Ive used these several times and my early review is that theyre as described. The material is very stretchy and soft. I live in SoCal and wear these for cycling so that i dont keep getting sunburned (even with sunscreen). I do not wear sunscreen when wearing these arm sleeves and do not get burned at all during 3 hour rides in direct sun. The sweat is pulled off of my skin, keeping me dry. I can feel the cooling effect in the wind from the sweat being pulled away from my arms and drying on the sleeves.They are very long, so fit my long arms. They are very stretchy, so will fit a wide range of builds. I dont have any reason to believe they'd fit a child. Adults only.
