Great product

  • Familiarity:I've used it once or twice and have initial impressions

Great feel and warmth,just the wrong size (XL). Will exchange for L.

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?

Greetings - would go with a Large - as your inseam will most likely need the extra length ;)

nothing fancy but get the job done

  • Familiarity:I've put it through the wringer

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

Sizing question.

    I am 6'2" 210 lbs. any suggestions on size? Thanks.

    I'm 6'0" and the Large fits well. It goes to mid-calf. I guess I have normal sized legs and they are not too tight or loose.

    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.

      Medium should fit you spot on :)

      I'm the same size and mediums are just right.

      Excellent and great value

        These are really great knee warmers. Good fit and looks, very comfortable. At this price, they're a steal. I highly recommend these.

        fall riding

        Fun video, but not specifically useful for evaluating these knee warmers.

        my husband had knee surgery and the cold...

        my husband had knee surgery and the cold really gets to his knees. Will these help or are they just for bile riders

        They should work for anyone that needs to keep their Knees warm. He may have problems with them falling down because of no Lycra short holding them up.

        Toasty

          These are perfect for cold weather rides. I don't own a pair of full length bibs, but these are warm enough for rides between 40 - 50 degree f.
