Cashel Fly Mask Extender - 5 Inch Hook-and-Loop Jaw Extension

Fix Tight Jaw Straps Without Buying a New Mask

If your horse's fly mask fits perfectly around the eyes but pinches at the jaw, you don't need to replace the whole thing. The Cashel Fly Mask Extender adds five inches of adjustable length to the throatlatch or jaw strap, solving fit issues for horses with wide jaws or thick throatlatches without compromising coverage or protection.

Built with the same heavy-duty materials as Cashel's Crusader line, this extender uses industrial-strength hook-and-loop to bridge the gap between too tight and just right. It keeps the mask positioned correctly for full UV protection and fly defense while your horse grazes, rolls, and moves naturally during turnout.

Why Riders Choose the Cashel Fly Mask Extender

Frequently Asked Questions

Q: Will this extender work with fly masks other than Cashel brand?

Yes. The Cashel Fly Mask Extender uses a universal hook-and-loop system that's compatible with most major fly mask brands, including Farnam, Kensington, and others with standard Velcro strap closures. As long as your mask uses hook-and-loop fasteners, this extender will integrate seamlessly.

Q: My horse wears a Cob-sized mask for the eyes but needs more room at the jaw — will this work?

This is exactly the scenario this extender solves. You can keep the smaller mask frame for a clear field of vision and proper eye fit while adding the necessary length at the jaw for comfort and security. It's a common fit issue for horses with refined heads and strong jaws.

Q: Does adding an extender affect how well the mask stays on during turnout?

Not at all. The heavy-duty hook-and-loop closure is designed to stay firmly in place once adjusted, even during high-energy turnout, rolling, or play. The extender maintains the mask's position and doesn't compromise security or coverage.
