I love the options for lenses, the clarity and field of view. The only downside is that the bridge of the nose is a little to tight which leads to some minor wind leakage around my nose (not an issue with the IO X) That being said I have two pairs of the IO. Also Smith has an excellent warrantee and fixed an old pair at no cost for shipping or anything.
I bought them for spring riding but they were a little warmer than I expected. Super comfortable, lightweight spring glove feel but keeps my hands warm down to about 15/20 degrees. Also, they really do keep your hands dry.
This thing is crazy stiff but the flat camber keeps it playful. Great for big jumps, big pipes and going really fast in general. Floats well in the deep and cuts crud like a Hanzo sword. Only downsides are the price and the top sheet is way slick so your one foot tricks may require a stomp pad.
Lightweight and agile especially considering the width. Great float in the fresh and descent stability at speed for bigger jumps. Moderate flex with the flat to rocker makes for a playful board that shreds the entire mountain.
