OG Old Guy Jiu Jitsu Short-Sleeve Rash Guard

Experience beats youth, technique beats speed—and complaining about your back is just part of the warm-up.
The OG Old Guy Jiu Jitsu Rash Guard is made for seasoned grapplers who have forgotten more submissions than the young guys have learned. Its clean black design features a gold OG chest logo and an oversized Old Guy Jiu Jitsu graphic across the back.
Built with smooth, flexible performance fabric, this short-sleeve rash guard moves comfortably through drilling, rolling and the occasional five-minute round that somehow feels like a mortgage payment.
Because you may need extra time to stand up—but once you get on top, these kids are staying there.
Features:
• Athletic compression-style fit
• Smooth, flexible performance fabric
• Short sleeves for unrestricted movement
• Flat seams designed to reduce rubbing
• Small gold OG chest logo
• Large Old Guy Jiu Jitsu back graphic
• Ideal for BJJ, grappling and no-gi training
Fit note: Rash guards are designed for a close athletic fit. Consider ordering one size larger if you prefer a more relaxed feel.
Train smart. Apply pressure. Remind the young guys that beatings are free—but respect is earned.
