Is necessary to remove all zippers, if the flak vest/cummerbund/boots end up covering up a majority of them on the suit? Also is it okay just to remove the zipper tabs and sew the zipper seams together? My suit has many zippers and it would be impossible to remove them safely. There is also a pocket for a knife. I will post pictures later of the flightsuit but I do believe 90% of the zippers will be in spots that will be covered by the hard armor, boots, and the cummerbund, and potentially the thigh patches and mud flap.
