Enter training mode with sharp focus and controlled aggression in the Signature Cold Blooded Rash Guard – Black Venom (Athlete Edition). This adult short sleeve rash guard showcases the striking serpent-and-skull artwork from the Cold Blooded series—capturing the mindset of staying calm under pressure and striking with precision.
Crafted from smooth, sweat-wicking four-way stretch fabric, this rash guard provides full mobility for no-gi jiu-jitsu, MMA, wrestling, fitness training, and conditioning. Flat ergonomic seams reduce irritation, while the fitted cut keeps the rash guard secure through scrambles, takedowns, and fast-paced movement. Lightweight, breathable, and fade-resistant, it’s built to perform at the pace of serious athletes.
Part of Roll Gear’s Athlete Edition Collection, this design is inspired by one of our rising youth competitors—a No-Gi Pan Silver Medalist and multi-time champion across regional circuits. His cold, calculated approach to competition shaped the Cold Blooded theme, representing discipline, composure, and the ability to remain dangerous under pressure.
Sharp. Focused. 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!
