Not sure when this ends or if it is store specific - Liverpool Area NSW. Went to bigw yesterday and spotted these 'life' guards for cricket players. Can be used for paint balling protection too.
Will not be everyone's choice I guess for the perception that $2 brings to mind regarding protecting your 'treasure'. They are pretty sturdy though and have good padding all around.
There were 8 or so left when I was there.
I am sure some of you genius people will think of other creative uses for this.
