Bring power, precision, and composure to the mats with the Signature Cold Blooded Rash Guard – Black Venom (Athlete Edition). Built for driven youth athletes, this long-sleeve rash guard features a fierce serpent-and-skull design—capturing the mindset of staying calm under pressure and striking with purpose.
Made from smooth, high-performance four-way stretch fabric, this rash guard delivers full mobility for no-gi jiu-jitsu, wrestling, MMA drills, and high-intensity conditioning. Flat ergonomic seams protect against irritation, while the extended torso and sleeves maintain secure coverage during scrambles and fast-paced transitions. The vivid snake-and-skull artwork is fade-resistant, keeping its bold look through countless rolls and washes.
Part of Roll Gear’s Athlete Edition Collection, this design was inspired by one of our standout youth competitors—a No-Gi Pan Silver Medalist and multi-time champion across regional circuits. His relentless style and calm, calculated approach to competition inspired the Cold Blooded theme, representing discipline, mental toughness, and the heart of a rising champion.
Calm. Dangerous. Cold Blooded.
This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
