I recently purchased my first helmet. A 2012 Giro G10 (matte grey) (not MX). It fits fine and is very comfortable. I also purchased a pair of Scott "Strike" goggles which I also like very much. I used them both for the first time this weekend. Separately, I like them both. Together, I am very frustrated. With the helmet on and the goggle are over my eyes, everything is great. Great vision, no air leaks, fogging or other issues. When I have them up on the helmet "brow" (inside the lodge, waiting in line, in the shade etc., which I do often) they slide up and off the back. There is no "middle ground" for them. If they are low enough on the helmet "brow" to NOT snap back, they are solidly obscuring my field of vision. If they are high enough to be out of my field of vision, they slide off the back. The helmet is too smooth and slippery and the cotton goggle strap only adds to this.
