I purchased the arm sun sleeves (in beige) to protect my fair skinned arms from the sun whilst playing tennis and couldn’t be happier with them. I thought the fabric might be a little hot but quite the opposite they kept my arms cool as well and I also thought they might slip down a little when playing but no, they stayed up and did the job perfectly. I purchased size M based on my bicep circumference as recommended on the website. All in all I am very happy with my purchase and wld definitely recommend them to anyone wanting to protect their arms from the fierce Australian sun. It also beats lathering your arms in sticky sunscreen each time you have to go out in the sun 😊
