I used to never wear my helmet because my goggles were not comfortable to wear with it. I tried on some friends Phenoms and decided to buy some for myself. I started wearing my helmet again because the Phenoms were so comfortable and never fogged up. Two days after I bought the goggles, I ran into a tree and cracked my helmet completely in half. The goggles broke in the collision with the tree, but Smith was awesome and replaced them for me at no cost! These are all around great goggles to wear with or without a helmet, and Smith is an awesome company with great customer service!
