpack, it just fit for any thing. I use it for running to/from work, cycling, traveling, and hiking.
Pro : The best part is the “3D Air Mesh” back fabric, which allow air flow on the back. It separate my back to the pack, allows my body to breathe and not soak in the sweat to the backpack, yet it keep the pack hold on to my back and not interrupt my activity. It also has a quick release loops for hiking poles, I use them for bike helmet or lock. The top compartment is very convenient to be accessed when I am on the bike or in the run. Its internal packing strap is very useful to make your pack more compact. I also use it as a strap for quick storage such as jacket, blanket etc. It also has a rain cover that is stored on the bottom pocket.
Cons : I wished there is more padding on the bottom part of the back and also on the waist loop. When I use it for running, it cause a minor chaffing on my back.
