Use the chart below as reference to determine your size. If you are on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest and waist correspond to two different suggested sizes, order the size indicated by your chest measurement.
I was lucky enough to get a hand on these prior launching and testing them. I've been wearing them for about a year now and they are definitively still one of my favorite leggings I've got for my rock climbing workout and running. Super comfortable, durable and protective! Great quality! I love them! I also love the fact that my big smart phone fits in the open side pockets and it hasn't fallen out yet. I really appreciate the practicality of it! Hopefully AOXOR will eventually be able to ship overseas so I can get some more! Definitively recommend those!
