I tried the aviators did not work well with my klim.
I called and talked with them they sent me a pr of the black ops in trade they work great .
great customer service I thought.
aviators fit perfect in my cat helmet, got a pair of pro air snows with ls lense too for trial - night riding. the pro air snows will be warmer I think, but the look and function of the aviators is undeniable.
best pair i ever got used all brands and makes till i found them still have about 6 pares of other ones but still only were the Aviators i have a klim f4 helmet and they fit fine just loosen the goggle straps as loose as possible
