Ingredients / Material How to Use

The Opti-Force mask has been crafted for your horse’s maximum protection and comfort. Our Clear View Vision mesh shields your horse from harmful UV rays. The tear-resistant material is highly durable and lightweight.

Fitting and Care Tips:

  1. When putting the mask on your horse, approach from the left side. Directly approaching your horse with the mask could startle them.
  2. Open the two locking fasteners and place the ears through the mask with the forelock over the trim and mesh. Secure both locking fasteners under the jaw.
  3. Once the mask has been fastened with the right amount of snugness, check each side of the horse’s face by allowing your fingers to slip comfortably between the mask and your horse. The mask fabric should not be too close to your horse’s eyes; ensure that the eyelashes do not poke through the material.
  4. Straps can be adjusted for a custom fit. Checking the mask daily is recommended. Examine the condition of your horse’s face and eyes. Check for any damage to the mask. Replace the mask if damage is found, as it is difficult to repair. It’s important to keep the mask clean. Wash the mask periodically with mild soap and water.

Repellency to mosquitoes remains effective for six months of exposure to weathering for nonwashable items such as tents, tarps, awnings, patio umbrella covers, kennel covers and stall covers. Repellency remains effective for 25 washings for washable items such as sleeping bag covers, backpacks, outdoor furniture covers, outdoor furniture cushion covers, netting, blankets, ground cloths, horse blankets and pet bedding.

It is a violation of federal law to use this product in a manner inconsistent with its labeling. Wash separately from other items.
