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.
