2XU Men's Flight Compression Socks - Performance Running & Travel Socks for Athletes - Improve Circulation & Reduce Fatigue - Ideal for Running, Flying & Recovery

I did a decent amount of research before ordering these, I need upper arm and elbow compression and I needed it to be snug and functional. The problem? Though they're not huge by any means, my upper arms are a decent size at 17 inches. Some of the other sleeves are great but wouldn't fit me at all. I bought the XXL 2XUs and they fit perfectly. They're very comfortable, snug, yet allow range of motion and freedom enough to workout while wearing them. They give the necessary support without being restrictive.I highly recommend them.
