About Us
GET THE FOG OUT!
You plan the trip, haul the gear, and drop in, only to spend the dive staring at a foggy lens. We started Fog-X to fix that for good. The world is worth seeing clearly.
Our Story
Fog-X started in the pool. Karl Hamouche was coaching competitive swimmers and watched fogged-up goggles get in the way of their two-hour practices again and again. Then he noticed something: new goggles come with a protective film stuck to the outside of the lens. What if a film on the inside could stop fog for good?
That idea, along with what Karl calls a deep-seated hatred for fog, became Fog-X, founded on November 21, 2019. Our anti-fog film first went to work in swim goggles in 2021. Divers and snorkelers kept asking for it, so we brought it to the dive world, with Karl's partner, cave and rebreather diver Brent Kiomall, alongside.
We first exhibited at DEMA Show in 2024. Today Fog-X comes in eight mask shapes, a swim goggle design, and a DIY film you can cut to fit just about anything. Fog-X has the full blessing of diving legend Dan Orr, and with dealers all over the world, we're expanding fast.
Meet the Founders
Karl Hamouche
Karl grew up in competitive swimming and went on to coach age-group and junior college swimmers. He graduated from the University of Iowa medical school and works as a radiologist in Ames, Iowa.
He's also the founder of Swim Smart, co-inventor of many of its products, and author of The Biology of Swimming and the Swimmer/Coach Starter Guide. If something gets between an athlete and the water, Karl wants to build the fix. He's a certified diver himself, and his favorite place to dive is the spring waters of central Florida. At home, he's a husband and father.
Brent Kiomall
Brent is an explorer at heart. He served as an infantryman in the U.S. Army, earned an engineering degree, led major energy projects, and started his own company. Then, in 2018, he found scuba diving.
Today he's a certified cave and rebreather diver who documents remote underwater environments through Brent Dives. He's also a co-founder of Divers Atlas. When your mask is your window into a cave, fog isn't a minor annoyance, and Brent makes sure Fog-X is up to the job. His favorite role, though, is husband and dad at home.
Why Fog-X?
Apply once. Dive for over a year.
Put it in like a phone screen protector. After that, all it needs is a drop of water before each dive to hydrate the film.
No spit, no soap, no burning
No more scrubbing with toothpaste or burning new masks (which can weaken the glass). Fog-X goes straight into a new mask without any prep.
Hydrophilic, not just "anti-fog"
Fog forms as tiny beads of water. Our film flattens that moisture into a clear, even layer, so you look straight through it. It also adds an anti-scratch layer to your lens.
Fits your mask
Eight mask designs, a swim goggle version, and a DIY film you can trim to size. Works with prescription lenses too.
Clean removal
A residue-free silicone adhesive holds it in place and leaves nothing sticky behind if you ever take it out.
Made by people who get wet
Started by a swim coach, tested by a cave diver, and built for everyone from first-time snorkelers to tech divers.
"As full-time divers, we've struggled with foggy masks more times than we can count. Fog X has genuinely been a game-changer. It works on every mask we've tried, from high-end freediving masks to cheap plastic ones, and keeps them completely fog-free. No soap, no spit, no defog needed."OceanGalz
