Rated 5 out of 5 by from Plans involve snow travel ? Buy these! I picked these up in preparation for some summer volcano climbing and I am psyched! They fit great, block out light in all those hard to protect areas like sides of the glasses, underneath the frame, and wont break the bank! You put them on and forget that they are there as they are very light and comfortable on the face. I love Julbo as they are a core mountain brand and they have hit the nail on the head yet again with the new Tamang.
