Hayabusa Rash Guard Short Sleeve Core Black

The Hayabusa Rash Guard Short Sleeve Core Black is built for serious athletes who train hard and expect their gear to work just as hard. Whether you're grinding through daily BJJ rolls or pushing limits in MMA sessions, this short sleeve rash guard offers the perfect blend of compression, breathability, and durability.

Designed for No-Gi, BJJ & MMA Training

No-gi training demands unrestricted mobility, reliable coverage, and lasting comfort. This rash guard delivers on all three. Its form-fitting compression design supports your muscles while minimizing friction and skin-on-skin contact. You’ll stay protected from mat burns and reduce the risk of skin infections—all while maintaining full range of motion during scrambles, takedowns, and submissions.

The short sleeves give you more freedom through the shoulders and arms—ideal for overhooks, underhooks, and dynamic positioning in grappling-heavy scenarios. You’ll move naturally and confidently from the first drill to the last round.

Premium Materials That Work as Hard as You Do

Crafted from a blend of 75% polyester and 25% lycra, this rash guard is lightweight, breathable, and flexible enough to move with you. The moisture-wicking fabric pulls sweat away from your body, helping to regulate temperature and keep you dry even during back-to-back sparring sessions.

The elastic fabric adapts to your body without restricting you. Whether you’re passing guard or defending submissions, the Core Rashguard stays in place, keeping your focus on technique—not your shirt.

Built to Last with Smart Stitching

Durability is a must, and Hayabusa delivers. Reinforced flatlock stitching lies flat against your skin and reduces chafing, no matter how long or intense the session. These seams hold strong under pressure, preventing wear and tear even after months of regular use.

The Core Rashguard also includes a silicone waistband grip at the bottom hem, a small but essential feature that keeps the shirt from riding up mid-roll. No more adjusting between rounds—this rash guard stays locked in so you can stay locked in.

Clean Look, Competition-Ready

Sleek, black, and free from flashy designs, the Hayabusa Core Short Sleeve Rashguard keeps things professional. It’s IBJJF-legal for no-gi tournaments (as long as it matches your belt color requirements), so you don’t need separate gear for training and competition.

This understated design pairs perfectly with any shorts or spats and reflects the mindset of a focused athlete—no gimmicks, just performance.

Easy Care for Frequent Use

High-level training demands low-maintenance gear. Wash this rash guard in cold water with similar colors, then hang it to dry or tumble dry on low. Avoid bleach and fabric softeners to maintain elasticity and fit. With proper care, this rash guard will be a mainstay in your gym bag for a long time.
