cheap fix....quivers are way overpriced these days....

used to have to do this for pultrudeds

moleskin/sight window pads....cut a strip like an inch longer than the distance from the first arrow gripper to the last....and however wide you need....take the backing tape off...lay it on top of the gripper...push it into the gripper slots with an arrow...sometimes you may need two..but one usually does the trick...when it wears down eventually (usually only did once a season)...put in another piece...
