"Versatile and perfect" (Posted on 03/11/2016)
There's a perfect pocket in the front which hold my Iphone in a firm grip. ...pockets on the sides and rear.
If you are a runner/hiker that enjoy long hours out there, - this is it. I cannot imagine how they can make them better than this!!!

My only complaint is that i think that the ridges on the back panel could be a bit deeper, as my back still gets hot and sweaty, but not as much as with a normal backpack. Apart from that , its a brilliant bit of kit.
