Castelli's Thermoflex 2 Kneewarmers provide luxurious fleecy warmth on dry and chilly bike rides in spring, fall and winter.
If you don't need the extra wet weather protection of Castelli's Nano Flex fabric, you'll find that the Thermoflex warmers outpace traditional warmers with a combination of the softest, most comfortable fabrics and the brand's careful attention to construction details.
The single-piece design means the Thermoflex 2 Kneewarmers won't rub or scratch while the dual-sided silicone grippers prevent slippage and keep them locked in place.

I use these when the temps are low early in the morning but warm up as the morning carries on. They are great to take the edge off over knees being exposed. Light enough to pop them off on longer rides and shove them into my pocket. Would recommend.
I own other knee warmers and I use them a lot including other castelli's. I know the tricks of keeping them in place. After two sets of these in two different sizes
(after conversations with you) these just will not stay up- I suspect it's the lining as I don't have this problem with other brands or sizing.
I've completed only one day with these and I'm glad I got them. It was a few degrees under Castelli's recommended 54 degree minimum and my legs felt fine (there wasn't much wind though). They seem a bit warmer than other pairs I have. They gripped pretty well, although I did have to pull them up once during the 3-mile ride. The soft material and flat seams make them very comfy.
