THE SCIENCE OF STAYING COOL
UPF 50+ Sun Protection That Helps Cool Your Skin, Too.
Icefil® combines UPF 50+ protection with patented cooling technology, so you can stay covered, comfortable, and confidently protected in the sun.
WHY ICEFIL® IS DIFFERENT
Sun protection is only half the story.
Cool to the touch, Icefil® goes further by helping deflect radiant heat and activating with moisture to lower skin temperature by up to 5°F.
Protection designed for the heat - not just the rays.
COOLING THAT GOES FURTHER
Cool from the first touch - and designed to keep working.
Icefil® feels immediately cool against your skin. In direct sunlight, the fabric helps deflect radiant heat from the sun, reducing the amount of heat it absorbs. As moisture builds, its cooling technology activates to help draw additional heat away. The result: skin temperature up to 5°F lower.
Immediate comfort
Feels cool to the touch - no perspiration required.
In the sun
Deflects radiant heat while moisture activates cooling.
HOW ICEFIL® WORKS
Cooling performance in three simple steps.
The science is sophisticated. The experience is refreshingly simple.
Deflects radiant heat
The fabric helps deflect radiant heat from the sun, reducing the amount of heat it absorbs.
Moisture activates cooling
As you perspire, Icefil® cooling technology activates to help draw heat away from the skin.
Wicks and dries quickly
Moisture disperses across the fabric so it can dry faster, helping skin stay cooler and drier.
COOLER BY DESIGN. PROVEN BY SCIENCE.
5°F
Lower skin temperature. More comfortable time outside.
Icefil® is engineered to help lower the temperature of the skin beneath the fabric by up to 5°F.
*Refers to skin temperature, not body temperature. Individual results may vary based on conditions and activity.

ICEFIL® FAQ
Your cooling questions, answered.
Everything customers need to know about IBKÜL's signature cooling technology.
What is Icefil®? +
Icefil® is IBKÜL's signature performance fabric, combining UPF 50+ sun protection with cooling comfort. It is cool to the touch and engineered to help lower skin temperature by up to 5°F while offering lightweight, moisture-wicking, quick-drying performance.
How does Icefil® cooling technology work? +
Icefil® helps manage heat in multiple ways. The fabric helps deflect radiant heat from the sun, reducing the amount of heat it absorbs. As you perspire, moisture activates additional cooling, while moisture-wicking and quick-drying performance help keep your skin cooler, drier and more comfortable.
Is Icefil® cool to the touch? +
Yes. Icefil® feels cool from the moment it touches your skin. It then goes a step further: as you perspire, moisture activates its cooling technology, helping lower skin temperature by up to 5°F.
How much can Icefil® lower skin temperature? +
Icefil® is engineered to help lower skin temperature by up to 5°F. This refers specifically to skin temperature—not body temperature. Results may vary depending on activity and conditions.
Does Icefil® provide UPF 50+ sun protection? +
Yes. Icefil® apparel provides UPF 50+ sun protection, helping block at least 98% of UVA and UVB rays. This protection is built into every Icefil® silhouette, from sleeveless and short-sleeve styles to long-sleeve tops, dresses, skorts and polos.
How is Icefil® different from ordinary UPF or moisture-wicking fabric? +
Ordinary UPF fabric helps protect skin from ultraviolet rays, while moisture-wicking fabric moves perspiration away from the body. Icefil® combines UPF 50+ sun protection and moisture management with cool-to-the-touch comfort and moisture-activated cooling engineered to help lower skin temperature by up to 5°F.
