I'm 5'4, 125 lbs and fit. The small ones hug the calves but are not tight for me. Just not as loose as the pictures suggest. Overall, it hasn't been easy to find something like this so I'm pretty stoked. Makes me look taller and V-shaped. But yeah, if you're closer to a normal sized human, you might need to size up.

The general reviews of these joggers have been that the size is wrong.  I have found them to be the perfect fit. I’m a 32 waist and ordered the medium and they are fine 

I’m usually a medium and that’s what I went with here (as that is what the fitting guide suggested). The pants are too small and way too tight. The material seems nice but the fit sucks. Should’ve gone one size up. 

Super comfy trackies - a bit narrower than in the pictures, particularly around the calf. Nonetheless, very comfy and smart enough to wear out of the house. Unfortunately the quality of the stitching on the logo and around the pockets leaves a lot to be desired. Constantly snipping bits off.

These joggers are a great style, however, the sizing is questionable at best. If the model is actually 6'2" he seriously needs to review his training program because he must have a couple of bits of string hanging off those hips under the joggers. I am 6ft and 86kg, cycle a lot and train in the gym most days and these joggers are tighter than an Otters balloon knot in a flood. Please MyProtein use proper athletes for models and sizing. 

Stop deleting my reviews MP. I've tried letting you know the sizing is way off.. I Have a 29" waist and the XXL ones are still far too small. They are like spray ons. The model can't be wearing a the size stated.
