I have purchased Develops Compression pants before, but I like these better. Previous versions have been made of thicker material. These compression pants are super lightweight and feel as though they have been painted on my body. The material is comfortable and appears to be durable after several washings. Don't ever make the mistake of putting them in the dryer. You will not be happy. It appears as though these compression pants will hold their firm elasticity. I will always look for this brand. This two pack of leggings is a great deal. I now have 4 of these compression pants. My other compression pants will get very lonely because these offer a better fit and look. Well-done!
