I was introduced to these pants last summer when a sales associate told me "These will change your life." I thought she was pulling my leg but now they're taking over my work wardrobe. They're spectacularly comfortable (stretchy is good!) and easy to care for (I never need to iron them).The only "issue" I've encountered is that, with many synthetic fabrics, they can make some noise if your legs rub together. While my pants are black, I'm not a ninja so the occasional faint rubbing sound isn't a big deal to me.
