Frequently Asked Questions

What are the micro-mesh underarm panels for?

The micro-mesh panels are strategically placed at the underarms — the highest heat and moisture zone during training. The mesh construction allows maximum airflow at these points while the rest of the shirt provides close-fitting compression. The result is significantly better temperature regulation during high-intensity bag work, pad rounds, and conditioning circuits compared to a standard long sleeve.

Can I wear this on the mat for grappling?

This is a long sleeve training shirt designed for gym conditioning, striking training, and warm-ups. For mat-based BJJ and MMA grappling, a compression rash guard protects better against mat burns, stays in place during rolls, and dries faster. Use this shirt for bag work, warm-ups, gym conditioning, and post-training wear.

What is the sizing guide?

Sizing runs true to standard athletic fits: S fits chest 36–38 inches, M fits 38–40 inches, L fits 40–42 inches, XL fits 42–44 inches, and 2XL fits 44–46 inches. The 13% elastane ensures stretch and recovery through repeated wash cycles.

How do I care for this shirt?

Machine wash cold with similar colours and tumble dry on low, or hang to air dry. The silicone-lined crewneck and waistband maintain their shape and elasticity with regular washing. Avoid fabric softener, which degrades moisture-wicking performance in polyester-elastane blends over time.
