Not too durable

  • Familiarity: I've put it through the wringer

These are comfortable and work well down to 45 degrees for me. Although functional, there are a few downsides. First is the rubber in the slip band at the top is not woven in so it will start coming off after a few washes. Second is the logo starts to come apart because it is not printed or sewn on. They will look pretty worn pretty fast. Do not buy for high usage cycling.

Would these work for women? I'm 5'4". ...

Would these work for women? I'm 5'4". If so, would this work with shorts that have a 5" inseam?

You may have to pull them up to just under the knee to make it up to the Short

True to size and a good cover for your knees, especially up here as the year without a Summer continues. Bicycling magazine reminds us to keep that synovial fluid that lubricates the knee joint warm and these plain lycra warmers do just that.

One very small issue is that if the warmers are not positioned on the thigh correctly, they will ride up your lower leg a little.
