Question: do they fog easily?
Document: I simply trust the performance provided by Oakley. Great skiing goggles and they don't fog up easily. I love it!
This goggles fit well. Did not have any problem with lens fogging up. Also the lens are easily interchangeable. I would recommend these.
Fogs up easily but I perspire alot. Wide visual field. Comfortable. Strap doesn't slip-off or ride-up during use. I would purchase again.
I purchased these believing that the Oakley brand name would deliver, but I was disappointed. The Clear lens doesn't seem to have any coating to reduce glare, and they got easily fogged up. I will be looking to purchase a replacement lens  for these :(
Sturdy, well ventilated. They don't fog up, ever. I have no complaints with these goggles, and would buy them again in a heartbeat.
These goggles rarely fog up when riding my ATV, good stretch around the helmet. Pretty comfortable on the face overall.
These fit the bill. I have a problem though If I wear a neck gator they fog up and become completely useless to me.
product arrived fast used them and to my surprise they did not fog up at all during the ride n a hot sweaty day. good price fit perfect
Totally a good fit, easy to exchange lens during a ride assessment, and or on the trail. breath nicely and don't fog up at all, comfortable on the face and nose.
the goggles work perfect in the snow no fog up visibility was great and the delivery was fast and yes they are small but I have a small face so it worked out fine
Answer: yes
