Clearflow Antifog Adapter
Ditch the Goggles. Keep the Antifog.
Clearflow connects your powered antifog unit to your tactical glasses - full field of view, low profile fit, one-motion quick detach. No tools, no tape, no goggles required.
The Problem
Your antifog works great. Your glasses have no way to connect.
Every powered antifog system on the market - ExFog, Novritsch, all of them - was designed for full-seal goggles. They use tubes that tuck into a rubber gasket. Tactical glasses don't have a gasket. They don't have a seal. They have nothing.
So players hack it. Zip ties through the frame. Tape around the arms. Tubes flopping loose against the lens. The result: eye irritation from uncontrolled airflow, pressure points from zip ties against skin, and kinked tubes that cut off airflow entirely.
The antifog unit still works. Your glasses just don't have a mounting point. That's what Clearflow fixes.

Why Clearflow
Built for glasses. Built for the field.
Model-Specific Fit and Gasket/RX Compatible
Not a universal clamp. Each adapter is designed to the exact geometry of your frame. No tools, no adhesives, no modifications. Most supported frames are confirmed compatible with aftermarket gaskets and RX inserts (See compatibility table for details).
Engineered Technology
Vents shaped to push air laterally across the lens - not into your eyes. When glasses are pressed tight against your face, uncontrolled airflow means dry, irritated eyes. Engineered vents direct air along the lens surface and keeps it there.
One-Motion Quick Detach
Pull the elbow out of the adapter and the tubes disconnect. Remove your helmet without removing your eye protection. Clean your lenses without unpacking your whole setup.
System Agnostic
Every kit includes elbows for ExFog (6mm) and Novritsch (9.5mm) tubing. Pick your frame. Use whatever antifog unit you already own.
How It Works
Three steps. No tools.

Clip it on
Attach the adapter near the lens via slide or clip fit - no tools, no tape, no modifications. The precision fit holds it in place.

Connect your tube
Press the included elbow into the adapter port. The elbow rotates so you can route tubes up, down, or to the side. Works with ExFog and Novritsch out of the box.

Pull to detach
Pull the elbow out of the adapter in one motion. Tubes stay with the helmet. Glasses stay on. No fumbling, no tangling.

What's Included
Everything you need.
Nothing you don't.

- ExFog elbow set (6mm) Two 90-degree elbows for ExFog-style tubing
- Novritsch elbow set (9.5mm) Two 90-degree elbows for Novritsch-style tubing
Elbows rotate so you can route tubes up, down, or to the side - whatever works for your headgear setup. Tube not included. Need some? The BFly Routing Kit has everything you need.
Engineered Venting
Air that washes your lens. Not your eyes.
The vents inside Clearflow are shaped to compress airflow into a flat, directed stream. A guard on the eye-facing side deflects air away from your eyes entirely.
The result is a full wash of moving air that travels laterally across the lens surface - evaporating sweat condensation as it goes - without blasting into your eyes.
- Directed lateral airflow across full lens surface
- Opposing flows meet at the nose bridge, forcing excess air up or down
- Upward air moves out, downward air fights the dreaded "hot breath" fog that happens when wearing face protection

FAQ
Common questions
Will this work with my ExFog unit?
Yes. Every Clearflow kit includes 90-degree elbow connectors in both ExFog (6mm) and Novritsch (9.5mm) tube diameters. Select your frame model and use whichever antifog unit you already own.
Does it require any tools or modifications to my glasses?
No tools. No adhesives. No modifications. The adapter is designed to the exact geometry of your specific frame and presses into a secure fit on its own. Fully reversible - remove it anytime with no trace.
Will it stay on during a game?
Yes. The precision fit holds the adapter secure without adhesive. The elbow connector stays firmly seated in the adapter port during normal play and rotates to allow flexible tube routing.
What's in the kit?
One left and one right Clearflow adapter for your selected frame model. Two 90-degree elbow connectors for ExFog (6mm) tubing. Two 90-degree elbow connectors for Novritsch (9.5mm) tubing. Tube not included. Need some? The BFly Routing Kit has everything you need.
My frame isn't listed. Can I still use Clearflow?
Not yet - Clearflow is engineered specifically for each supported frame so a generic fit isn't possible. New frames are in development. Contact us with your frame model and we'll prioritize accordingly.
Is it compatible with gaskets and RX inserts?
Confirmed for ESS Crossbow, ESS Crossbow Suppressor, Oakley M Frame 2.0, Oakley M Frame 3.0, Bloc Tactical Predator, and Bloc Tactical Lynx. See th
Confirmed for all ESS Crossbow variants, all Oakley M Frame variants, and all Bloc Tactical variants. See the compatibility table above for full details.
How durable is a 3D printed part?
Clearflow is precision FDM printed from engineering-grade plastic designed for field conditions. Not flexible or rubbery. Made in the USA.
