The navel/waist belt included with the Over/Under Upland Vest (S-XL) measures about 50".
The navel/waist belt included with the Over/Under Upland Vest (2XL & Up) measures about 60".
For some Chief Uplanders, that may not be long enough, especially when layering clothing underneath on those cold weather hunts.
Since the waist belt on the vest is movable/removable, you have the option to replace it with this extra long waist belt, which allows for up to 70" when buckled. Your original buckle and webbing keepers can be transferred from the original belt to this longer belt.
