I don't have anything that big, but Mat Monster / Ringside has store at their wearhouse just off I-35 by the big UPS distribution center in Lenexa. They have any type of singlet they have in their cataloge or on line and are really nice guys to work with. You can walk in and out with any new wrestling gear in minutes.
