I had just ordered a set of the Enduro rear tail bag straps, for use with my alfa-beta bag, that I just bought. I ordered that(straps) and a new harness for my enduro tank bag, directly from Wolfman.
Maybe Eric can answer better, but the alfa-beta bag and the enduro tail bag are at the same price point, but the enduro comes with the mounting straps and a rain cover. I wondered why the alfa-beta bag did not come with these??
I ordered the alfa-beta bag over the enduro one, just for the width. The alfa-beta bag is 20" wide wihile the enduro was 16". I needed the width for my sleeping pad, which is 20" wide. I did not want to bend it in half.
