How big of a fellow are you?
I am a small guy, and a lot of the vests I liked did not fit, nor could they be made to fit me... "One Size Fits All" means it will not fit me.
I went with the Cabela's Tat'r simply due to the sizing, but admittedly, am very satisfied with the vest.
I hunt some steep areas with long walks, and when I kill birds, I am generally walking uphill to the vehicle (due to the parking/driving availability). The only reason I stick with a vest is due to my preference for carrying a bird a long ways uphill in a vest as opposed to a tote or over-the-shoulder.
