    The Narwhals are a powerful tool for combating heat-illness. 

    We have used the Narwhals every game for the last two seasons and will continue to do so.

    The Narwhals have made a major impact on thermoregulation for our parasport athletes.

    Every training room and weight room on the planet should have the Narwhals!

    I have seen measurable improvements in my strength, training volume, and recovery.

    The palm cooling technology is especially useful for us here in Arizona, where we’re often training in 100+ degree heat.

    Why Cool Your Palms

    Our palms are like radiators for our body. They get 10X the blood flow compared to other skin areas. By holding something cool (not cold) you quickly remove heat and cool down fast.

    Easy Setup

    The Narwhals can be set up hours before use. Set up takes just 60 seconds.

    Optimized Cooling

    The innovative design stays at the correct temperature and avoids thermal barriers.

    Long-Lasting

    Keeps cool for 2+ hours of use even in hot conditions.
