What is the difference between the T15 Long Sleeve and Short Sleeve rash guards?

The T15 Short Sleeve is lighter and cooler — better suited for striking-based training (boxing, Muay Thai, MMA) and warmer training environments. The long sleeve version provides full arm coverage, which is preferred for BJJ and no-gi grappling where forearm mat burns are common, and for outdoor training requiring UV protection. Both use the same polyester-spandex construction and flat-locked seam design.

Can I use this for BJJ and no-gi grappling?

Yes — the flat-locked seam construction and compression fit are suitable for no-gi grappling and BJJ training. The short sleeve design still protects the upper arms and torso from mat burns. For training where forearm protection is a priority, the long sleeve variant is the better choice. For competition, check sleeve requirements with your organisation before use.

Does it work as a standalone shirt or only as a base layer?

Both. As a base layer under fight shorts, it provides thermal regulation, protection, and coverage. As a standalone training shirt for bag work, pad drills, and conditioning, it performs well. The compression and moisture-wicking properties make it more functional than a standard athletic T-shirt for high-intensity sessions.

How should I wash it?

Machine wash cold on a gentle cycle and hang to dry. Do not use high heat in the dryer, iron directly over printed areas, or bleach. Wash inside out to protect the moisture-wicking treatment and printed design. Rinse after salt water or chlorinated pool use to prevent fabric degradation.
