I have always been partial to brown because of the green and brown light enhancement of trees and trails. However, i have recently taken to Polarchromic lenses from Julbo for cycling, ice and rock climbing and Smith for hiking and casual. The sunglasses i have now are two pairs; Julbo Reflex and Smith Hideout.
Julbo Reflex goes from 41% VLT to 12% VLT
Smith Hideout (Ignitor Mirror) goes from about 35% VLT to 18% VLT
I highly recommend both of these and of course the Smith’s are Teclite glass lenses which are the bomb!!!
