used mine on Monday....were ok as a nice breeze was blowing but also warm for December though, very comfy and a nice seal, had the fast helmet on and although I wouldn't say fogged up like a guy next to me in other googles....the moisture was a pain at times, for the last 30mins of my day I used my ESS ones but again they got wet!....
* note these were all untreated, straight out of the bag as have yet to get any application products to try (using the famous search function to locate the topic, I know one was cat cr@p....!), also I need to remove the foam from them which should free up the vents more.....not sure the helmet helped either?..................ooooh and maybe if I was trimmer like this time a few years ago.,....haha
