The Fighter Warehouse is an MMA store that is expanding with the growth of the MMA industry. They have two regular stores in Tampa, Florida and Selden, New York. They also have an online store at fighterwarehouse.com.
In addition to a plethra of t-shirts and other apparel, the Fighter Warehouse features MMA gear like fight shorts, mouthpieces, gloves, pads, gi's and rashguards. My favorite thing is the free shipping to the US and Canada. Check them out if you are looking for some MMA gear.
