Just wondering...Do any of you use embrocation AND wear knee warmers or tights? Seems to me that in the cold, tights help warm the entire leg and using embrocation under the tights would focus on keeping the knee flexible and protected. When riders apply it to the neck, etc., it's obvious that they coverup with a jersey, jacket or more. Is it different for knees? The descriptions on most of the sites selling embrocation claim that using it makes warmers and tights unnecessary.
