The M5 runs a flat-toric lens: more peripheral vision than a cylindrical lens in a cleaner, lower frame than the M4. Magna-Tech magnets handle lens swaps and an MFI face mask comes in the box.
It hits the middle ground a lot of riders want: wide view, quick lens changes, and a frame that sits right with most helmets. Two lenses in the box means you are covered sun or storm.
Riders who want a big field of view for scanning lines in Horseshoe Bowl and picking through the trees on Peak 10.
