Hayabusa Rash Guard Long Sleeve Core Black

For athletes seeking maximum protection during BJJ, MMA, or no-gi sessions, the Hayabusa Rash Guard Long Sleeve Core Black is the ideal choice. It combines sleek, technical design with compression, breathability, and full arm coverage — offering reliable protection in every training scenario without sacrificing movement or style.

Built for Intense Training

In no-gi rolls, MMA drills, or clinch work, skin-to-skin contact is unavoidable. That’s why this long sleeve rash guard provides added coverage, shielding your arms from mat burns, friction, and irritation. Its compressive 4-way stretch fabric gives you the flexibility and support you need for armbar setups, guard retention, and fluid transitions.

The long sleeves keep your shoulders and arms warm, which helps prevent injuries during cold sessions. It not only protects your skin but also stimulates blood flow and supports joint mobility — essential for serious training.

High-Performance Fabric

Constructed from a premium blend of 75% polyester and 25% lycra, this rash guard is light, breathable, and elastic. Polyester adds strength and durability, while lycra ensures a snug, responsive fit that recovers after every movement.

Sweat is quickly wicked away across the entire upper body, keeping you cool even during fast-paced scrambles and takedowns. The fabric dries quickly, so you're ready to move straight into conditioning or strength work without switching gear.

Functional Fit and Finish

Compression is about more than looks — it supports your core and arms during explosive movements and reduces fatigue in long sessions. This rash guard hugs your torso and arms tightly while allowing you to breathe freely, which is crucial during sparring and performance rounds.

Flatlock stitching lies smoothly against the skin, preventing chafing and irritation even during extended wear. Reinforced areas around the shoulders and underarms improve durability where grappling stress is highest, making the Hayabusa Rash Guard Long Sleeve Core Black a true training essential.

Grip and Stability on the Mat

The silicone anti-slip waistband keeps the rash guard in place throughout intense ground exchanges. It prevents the shirt from riding up, maintaining consistent compression and ensuring zero distractions during your rolls.

Minimalist Design, Maximum Focus

The black color gives a clean, professional look — perfect for focused athletes. Hayabusa’s minimalist design avoids flashy prints or loud branding, making it ideal for serious training environments. The black tone also complies with IBJJF rules for no-gi competition (subject to belt-level restrictions), allowing you to use this rash guard for both practice and tournament day.

Despite its simplicity, the bold black hue exudes discipline, control, and intensity — helping you show up with confidence.

Reliable for Daily Training

If you're training several times a week, you need gear that keeps up. The polyester-lycra fabric remains strong, flexible, and form-fitting — even after many washes. The compression stays consistent, seams remain intact, and the black color keeps its depth without fading or pilling.

Whether under a gi or worn alone for no-gi, this rash guard fits smoothly without bunching, making it perfect for versatile training routines.

Comfort and Warmth in Cold Conditions

Long sleeves don’t just protect your skin — they also help regulate temperature. This rash guard helps keep your core and arms warm, promoting joint mobility and reducing injury risk during cool-mat sessions or early-morning classes.

Pair it with thermal leggings or compression gear for full-body coverage in colder gyms or ventilated training areas.

Easy to Maintain

After hard training, this rash guard is easy to clean. Wash cold with similar colors, air dry or tumble dry on low. Avoid bleach or fabric softeners to preserve the fabric’s elasticity and structure. With proper care, your Hayabusa Rash Guard Long Sleeve Core Black will perform session after session.
