They are great My arms used to feel as if they were burning each day I was out. But no more. You just feel the coolness.
I do home health in Houston, and this summer my left arm has been baking in the sun, to the point of misery. My husband suggested a UV sleeve (I had never heard of any such thing)... and I found these and ordered a pair. Worked like a champ and I only wish I would have gotten some sooner!
Great product and great value.
