Exclusive MICRONET™ Filtering Fabric Technology
MICRONET™ filter fabric blocks 99% of ultrafine dust particles and pollen with sizes starting from 1.7μm (40x smaller than a human hair), including fine pollution particles that average 2.5μm in size
Reusable and Washable
Even after 100 washes, the cool face shield continues to block 99% of dust particles, allowing it to be reused repeatedly without damaging its dust-blocking performance, perfect for an athlete on the road.
Quick-drying
NAROO’s nylon blend fabric wicks moisture away from your skin, which allows it to spread out and dry quickly.
Multifunctional and Reversible
Because we know that athletes tackle all sorts of environments, we created the cool face shield F5s to join you on your journey. We were one of the first to develop this 2-in-1 reversible and multifunctional tube-like mask that makes the best use of the entire accessory. Even the ear loops can be looped around the ear to prevent slippage. One side is equipped with MICRONET™ that filters 99% of dust particles. The reverse side sports breathing holes to protect you from insects and harmful UV rays.
Breathable and Comfortable
A sports mask should be the most breathable mask. At NAROO, our designs achieve breathability in part thanks to our special MICRONET™ filtering technology. The form-fitting, high-quality, soft fabric offers the stretch and comfort you need while also taking the shape of your face so that the mask creates a safe, snug seal. Because the knit and fabric are what create the filter, we balanced the filtering and breathability aspects to give you the best of both.
Tested, Certified, Safe
NAROO constantly strives to be sure that our masks are up to current testing and safety standards because we value how hard athletes train and work for their goals. The cool face shield F5s has been tested by accredited institutions in Japan and Korea, and has been approved by Allergy UK.
