Ridiculously comfortable. Feels like wearing nothing. Be advised - they grow as you wear them. I'm a 28; ordered a 28; and they grew to a 29 by the end of day. Not a big deal to me - they returned to form after washing in cold and hanging to dry. But I would make sure you get them snug...otherwise they'll grow far too large. I loved them enough, I ordered all three colors. Highly, highly recommend.
