These are my 7th or 8th pair of compression leggings I’ve bought from 2XU over the last 10 years. They used to sell leggings with firmer compression, which I prefer. These pants are considered “light” graduated compression which surprisingly helps for my leg workouts almost as good as the firmer compression pants they used to sell. Love the green! So glad I bought them when I did, my size is sold out now. If your size is on the higher end of the range or in between sizing, then sizing up won’t be as tight, while sizing down will give you more compression, which is what I like. For reference, I’m 5’5” and 112 lbs. According to the size chart, I almost between a small and XS. I get the XS for firmer compression.
