Wearing sports underwear is about more than staying covered in the changing room – a good sports bra or undershorts will keep your child’s skin cool and dry (and help reduce sweat marks showing up on clothing), as well as provide support. They’ll also help with chafing during longer P.E or after-school sessions.
