The worst part of cold-weather riding isn’t the harsh cold in your throat or the inevitable snots, it’s frozen, aching knees. Castelli designed the Thermoflex Classic knee warmer to keep your knees comfortable without interfering with your pedaling. The inside of the knee warmer is a soft fleece, so it feels good next to your skin.

I bought these a year ago. they have a simple design but the brushed fleece is comfortable and adds to warmth. I use them in temps from the mid-40s to 60. 5'8" 145lbs and purchased size medium

Oh so cozy

    Love these for those crisp morning rides where leg warmers would just be too much, but flying bare would be too uncomfortably chilly. These are made of a quality and cozy material, and come at a surprisingly low price for Castelli. I am 5'10 160lbs and found the medium to fit perfectly.

    I'm 6'2 168lb with pretty dang skinny legs. What size do you suggest? I'm guessing medium but I typically size up in castelli... Thoughts?

    What size do I need? I am 5'10 150 ibs
