Unrivaled Comfort

We use buttery smooth flatlock stitching that doesn't itch and irritate.

Slightly extended cut means that your rashguard won't ride up while you roll.

Ventilated mesh armpit vents allow you to get through the toughest training rounds without overheating.

Built to Last

Sublimated graphics won't fade or peel as you roll or wash your rash guard.

Competition rules require that you wear a rash guard with at least 10% of your belt rank.
