For a challenging practice, fit your snorkel with the Tyr Ultralite Snorkel Airflow Restrictor Set. Using the same concept as a hiking mask, this add-on limits the amount of oxygen allowed through your training snorkel for a harder training session. Ideal for competitive swimmers, this item minimizes your airflow during practice so that you can perform at the top of your game without it during swim meets.

• Restricts airflow in your TYR Ultralite snorkel
• Adjustable for different levels of restriction
• To be used with Tyr Snorkel ULTRALITE
