FLAIR Strips provide a spring-like force that gently supports the nasal passages and reduces soft tissue collapse that causes narrowing of the airways during exercise. The Strips support the nasal passages including the nasal valve, which is the narrowest part of the nasal passages, to make breathing easier. When horses breathe hard during exercise, the soft tissue over the nasal passage is sucked in, reducing airway diameter and restricting airflow. The spring-like action in FLAIR Strips gently support the nasal passages to reduce soft tissue collapse and make breathing easier. FLAIR Strips don't help horses breathe in more air. The Strips help horses take in the same amount of air but with less work. For example, think about the difference you feel when breathing through a stuffy nose vs. when your nose is clear. When your nose is stuffy, the nasal passages are narrower, making it more difficult to breathe. Breathing easier helps horses at all levels of fitness and skill maintain respiratory health and optimum performance. Many riders also report that horses wearing FLAIR Strips are more relaxed and focused.
