I bought this for my daughter after she had elbow surgery to cover her scar in the sun. She wore it for hours at a time in the water and it didn't come off. Has been washed and dried several times and still holds its shape.

The quality of construction is great, and the material is thick (It's actually sewn as a torus, picture a fabric donut), but it's almost too tight a fit on my petite arms. I have to position it carefully to avoid long term discomfort. When worn around the elbows, as seen in the picture, it just fits, without any wiggle room. Does it stay put? Yes. Does it function as a sweat band? Yes.By petite arms, I primarily mean that my arms are short in length and proportioned differently than the arms of a taller person (I am 5'2), not that my arms are scrawny. 4 of length is a more significant portion of my arm than it would be for most men and women. I have sizing problems that average height adults don't have.

I have ordered several of the wrist, arm and sweatbands. I love them, they`ve been durable and serve their purposes well. I like to use the armbands on my elbows when in the plank position, it provides excellent cushioning again my gym`s rough floor. I will definitely keep ordering.
