Moisture-Wicking Performance

Pulls sweat away from the body

The gear closest to your body has to be built right. Thin, cheap rash guards break down fast — they lose shape, lose compression, and stop protecting you when you need it most. Every ONX product is built around solving real problems fighters face in training. This rash guard starts with 300 GSM fabric because anything less isn't built for serious work.

Every ONX product is designed to help athletes perform at their best. This rash guard was built to protect your skin, support your muscles, and hold up through the demands of real combat sports training — from BJJ and MMA to wrestling, functional fitness, and beyond. Heavy-duty compression that works as hard as you do.
