Rashguard Fabric: Martindale Abrasion and Pilling Test

At FightBro, we test our fabrics the same way we test our gear: under real stress. In this video, our rashguard fabric goes through the Martindale abrasion and pilling test, one of the textile industry's standard methods for measuring how a fabric holds up to repeated friction.

The Martindale tester works by rubbing the fabric sample against an abrasive surface in a continuous figure-eight motion, cycle after cycle, simulating months of wear in a controlled setting. The result tells us two things: how resistant the fabric is to abrasion damage, and how well it resists pilling, the small fiber balls that form on lower-quality fabrics after repeated rubbing.

For a rashguard, this matters more than for almost any other garment. Grappling means constant friction against mats, gis, and training partners, session after session. A fabric that pills or breaks down quickly does not just look worn, it loses the smooth surface that protects your skin from mat burn.

This is part of how we develop every FightBro fabric: test, refine, and only put it into production when it performs. Watch the full video above to see the test in action.
