You can still get silk balaclavas which I think work better for Tx changing weather than the others. I have one that is about 33 years old that I wouldn't trade for anything. It rolls up into a ball a little larger than a walnut, which is so small I've lost it tucked away in pockets several times.
 
Another thing I use a lot is a light, knitted neck gaiter. Most of the ones you see are a little too heavy and stiff and tend to get in the way. A neck gaiter tends to keep my upper chest and neck warm. With the gaiter and silk balaclava I can dress a lot lighter, often wearing just shorts, a wicking base t-shirt and a long-sleeved tshirt down to around freezing.

My most important piece of winter gear is my polar fleece balaclava, fits under my helmet and keeps my glasses from fogging down to about 40F, below 40 I have a foam baffle I stick on top of the chinbar that really keeps my lower face warm and my glasses clear. Those of you not wearing full face helmets may want to think about one for the winter, they're the BOMB in cold weather with a 'clava. And if it ever gets really cold you can put duct tape over the vents and get another inch or so insulation.
 
Also if it gets really cold I can tuck the tails of my 'clave under my jersey to keep me warm all the way to mid chest. And I second the wool jersey keeping you warm even when wet, combine one with a breathable windproof outer layer like Goretex (I used to use one of the cheaper imitations) and you also have a winner down to about 30F, lower with more layers.
