Not sure I get the fear of wearing gamers out in public.
Granted I am not wearing my best gamers out, but I almost exclusively wear game worns to games.
I don't eat during the game I eat before and when I do I take my jersey off...simple.
Yes, I have had a beer spilled down my back by the drunk behind me. Got home, washed the jersey on delicate cycle and back
to the way it was before the spillage.
The only real risk of washing out wear is if the jersey hasn't been washed since the wear(stick mark) was added to the jersey.
I purchased a game worn and was handed the jersey immediately after the game. The jersey was drenched and there was no way that sweat soaked
jersey was hanging next to my other jerseys. There was a stick mark on one of the back numbers that faded even though I washed the jersey without detergent.
Had I not picked up the jersey after the game it would've been washed by the team and the stick mark would've been gone anyways.
Exercise a little care and enjoy your jerseys...isn't that why you purchased them?
