It's been 25 years since a brand innovated male swimwear.

That ends now!



A3 Performance FitLock Male Swimwear Drawstring Lock Technology
Lock your suit in place before you race!


A3 Performance’s newest technology innovates male swimwear unlike anything ever before! FitLock Technology is the first-ever FINA approved swimsuit drawstring lock.

Guys, say goodbye to the hassle of a swimsuit drawstring that loosens during a race or training, forcing you to untie and retie again and again. Now you can tighten your suit with one tug and prevent it from coming loose!

Featured on VICI, A3 Performance's elite technical racing jammer, and NOVA, our newest FINA and USA Swimming-approved racing jammer, FitLock is a proprietary technology designed and developed by A3 Performance. It is a small lock on the drawstring that holds it in place to secure your fit so you can focus on swimming fast.

Before diving into the water, lock your drawstring in place by simply pulling both drawstrings until you reach your desired tightness. Once your desired tightness is achieved, tie your drawstring as you normally would and tuck your strings into your jammer.

When you are done racing or training, untie your suit (if it hasn't already come untied itself), pinch the sides of the FitLock, pull, and voilà your drawstring is loosened.
