Without physics, there would be no BJJ. From the torque in your kimuras to the downward force of your side control and the fulcrum in action during your kneebars. It's all science.

Cleverly captioned with the basic physics formula for force, Force = mass x acceleration. If you've been on the receiving end of a solid Uchi Mata, then you know how brutal this "force" can be. Speaking of equations, this shirt plus this price = unbeatable.

Printed on 100% combed cotton, 32 singles for extreme softness. Standard, slightly relaxed fit.
