I have this bag and it works out great for me. Pretty good bit of space and goes on and comes off very easy. I commute to work (150 miles round trip minimum) daily and keep my rain gear hard hat and drinks in it. Get to where I am going, loosen 2 quick release straps and carry it with me. Hope you have as good of luck with it as I do.I went to Wal Mart today and found the MC backpack and it is 1 nice piece.It is made By Fieldline abnd comes in several colors and has a few reflective strips also.We will see how it works this weekend.
