Hey guys, I tried the search function but it came up blank. I just got a new pair of Flak Jackets, and one of the hinges squeaks whenever I open or close the arms. Any thoughts on how to stop this annoying squeak? I've sat there opening and closing them around 50 times, and while the squeak temporarily disappears, a couple hours later it has returned. Will they just quieten down in time and use? Thanks.
