What do you guys wear in the winter ?

Clothes LOL.  In all seriousness it depends on how cold it is and what I plan to be doing out there.  I have found over the years that it doesnt take super special clothing.  If you can keep the wind and the water out that is 99% of the battle.

well if you are riding at any speed I would recommend a leather coat, there's a reason bikers wear them. They make a HUGE difference. Other than that just bundle up. I mean if you plan to do a lot of serious cold weather riding go look at snowmobile stuff, heated clothes and stuff and wire it in to the machine.

I would highly recommend  Gordon Gerbing heated clothing.  He was the original maker of great heated riding gear for just about any sport!  They have jacket liners, gloves, pants, and even electric socks. Reasonably inexpensive, durable and an all around great product.  Plug it in, and then ride like the wind!

Thanks, I'll have a look around

If it's cold enough, sometimes just a good pair of winter coveralls does the trick for me. Otherwise a few layers and my riding coat is all it takes.

I have used a few layers of clothes and a good rain suit works well also. Keeps the wind and water out.

Carhartts!

Snowmobile gear is best. Made just for what you want to do.

I just found a pair of fleece lined camo Wrangler cargo pants at a local store for only $17. They are similar to these -> https://www.amazon.com/Wrangler-Authentics-Mens-Fleece-Lined-Cargo/dp/B00XKXI3WG

I also picked up a Wolverine Finley duck jacket for $30 from Super Shoes on a sale after Black Friday. $30 for this heavy jacket, very similar to a Carhartt, was a steal !

Between these two, I have plenty of lining and material, and I only paid $47 for both, less than a Carhartt jacket by a good bit. It pays to shop around.
