VSN.Shield size information
Individuality rules. For the perfect fit of your sports glasses, it is important to order the correct VSN.Shield size. All VSN.Shields except the triathlon version VSN.KONA are available in small and MAX.
The MAX variants are a total of 4mm higher and cover a larger facial area. This means that they are suitable for larger heads or for wearers who generally prefer larger shield. The small versions of all shields are suitable for more delicate face shapes, whereby the width of both shields is always the same. The choice of shield size depends largely on your own feelings.
The rule of thumb: Around 95% of men prefer large shield variants, and this is also significantly more than half for women.
VSN.Kona
These shields are specially designed for triathlon, racing bikes, speedskating and similar sports. The very low posture on the racing or triathlon bike requires an unrestricted view to the front. This is guaranteed by the extra large panoramic windscreen with extensive wind protection. Additional side ventilation slits ensure increased ventilation even in high heat.
All SIOLS VSN.Shields are 100% UVA & UVB protection 400, distortion-free prismatic balanced.

Air Circulation Management: From strong ventilation (VSN.Shield Running with 10-point ventilation) for very intensive sports activities, to protection against drafts and turbulence (VSN.Shield Biking with 6-point ventilation) for fast sports, to temperature compensation of up to 80 ° in winter: all system panes can be flexibly exchanged and used.
Retina Shield: The design of every single lens in our range is the result of years of development work and thousands of test kilometers. Together with aerodynamics engineers, we developed our innovative ventilation technology for sports glasses in the wind tunnel. The result is a protected technology that we successfully use in all of our sports glasses: Retina Shield. It is the sum of all quality features of the SIOLS system lenses, which guarantee perfect vision and the best protection without compromise. An efficient and performance-oriented sports lens is characterized by its aerodynamic properties, ventilation and tinting. The lens is the "filter" between the environment and the eye and has two essential tasks. On the one hand to protect the eye from mechanical influences such as dust, on the other hand to support "seeing" as such through intensifying contrasts. Both components in combination with the best possible optical glazing result in the perfect sports glasses lens: the SIOLS VSN.Shield.
