Listings most commonly list nylon, polyester, or a blended/upgraded fabric called Aqua X. Descriptions consistently note high elasticity for a snug, comfortable fit and mention zero-pilling for long-lasting wear.

Many listings advertise strong UV protection, with some specifying a UPF rating of 50+ and claims of blocking about 99% of UVA and UVB rays. Other products say the fabric is treated with an ultraviolet light absorber. Check each product page for the exact UPF or testing details.

Follow manufacturer guidance: clean with water and a mild detergent, avoid bleach, and either hand wash or wash inside out. Drip-dry or air-dry rather than tumble-drying to preserve fabric and print.

Product descriptions highlight reinforced seams and strong tear resistance for durability. Some sleeves include anti-slip gel or textured inner surfaces to help keep the sleeve in place during activity.

Pack sizes vary from single pairs to multi-pair sets and multi-piece costume packs. Examples in listings include "1 Pair," "4 Pairs," and a costume set listed as "Number of Pieces: 6."
