Well, they're about as thick as my new Hellraisers (Dainese), or my old Frank Thomas gloves. For a moto / winter glove they're pretty medium. They're not as bulbous or thick as my Grandoe Goretex two-piece / insert, and those are the toastiest thing in the world.......just kind of clumsy on the controls......I just like really toasty fingers myself.....those ones above, so far, are pretty toasty...I'll keep ya posted....How thick are they ? I want a warm thin glove, if there is such a thing ?Well you COULD use a ski glove, I know, I know...my bad. I just purchased a pair of Dainese Guanto Ziong D-Dry off ebay from a place in Colorado. $50, or so, and they seem to be the nicest piece of cold-weather glove I've purchased in a long time. Windproof, waterproof, and much warmer than any leather / insulated I've had thus far. I little mushy in the fingers, but more than enough grab for everything I do.......I'll keep ya posted......
