Does anyone know where to source small plastic belt buckles like the ones Sitka build into their pants? I can't stand anything over a 1" belt strap and need a nice flat profile buckle to fit under my pack. I have one belt that came with a pair of Sitka pants years ago with the perfect buckle but can't seem to find where to source something similar. Looking for a buckle like the top one in the below picture. 1" strap with easy clip and tighten abilities. All belts these days seem to be huge and bulky to fit the "tactical" fad.
