Opti-Force Fly mask

Protects against and repels mosquitoes, ticks, ants, flies, chiggers and midges. Innovative in the horse and fly mask category. Provides built-in, invisible, odorless insect protection.

Designed for secure fit with strong Clear View Vision mesh.

Features Insect Shield® Repellent Technology, which was originally developed in the 1990's in conjunction with the US Army and then used in the first EPA insect repellent apparel in 2003. The process binds a proprietary permethrin formula tightly to the fabric fiber. Technology lasts the expected lifetime of the mask (25 washings). Insect Shield received a Category IV rating, the most favorable rating given by the EPA. It requires no re-application and there is no potential for over-use.
