Hayabusa Rash Guard Short Sleeve Core Green

The Hayabusa Rash Guard Short Sleeve Core Green is built for fighters who train hard and demand more from their gear. Designed with durability, comfort, and smart technical features, this rash guard supports you during intense grappling, BJJ, and MMA sessions. Whether you're training daily or gearing up for competition, this shirt delivers consistent performance and protection.

Made for Grapplers & Fighters

The Core Green rashguard features a compressive, second-skin fit that supports your muscles while eliminating fabric drag. Its nylon-lycra construction offers 4-way stretch for full mobility without compromising structure or resilience. Whether you’re hitting takedowns, scrambling for position, or holding clinch control, this shirt stays locked in and moves with you—without bunching or riding up.

The short sleeve cut gives your shoulders total freedom, essential for underhooks, transitions, and submissions. You’ll never feel restricted, even during high-tempo drills or competitive rolls.

Lightweight, Breathable, and Fast-Drying

Designed for performance under pressure, the Core Green rashguard is made from lightweight, breathable fabric that wicks sweat and dries quickly. It keeps your body cool and your skin dry, even during extended mat time. You’ll avoid the sticky, overheated feeling that cheaper rash guards can cause.

This rash guard maintains comfort across all training intensities. Whether you’re grinding through drills, sparring full-contact, or doing strength work, it performs without compromise.

Durable Construction with Flatlock Seams

Built to last, this rash guard features reinforced flatlock stitching that lies flat against your skin, eliminating irritation and preventing rips. These seams hold strong under pressure—ideal for those who train multiple times a week or roll hard during open mats.

At the hem, a silicone anti-slip waistband ensures the rash guard stays in place. Whether you’re sprawling, passing guard, or transitioning from top to bottom, it won’t ride up or shift out of place—keeping your focus on performance, not adjusting your gear.

Clean, Focused Look

The Core Green edition stands out with a refined, minimalist look. The rich green color reflects calm confidence, discipline, and professionalism—no flashy graphics, no loud logos. The subtle Hayabusa branding enhances its clean design, making it appropriate for every gym setting.

This colorway also meets IBJJF No-Gi guidelines (provided it matches your belt rank), making it a competition-ready option as well as a training essential.

Built for Intensity

This rash guard is made to withstand frequent use, high-contact sessions, and repeated washing. Its nylon-lycra blend maintains stretch and shape, even after months of hard training. The stitching holds, the hem grip remains effective, and the color stays rich.

It’s the kind of gear you can rely on—day after day, roll after roll.

Easy Care

Machine wash cold with like colors. Air dry or tumble dry on low. Avoid bleach and fabric softeners to preserve the elasticity and performance of the material. With proper care, this rash guard will hold up for the long haul, offering the same feel and fit every time you put it on.
