I have the Realm with the Blue Solex lens. Performs great in all conditions; wet, dry, cold, warm. Rode many nights with these as well, and a greater VLT lens would help but really no problems. I wear these with a helmet and neck gaiter with no fogging issues. Have borrowed a friends Smith I/O and they seem to fog all the time with a helmet, even though it's a Smith helmet.
Anyhow, Anon makes great stuff.
