Are these googles helemt compatidible with the smith variant brim helmet? I love the design of the gogs but I want to make sure before I purchase them that they will fit correctly. Also, do these goggles fog up a lot? I do a lot of backcountry skiing and I have to hike to get up to the trail and will they fog up if I have them on my face while I sweat and breath? because I have owned a pair of goggles before that did this and I really didnt like them, they were a pair of smiths and I am hoping the oakley splices wont do this.
