These are cute leggings, but as a huge fan of nylon leggings because of the great stretch they have, these are a bit restrictive and makes me wonder if they truly have as much nylon as claimed. They do stretch, but they are super tight for a large.These leggings are made in PRC (china). The 80% nylon and 20% spandex fabric mix (according to the label inside the waist) has a bit of stretch. I sized down to a medium, and they are tight right where I need them, my legs. The waistband keeps sliding down during my sit ups, and I did not make to a jog before having to pull them up frequently (a better waistband or drawstring would fix that). The fabric is thick enough to pass a squat test. I did not find any flaws in the fabric or stitching when I took them out of the bag. These leggings can be better with some attention at the factory to the fit around the waist.4 starsThese Yoga Leggings have the wrong fabric description, they are 80% Nylon, 20% Spandex, and the description says 87% Polyester, 13% Spandex. Because it is really difficult to order according to the size chart (they are really small measures) I ordered the Size small according to the type of fabric, and they are very tight, I cannot use them.I have a pair of leggings with the same fabric they describe (87% Polyester, 13% Spandex) and they fit me perfectly in size small, that’s why I chose a small size, my regular size is Medium. Based on this experience I could say they are true to size, or for a not too tight fit you can size up. For reference, I’m 5’4”, around 150 pounds, 31” waist, 38” hips, I think size Medium would fit me.On the other hand, they are lightweight, stretchy, the pockets are deep enough, appears to be a durable pair of leggings, material is non see-through and tummy control is good. Overall, they are ideal for sports activities.These are definitely my type of leggings. They have the stretch, full coverage, and comfort but the sizing is a bit off. I ordered an XL and it says it's a size 10. They are snug. I can stretch the upper seams to get a better fit but if this isn't something you wanna do definitely size up. The pockets were a plus!The size on these were smaller than I expected. I'm a size 12/14 in regular clothes. Though with lululemon I were a size 10 so I was willing to give these a try. They definitely were snug and the high rise was not so high and kept slipping down. Maybe if you are a size 10 and you like your workout clothes snug will these work. The material was nice and comfy.I got these for my wife and she said:They fit exactly like the picture at mid waist to just above the ankle. I am 5’2’ 140 Lbs., I ordered the size 8 Large. They are 80% Nylon, 20% Spandex, machine wash. I am constantly in motion, these pants stay in place, no need for adjusting. DOG MOM APPROVED. I love these pants, because they don’t attract dog hair, and the little nose and paw prints I get throughout the day wipe off clean with a damp cloth.These are soft and a nice length for taller girls. They fit well, stay up. Come down to my ankle bone. They are a def keeper.For reference I am 5'10" 110lbs, usually wear a small-small. These are a small and fit great.
