Osaekomi Edition Long Sleeve Rashguard

Built for Pressure. Designed for Control. Inspired by the discipline of Osaekomi — where progress isn’t forced; it’s applied. The Osaekomi Edition Rash Guard represents the mindset of staying heavy. It’s about not rushing, not reacting, and applying constant pressure until movement breaks.

Dominance isn’t loud. It’s earned through control.

Engineered for Maximum Protection

Built for hard rounds, constant contact, and the positions where pressure matters most. The long sleeve design provides full-arm coverage to protect against mat burn and friction, acting as a durable second skin during high-intensity training.

• Locked-In Compression: Stabilizes muscles and reduces fatigue during explosive transitions and heavy pinning.

• 4-Way Stretch Fabric: Engineered for zero-restriction movement. Your gear follows your intent in every direction.

• Extended Silhouette: A longer cut in the body and sleeves designed specifically to stay in place during the most intense scrambles.

• Total Mat Protection: Full-sleeve construction to shield your skin and maintain hygiene through the longest sessions.

Technical Specifications

• High-Density Fabric: 225–230 g/m² performance weight — a substantial feel that offers superior durability and "snap-back" recovery.

• Reinforced Flatlock Seams: Low-profile, high-strength stitching to eliminate chafing and survive extreme tension.

• Sublimated Graphics: The Osaekomi artwork is fused into the fibers. It will never crack, peel, or fade, no matter how much friction you apply.

• Integrated Protection: UPF 50+ rating for outdoor cross-training and sun protection.
