The Parallel frame wraps my face snugly leaving no gaps for air to sneak in.  I have a smaller face (apparently) as Smith "medium" glasses usually fit me well.

The frame measures 135mm from temple to temple hinge.

My first outing with these was in full sun on snow.  The brown polarized lenses are excellent.  Cuts glare and enhances contrast.

The Ignitor lenses are fantastic for overcast days or transitioning in and out of shaded tree cover to open areas.

A hard zippered case was included with mine.  This was not mentioned in the product description so it was a nice unexpected bonus.
