Really love this product05/19/2019 ByJane Julius I am an Age Group Triathlete. I have purchased many of the Arm Sleeves and Skull Caps for my outdoor training and races. They have helped me finish 2 Ironman Races. We have customized the Pink Caps to match our Tri-Kits. They have solved the sunburn problem on arms and head. They are well-made and hold their shape and color. I also use them for any other outdoor sport.
