The soft adjustable nosepad offers an exceptional fit for any shape of face. This system also allows to adjust the glasses’ height and their distance from the face to prevent misting. Soft temple tips ensure a perfect grip.
ImpactX® lenses are photochromic. This means they get dark from low to high light transmission within few seconds and reaching a custom color from an initial clear state. They enhance contrast, improve visual acuity and depth perception. ImpactX® lenses are 16% lighter than CR-39 and 10% lighter than polycarbonate; they have lower internal stress and chromatic dispersion than polycarbonate, resulting in sharper images, higher definition, reduces “rainbowing”, and more visual comfort.
Rilsan Clear® is a high performance sustainable and bio-based polymer of 100% renewable origin, developed by Arkema. Rilsan Clear®’s key properties are lightness, chemical and fatigue resistance, flexibility and easy processability which make this material extremely durable, shock and weather resistant and perfectly suitable for sports use.
I got 3 of the spinair 58 purple, blue and red. I bought the glasses because of the adjustable nose piece. Now I'm buying the Demi brown.
My Propusle RX prescription glasses with ImpactX Photochromic 2 Red are my all-time favourites. For everything from XCO racing to Gravel night rides these lenses perform under a wide range of conditions. I love them so much I'm planning to buy a 2nd pair.
Great helmet - combo of perfect fit, light weight - really nice for training. Easy to adjust / fits according to sizing.
Nice plus - great helmet for racing triathlon in really hot conditions - very breathable for racing yet aero.
Would / did recommend to many friends who also like it as well.
