I've been using the same Fox40 for 2+ seasons now and it's still in excellent condition. I do wash it with soap/water after every game to avoid the gunk build-up.
BTW, periodically I dream I'm officiating
...I blow my whistle, no sound comes out
...everyone looks at me
...I realize I'm naked and drowning and haven't done any homework all semester
...and then I...okay, too much info...take meds
...I'll be quiet now.
