Frame:  Polished Black
Lens:  Black Iridium Polarized
Simple, classy, sleek.  They describe the enduro.  From first try I knew I had to have a pair of these.  The first batch is tame on the color combinations but I can see them going crazy with these like the Holbrook.  If you have many Holbrooks like me and want something smiliar these are they way to go.

Frame: Grey Ink/Black Ink
Lens: Black Iridium/Chrome Iridium Polarized
I usually prefer squared frames but I decided to try the enduro and really like the look.  They fit really well and are extremely light.  They have a classier look, almost like some designer frames from other brands.  There's also a lot of variety so you can get more plain frame/lens combo or something more flashy if you prefer.
