If you like training in a t-shirt rather than a tight-fitting rashguard, then you need to give the GenX grappling shirt a try. It's made from a high quality polyspandex material that will breathe when you train in the heat without weighing you down with cold sweat in the winter. All stress points have triple-stitched seams so the shirt isn't prone to tearing during rolling sessions. The torso has been extended so it won't ride up easily, and the print is top quality so it won't peel or crack easily.
