Do these have any issue when worn with a helmet?
I've worn the Fishbowls with the following helmets: Smith Maze, ProTec B2, Pro-Tec Vigilante and the RED Hi-Fi and haven't had any fit issues. I tested the Fishbowl with the strap on the outside of the helmet and it fit great.
My personal preference is to wear it it with a thin beanie, under the helmet (the helmet feels more natural to me this way.) I have a thin, tall face and a larger nose and the Fishbowl fits me just fine. I can't guarantee the Fishbowl (or any goggle) will fit perfectly with every face and helmet combo, but I'll be riding it this year with the Pro-Tec B2 helmet.
Hope this helps.
I've got a Giro Seam and they fit perfectly.
