One of the parents at my club have started a company recycling old sports kit, especially relevant when kids grow out of boots after half a season of play.
Individuals post their kit on the website, set a price, some goes to the club, the some to the company.
Unlikely to make a fortune, but it might help famiies on a tight budget and good to see decent kit find a new home.
