I've used various face coverings, both light weight and heavier fleece.
The biggest challenge is moisture management whenever you cover your mouth and nose.
Your breath will coat the inside of your mask and soak it eventually. That breath has to escape somewhere, so it will fog up your goggles as it escapes around your cheeks.
And, you breathe a lot more when you're cycling than you do when fishing or hunting (what most of these products are designed for). I guess that's my big critique of the SA co website; if you wear their mask with goggles like they show while cycling, your goggles will be completely fogged within minutes.
Some masks have ventilation holes or mesh to help mitigate the moisture build-up, but they still get soggy after >30 mins.
My solution:
snowboard goggles +
nose/cheek mask +
lycra, fleece, or wool neckscarf/tube/buff pulled up to my lips
Basically, what this guy is doing.

It leaves a gap for the breath to escape while shielding your cheeks and chin.
That company,
OuterU, sells a FaceGlove that seems well-designed for the task.
Currently, I use a smaller, moustache-like piece that velcros to the goggle itself. Mine was called the "Original Pinch" and I bought it from KayaSport in Canada. Their site is no longer active, but this product (
Wizard Warmer) seems pretty much the same thing.
But I may buy an OuterU Faceglove for this winter, it seems like a good solution.
