I wear this knee sleeve when my patello-femoral symptoms are acting up and it helps. It is comfortable and fits easily under my tights. I also have the thigh sleeve and I can wear the two together if necessary.
This is a good product. It serves the purpose it was designed for, but I prefer the old design of the narrow upper band. it seems to hold its place better. The new design seems to flare out more in the upper half and even with the wider upper band does not hold its place as well. The old design was an L/XL. I bought the XL not realizing it had been redesigned and was too loose. I sent it back for the L. I will continue to use the product since I can't find anything better.
I had to return it, my previous one said L/XL so i order a XL, it was too big so i had to reorder a Large.
The knee sleeve stays put and is comfortable. It is a life saver on long runs.
Fantastic! No swelling, muscle spasms or fatigue.
