Fabric is soft - not slippery or shiny. The fit was true to size for me - I am a medium. They feel good; not too tight nor are they falling down during the work-out.
I was impressed. Great quality especially for the price. I didn't have any of the "see-through" issues I saw other reviewers mention.
I have tried several brands of workout pants, ranging in prices. Out of all of them (including Lululemon) these are the best. They are tight enough to stay put while moving, but soft and loose enough to be comfortable all day. The best!
These leggings are great: they're thick, offer good tummy support (my wife is a bit self conscious of her "mommy belly", having given birth to our second child months ago), and the price is unbeatable. My wife uses them both for jogging or under long tunics/short dresses.
I purchased three colors in an XL and I am extremely impressed with the consistency! Each pair fit the same in the waist and thigh and the material was not at all see-through. The black and blue colored leggings were the most figure flattering. Overall, the price point was awesome and I highly recommend trying these out before purchasing a more expensive brand.
