I have knee warmers and leg warmers that I transition to as it gets colder and then eventually my chamoisless tights. I wore the knee warmers underneath the tights the other night and it increased warmth considerably. Likewise the leg warmers could be worn at colder temperatures. These three articles of clothing provide for a lot of flexibility across a broad range of temperatures. The DeFeet Knee warmers are very inexpensive and most importantly, stay in place. Bellweather leg warmers are relatively inexpensive also.
