"Great mask! Light weight, no fog, and very easy to put switch out lens. When you get it though it's a clear see through lens, I got a blue ic for it and it looks amazing!

"Worth every penny!
I bought this for op Bad Blood 2014 and this worked amazingly. No defog spray used.

Never fogs even when you sweat IN the mask
Seems like a helmet can be worn on top, but i'm not too sure.
Glasses fit perfectly but need defog spray to not fog either.
Very comfortable all around
Easy to adjust

Looks a little awkward because of its small frame

"I wish I could add more stars to this product, the I4 is simply the best mask I have ever used. period.

zero fog.

great visibility, I can even use Iron Sights if I want.

Comfortable, this is for me personally I like the way it fits I do have to wear a bandana as I sweat more then the foam can absorb, and my big ass ears press up against the ear protectors to much. but with the bandana all these problems are taken off the table.


zero fogging
easy to swap lens
awesome visibility
fits under some helmets
Tons of Replacement lens available


Very low profile some longer chins will be exposed.
Ear covers can hurt those of us with larger ears
The price is high (but I assure you not a penny is wasted on this product)
Dye i4 Pro Airsoft Full Face Mask - Black / Thermal Lens
Dye i4 Pro Airsoft Full Face Mask - Black / Thermal Lens

The smallest profile, lightest, and best field of vision available. The Pro i4 is the apex of Dye’s long legacy of goggle engineering. The thermal lens leads the industry in optical clarity and provides a distortion and fog free field of vision regardless of weather. The i4 system also has a variety of lens options to match your lighting conditions.


Tiger Teeth Retention System: Tiger Teeth buckles allow you to adjust your Invision woven rubber strap for a custom fit. Tiger teeth are designed to bite down and secure the strap during rigorous competition.

Horizon Peripheral Vision: The i3 offers outstanding peripheral vision, providing more than most other goggle systems on the market today. This added vision makes movement easier to recognize, providing a distinct tactical advantage for users. The i3 includes our optically correct toroidal impact lens to protect your eyes. In addition the i3 goggle comes standard with HARDCOAT, a scratch resistant coating that protects both sides of the lens against scratches and minor abrasions. The included UV coating also provides exceptional protection from the sun's harmful rays.

Anti-fog Thermal Lens: The i3 Pro features an industry first compound radius lens with thermal technology, giving the player the ultimate vertical/ horizontal peripheral vision. Dye thermal lenses provide the benchmark for anti-fog performance. All Invision lenses provide perfect optical clarity and set the standard for visual performance.

Rapid Lens Change: The i4 has a revolutionary patent pending rapid lens change system, allowing lens changes in ten seconds or less. It is as simple as pushing on each interior tab arm and then sliding them forward, instantly freeing the i4 lens for replacement.

Anatomic Fit & Function: The anatomically correct i3 mask system offers the best in comfort for all facial contours.. The i3 is tested at twice the current impact ASTM and CE standards. Dye’s proprietary dual stage foam combines open and closed cell foam technology. Dual stage foam is specifically designed to “sheet” sweat and moisture away from your face, providing an undeniably resilient boundary between your eyes and perspiration.

Compression Formed Ears: Ear protection is critical, but it does not need to be bulky. The i3 system features a compression formed earpiece that is soft, flexible and extremely lightweight. Cool Max® material in the ear protection has also been added to increase moisture evaporation.

SCREAM Multi-directional Venting: Using patented technology the i3’s precise blade angling and proven venting configuration, heat and moisture dissipates quickly. Scream Multi-Directional Venting makes communication with teammates effortlessly by carrying your voice farther.

Size: One Size Fits Most, Adjustable
Color: Black
