Technical Suits in Age Group Swimming
Children under 10 years of age do not require a tech suit and for teens, only a consideration when they are qualifying for bigger meets. Tech suits are now banned in age group swimming in some US states.
Please don't feel you need an expensive tech suit and if your swimmer does have one, don't use them for meets under ACT championships.
