This is my second pair of this Tights. The first pair I bought was a Small, which is what I would usually wear (178cm, 81cm waist, 96cm hips), so I returned them, which was pretty straight-forward to do by the way. I then bought a size Large (so two sizes up), and they fit much better. The Tights themselves are great, they're comfortable, breathable, and have a very handy zip-pocket, so I'm not afraid to loose my keys if I go for a run. In defense of MyProtein, the sizing on most of the clothing seems to be fine, this is the only thing I've had such a problem with. Overall I'd recommed these shorts, but make sure to buy them a size or two bigger then the Size-Guide suggests,

I'm 5 ft 8 with 30-32 inch waist and size M just about fit because of the stretch. The description/sizing is a bit misleading as the model is 6'2 and is also M.

These are the best leggings I have tried from MP they are comfortable warm yet breathable and look good. I use them for lower body days where I find shorts or tracksuit can be restrictive especially for squats. Material feels of a good quality. Has a small pocket on the side if you want to use for running or something to hold a key or a card etc, personally don't use though and it doesn't get in the way.
