I had thoughts of converting my hockey helmet visor to bike use (to keep my eyeballs from freezing on those really cold days), when I came across this "windscreen visor" in the Louis Garneau ]2002 Summer catalogue (under "helmets"). I could have used this on the weekend, MTBing through the woods, caught a few cheek scratches from branches.

Anybody tried anythng like this?

(sorry about the awkward link, I tried to attach the picture, but it wouldn't work)

On really really cold sub-zero temperature days, I use double paned ski goggles. Those kind of days, I usually need a full face mask too because anything exposed gets frostbite.

A windshield might work, but I noticed on really cold days, my breath freezes quickly to almost any eyewear. FOr this reason, I use the double-paned ski goggles. A simple shield might frost up and impair your vision.

I saw one like that in Performance bike's catalogue. I've thought of getting it too.

I have no experience with it but I read on some newsgroup that the Velcro does not hold it al the time.

previous thread in winter biking entitled, helmet "shield", has more responses on this topic.

The cheapskate version is just to use safety goggles, like they sell in HW stores. Don't know how they would work in extreme cold as described above.

Functional, but you will forfeit many style points.

I use the cheapskate solution. I use $5 laboratory safety goggles. Extra plastic lenses are like $3. They're not tight all the way around so they vent well. But they are more than enough to keep the cold air and snow off of my eyes. I've been very happy with this solution in cold air, snow, or freezing rain.

But you won't see them on the cover of any bike magazines...

I use the Garneau windscreen visor. No problems with fogging, but did have problems with the velcro coming loose. So I attached it permanently to my helmet with two shallow screws. It positions far enough from your face so you can get wrap-around sunglasses under it with no problem. Cleans easily with Windex while still on the helmet. This visor has done a good job protecting me from huge bugs that hit me head on in the summer.
