My sweet little 4 yr old granddaughter got burned on her arm by a hot cup of tea. Being summer and living on a island, I wanted to keep her arm covered and out of the sun while she enjoyed outdoor activities. These sleeves did the trick. She wears just one so it’s great to have a spare. She loves it and wears it without being told. I ordered the size small and she does say it doesn’t always stay up but it covers her burns and that’s most important thing.
