Breathable Summer Mask with Thin and Filtering Fabric, Moisture-Wicking Technology
If you’re on the hunt for a breathable summer mask, the F1s is a hardy choice. It cools, moisture-wicks, filters, and protects from UV rays and bugs. It is great for cyclists, runners, gym goers, and others outdoor athletes who love a bit of training fun in the sun.
Cool, Moisture-Wicking Fabric
The F1s was created for the athlete training in the heat. It is made with moisture-repellent fabric technology that draws moisture on the skin to the surface and allows it to quickly evaporate, which creates a cool, comfortably dry feeling.
MICRONET™ Filtering Fabric Technology
A key feature of the F-Series, NAROO’s exclusive MICRONET™ filtering fabric blocks 99% of ultrafine dust particles, pollen and other harmful particulates as small as 1.7μm (40 times smaller than a human hair). Adjust the nose clip to fit snugly against your nose, which enhances filtering ability and reduces the fogging effect on any goggles or glasses.
Reusable and Washable
Even after 100 washes, the mask 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.
Multifunctional and Reversible
Because we know that athletes tackle all sorts of environments, we created the F1s 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 elastic ear loops can be looped around the ear to prevent slippage or tucked in so the fabric can protect your ears from sunburns. One side is equipped with MICRONET™ that filters 99% of particles. The reverse side sports SPAN MESH 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 the 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 F1s has been tested by accredited institutions in Japan and Korea, and has been approved by Allergy UK.

I love it.
I use it while jogging and it’s very breathable.
Most of the masks are not good during exercise when your sweat forms a film making it barely breathable. Fortunately, it doesn’t happen to F1S.
I also tried wrapping the mask around my PM2.5 meter and I got a significant reduction in PM2.5 reading. It’s not a scientific measurement but it shows that it’s good enough for me.

Great item for allergics like me. I had no idea how to survive at summer, because I work on nature.
Thanks!

This mask is perfect for the times you perhaps wouldn’t wear one. It’s light, airy, and very comfortable! Not the mask I use most but i wouldn’t want to be without it.
