FAQs
How does the Omni-Freeze ZERO technology work?
It uses blue cooling rings on the interior of the fabric that react with your sweat to trigger a cooling sensation.
Can I wear this for casual everyday use?
Yes, it is comfortable for casual wear, though the cooling effect is most active during physical exertion.
Is this shirt suitable for very cold weather?
Because it is designed to wick moisture and cool the skin, it is best suited for warm to hot conditions rather than cold weather.
Does the fabric provide UV protection?
The shirt is designed primarily for moisture management and cooling; check the specific product tag for UPF ratings if sun protection is your primary goal.
What is the best way to dry this shirt?
For best performance and to extend the life of the fabric, air drying or tumble drying on a very low heat setting is recommended.
Troubleshooting
Shirt feels less cool than when new
Check if fabric softener was used, which can coat the cooling fibers. Wash the shirt with a small amount of mild detergent to strip residue.
Fabric holds onto body odor
Use an odor-neutralizing sports wash and ensure the shirt is washed immediately after use rather than leaving it in a damp gym bag.

Setup, Compatibility & Care
To ensure the longevity of the cooling technology, always follow the care label attached to the garment. Machine wash in cold water with similar colors on a gentle cycle. Use only mild detergents and avoid fabric softeners, as these can clog the microscopic cooling structures in the fabric, reducing effectiveness. Tumble dry on low heat or hang dry for best results. Do not use bleach or iron the shirt, as extreme heat may damage the synthetic fibers.
