Momma Don't Take My Photochrome Away
I will start out by saying that I have a fairly large dome. These do have a fairly large frame, but with the adjustable temples on these I don't see why they won't work for anyone with an averagish sized face.
I bought these primarily to wear while bootpacking/skinning in the Tetons and for this they work awesome, and thanks to the photochrome they even work for driving when it's sunny out. I haven't noticed any light leakage as mentioned in another review.
The first day I had them I did do a hike with the side shields on, then my second hike without them and it definitely made a difference. The wind was noticeable with the side shields on, by no means intrusive, but was nigh unbearable without them.
In summary, these are a great pair of mountaineering shades, I can't wait to try them out on the river and peakbagging this summer.
