Cycling during the cool weather months can be a big guessing game. Starting out, you're freezing! But once you get into your groove, you're on fire. How do you correct this imbalance? To make autumn and spring rides more manageable, the creative minds at Castelli put their heads together as to how to make you stay warm even in chilly temperatures, while also keeping cool after your body heat builds. After working with the professional Ineos cycling team, they developed the Pro Seamless Knee Warmer to enhance your natural body heat without any unnecessary bulk.
Constructed using a unique blend of polyester, nylon, and Lycra® elastane, this lightweight layer provides exceptional warmth and moisture management. With a seamless design, these leg warmers are comfortable to wear as long as you need to, while also stretchy enough to provide a great fit on most body types. Plus, they are super compact, so you can take them off and fold them up to stash in your rear jersey pocket whenever they aren't needed.
These warmers are the ideal choice for early morning or late-night rides in cool to mildly warm weather. So, no more struggling with intermediate temperatures or regretting the decision to wear tights. With the Castelli Pro Seamless Leg Warmer, you can ride like a pro with the gear that will get you through it all.

Great light weight for days when the temperature is just below 60*F. Unfortunately the top seam unraveled after one or two rides/washes (gentle cycle, cold water, hang dry). After every use, I needed to cut away coils of loose threads with the compression suffering each time. Probably got no more than a dozen or so rides with these before trashing.
on my second pair of these knee warmers (I also have and recommend the arm warmers) these are my go to warmers for temps around 50 degrees and up. they do require delicate care putting on and taking off as the stitches can get easily damaged from pulling too hard. otherwise great product.
Castelli nailed it with these seamless leg, knee and arm warmers. They must use a very high loft insulating fiber to knit them. They are super soft, stretchy and very warm for their weight and thickness. Although they look small when you get them, they stretch a lot. And thus far have not lost their shape or rolled down.
I expected these to have a fleece lining. Nope. Super thin but they were surprisingly adequate on a 45 day. Alright, okay! Then got a run in them. Once I took them on a longer ride I noticed they slipped down. Overall disappointment. But they will now be my go-to under tights on super cold days.
These knee warmers are comfortable, easy to get on/off, and plenty warm for me, but they won't stay up. If you get them, plan on stopping every hour or so to pull them back up into your shorts. I have since bought a pair of the Pearl Izumi Elite Thermal Knee Warmers, and they are much better. I am sorry I don't have two pairs of those.
