So I'm the guy who designed this piece. The goal was to make a high quality piece that could both be used in the backcountry and in the front country. Powershield is the finest softshell material, it's made in Canada so the quality is the highest. I like the MP3 pocket on the inside and I put in a security pocket on the inside of the front right hand pocket. I can fit my crackberry, small wallet and keys in there and I don't stress about losing my stuff when I'm using the hand pockets and neither will you. The pocket on the arm is for business cards or whatever you need in a moments notice. It is a technical fit and looks great. Enjoy this piece as I am wearing it everyday.
