I love the Alps vest, but found the seat to be absolutely terrible. It was the second thing I took off of the vest, right behind the kickstand. Providing you've had a Cabela's tat'r vest in the past (seems most people have), you don't have to modify anything if you don't want to. The male buckle on the tat'r seat will fasten right into the female buckle on the Alps vest. I have used this combination for several years, and feel it is the best of both worlds.
