Protect the knees to a certain degree.

The Assos Knee Warmer is a versatile piece of kit for your spring and fall rides. It can help extend the range of your shorts and allow for some warmth as you embark on a chilly ride with the warmers on, or bring them with if the weather is unpredictable or your fall 'cross training or early spring intervals have you running short on daylight. Assos crafts them using RX light which is the same textiles found on some of its winter jackets offering maximum insulation and protection. RX light is very elastic allowing for an excellent fit and it's also extremely breathable so your pistons are firing at their optimum operating temperature.  To ensure a proper fit, these Knee Warmers get an anatomical cut to fit your left and right legs while in the riding position. Each warmer is labeled so you'll know which one belongs or what knee. Finally, Assos employs a DWR treatment that repels water helping you and your knees stay happy during an errant spring shower.

  • Knee warmers for cooler spring and fall rides
  • RX light fabric breathes and wicks moisture
  • Anatomic right/left design for a proper fit
  • DWR treatment resists wheel spray and spring showers

For best results, take measurements over your underwear.
Measure around the widest part of your chest.
Bend to the side and measure around the place where your waist bends, keeping the tape a bit loose.

It's hot up on the ridge, with the computer reading around 90-95 degrees; you wear highly evaporative, thin summer race wear to stay cool. Then you descend to the coast and into the marine layer... fog wraps you like a cold blanket, the temps drop fast and it's soon in the low 60s. You're frozen like an icicle. But you knew this would happen and up on the ridge before heading downhill put on your wind jacket and knee warmers, while taking off your sweat band to avoid that ice cream headache on the way down. What a difference it makes. These knee warmers in size I roll up really, really small - smaller than the Other Brand I had before, that were twice as short and no better or worse in terms of insulation. They're long enough cover a significant portion of the upper leg as well, forming a second layer under the bib shorts. They come on and come off easy over shoes. There's no bunching to speak of... they just do the job. It's one of those things where Just Works is in itself a form of perfection. I don't know what else to say of them. They fit nicely alongside a jacket in a jersey pocket.

I have used a couple of times. It keeps in my legs without holding too much tight, extremely plushy internal fabric and makes you feel warm enough for temperatures about 5C (I live in Sao Paulo, Brazil). Definitely a good purchase!
