that looks pretty rugged there Chaos,.. my only issue,.. if you crash, and get really hurt to get to the phone and use it might be impossible. where attached to the shoulder strap of a pack it's always with you, isn't going to get damage (the indent in muscles between your chest and shoulder isn't a place you land on ) and can be used easily even if injured... Just saying. It has happened to me and the bike was WAY to far away after for me to be able to call out on if the phone was attached to it not me.
