Swimsuit Repair!

Maybe someone here knows the best way for me to fix my son's brand new Speedo Endurance+ team suit. He wore it for the first time to a meet yesterday and proceeded to rip about an inch-long hole (not on the seam) on the inner leg when he was playing on the playground. My other son managed to sit in gum but he will have to learn to live with a gum spot. What luck! Does anyone know of anything good to sew up or patch a tear? The suits are supposed to last two years and I hate flushing $30 down the toilet after one meet! Thanks!
