What does “Ranked” mean and why are the colours Black, Blue, Brown, and Purple?

The Ranked series uses BJJ belt rank colours — each colourway represents a milestone belt in Brazilian jiu-jitsu progression. The colour you wear can reflect your rank or simply your personal preference. The four available colours (Black, Blue, Brown, Purple) correspond to the four adult BJJ belt ranks above white, making them a natural choice for practitioners who want their gear to match their rank.

Is a long sleeve rash guard better than short sleeve for grappling?

Long sleeve rash guards provide full-arm skin protection against mat burns during ground work, which many grapplers prefer for intense drilling sessions. Short sleeve guards offer more freedom of movement and run cooler for hard rolling rounds. Most serious BJJ practitioners own both — long sleeve for drilling and mat-heavy training, short sleeve for live rolling and competition. The right choice depends on your training intensity and personal comfort.

Can I wear this rash guard under a gi?

Yes — the athletic compression fit is designed to layer smoothly under a gi jacket and pants without bunching. Wearing a rash guard under your gi provides skin protection, moisture management, and a hygienic barrier between your skin and the gi. Many BJJ competitors wear rash guards under their gi for both comfort and competition compliance.

How should I size a compression rash guard?

Compression rash guards should fit snugly against the skin without restricting breathing or shoulder movement. A proper fit has no excess fabric that could be grabbed during rolling, but should not feel constrictive at the torso or armpits. Refer to Hayabusa's size chart using chest and torso measurements — if you're between sizes, most grapplers size down for a tighter competition-grade fit or size up for a more comfortable training fit.
