help Smith I/O MAG FAQ
How does the Smith I/O MAG magnetic lens change system work?
The MAG system uses strategically placed magnets in the frame and lens to create a secure connection that allows tool-free lens swaps. Simply pull the lens away from the frame and the magnetic attachment releases, letting you snap in a new lens quickly even with gloves on.
What is ChromaPop lens technology and why does it matter?
ChromaPop uses proprietary lens filters that separate light into wavelengths the human eye perceives as blue, green, and red. This reduces color confusion and enhances natural clarity, making snow contours, ice patches, and terrain variations easier to identify in various lighting conditions.
Will the Smith I/O MAG fit with my existing ski helmet?
The I/O MAG features a medium-large profile with a wide 40mm strap and is designed to be helmet-compatible with most major brands. The AirEvac system integrates with Smith helmets specifically, though it works generally well with other helmets through standard strap routing.
How do I prevent fogging in the Smith I/O MAG goggles?
Ensure your goggles are completely dry before use, avoid storing them in damp conditions, and never wipe the inner lens aggressively. The dual lenses with anti-fog coating and proper ventilation work best when you maintain a slight gap for airflow and avoid covering vents.
Can I use the Smith I/O MAG if I wear prescription glasses?
Yes, the I/O MAG is OTG (over-the-glasses) compatible with a notched foam design that accommodates most prescription frames. For optimal comfort, choose glasses with smaller frames and thinner temples to ensure a proper seal and seal around your face.
