How to pick the right fit & lens

  1. Fit: Medium suits most; if you have a narrow bridge or small face, try Small.
  2. VLT & tints: low VLT for sun; higher VLT (rose/yellow) for overcast/flat-light.
  3. Helmet check: test with your helmet—no gaps or blocked vents.
  4. Prescription glasses: check OTG compatibility if you wear eyeglasses.

Pros & cons

Pros

  • Ultra-fast lens swaps.
  • Excellent contrast and terrain reading.
  • Strong ventilation with less fogging.

Cons

  • Pricier than standard goggles.
  • Handle carefully to avoid scratching the lens.

Setup & use

  • Swapping lenses: keep hands clean and dry; rest the frame on a soft surface, gently release the magnets, then seat the new lens.
  • Ventilation: keep channels open (avoid stuffing a buff under the frame).
  • Helmet pairing: test strap position/angle to eliminate any “gaper gap”.

Care & storage

  • Air-dry naturally; avoid wiping the inner lens when wet (anti-fog coating is delicate).
  • Use the microfiber pouch; place lenses face-up on soft surfaces, not hard ones.
  • Keep away from heat sources (radiators, overnight in a cold trunk, etc.).

FAQ

Which lens works best on overcast days?

Choose a higher-VLT tint (e.g., rose/yellow ChromaPop™) to boost contrast in flat-light.

Are the magnets secure in a crash?

The magnets work with a mechanical catch; properly seated lenses stay secure during normal use.

Can I wear them over prescription glasses?

Check OTG compatibility with your frame. Alternatively, consider a prescription insert.
