These are the most comfortable, warm, and durable warmers there are. Easy to remove mid-ride if you get too warm. They roll up and tuck in your jersey with ease. Well marked with R and L labels too.
Best knee warmers I've had. Extremely high quality, comfortable, and propel rainmoisture well. The knee warmers I'd had previously did not hold in place throughout a long ride, and these have always stayed secure. If you're contemplating buying these, you will not be disappointed.
Recently wore on a chilly 35 degree morning and worked well.
These knee warmers are great for days when the temps are in the 20-40 degree range for those that dont like the full leg warmers.
These are thicker than summer weight lycra that you see on bib shorts, etc., and seem thicker than previous years' models. YMMV but I use them down to about 45F. The limiting factors are the thickness of the accompanying shorts and socks, not this knee warmer.
