I just received my new Late Season pack. I wear size 34-36 jeans so put down a 35" waist on my order. When I strap the waist belt, there is no slack left to grab onto to cinch up, the end of the belt is all the way against the plastic power pull retainer. How much distance should there be when the belt is cinched up between the padded belt ends? I am thinking I need a larger belt? Let me know if what I am asking is not clear.
