Farnam Endure Sweat-Resistant Fly Spray
Farnam Endure Sweat-Resistant Fly Spray is prized for maintaining repellency on horses that sweat during work or in hot climates, delivering steady protection when many other sprays wash or rub off. Against the stronger insecticidal concentrates here, Endure trades some raw knockdown power for a technical advantage in adhesion and longevity on sweaty animals, offering a cost-effective choice for active horses and riders who need protection that stays on through exercise.
