Easy Equalization
The IST Pro Ear Series features four incredible designs, each offering pressure equalization technology through a tube and seal system that’s unique to IST. Simply exhale into the mask and your ears immediately clear. The watertight cups not only help with regulating pressure, they also keep your ears warm and help prevent ear aches and infection.
Incredible Performance
The dual-lens design provides a crystal clear view while the tempered glass material maintains solid durability. Adjustable straps help you get the perfect fit and a clean seal so there’s no leakage, and a wide head strap distributes pressure to a large surface area so there’s no squeezing, pinching or discomfort.
Optical Choices
To make sure you get the best view possible, optical lenses are available from +1.0 to +4.0 in +0.5 increments and -1.0 to -8.0 in -0.5 increments. For a personalized prescription, the lenses are available for separate purchase and can be easily removed and replaced. Mix and match lenses to fit your optical needs.
