Do you need to have a red and blue singlet for freestyle? My son has decided to wrestle freestyle this year and we only have a blue one, since he will only be able to wrestle in 2-3 tournaments I didn't want to have to run out and buy another one.

The rule book calls for a red or blue singlet, u can buy a reversable one as well,,my son has a red and then a blue one,,lots of closeout specials this time of year

well it depends on which tournament you go to. The smaller ones they would like you to have but if you don't they alwasy have leg bands. If you go to bigger ones then they will almost certainly require either reversable or red & blue singlets.
