ALL-STAR Adult AFx Fastpitch Catching Kit. The X-Factor is here. AFx by All-Star is a game changer. Protective and comfortable, yet fitted and streamlined, it's all about maximizing performance with All-Star's new elite line designed for women. The AFx leg guards incorporate our patented LINQ™ technology, which keeps the leg guards in place through every block, throw, and squat. Our AFx chest protector has been reimagined to include break points tailored to a woman's curves. Its unique shape delivers a fitted, yet protective feel, while a simple harness design allows for easy adjustments and quick transitions between innings. Our popular MVP Series helmet is built with durable ABS plastic and is lined with removable, breathable mesh padding. This AFx line is a perfect match for elite fastpitch catchers who demand every advantage.
