I just got a Class 3, level two safety vest/shirt. The warning label inside advised that it, and the mass of 3M bright silver reflective tape on it should be washed no more then 25 times before replacement. The bottom edge of the label even had the numbers 1 through 25 and advised users to mark the numbers one by one each time the vest was washed. Have a look at your own gear and think if it shoould be replaced.
