I've been happy with these tights! They keep my legs much, much warmer than shorts, and aren't flappy like running in sweats would be, and I think they might be a bit more wind-resistant too. They are tights that are right up against you (they are form-fitting spandex), but they are not uncomfortably tight-feeling like some of that compression-wear stuff can be, so if you don't want that squished feeling, these will be good for you. They have just a bit of soft fuzz on the inside that adds the warmth. They do have kind of an odd offset pocket/slot in the back-I think it might hold an iphone securely, but maybe not other phones and I'm not so sure I'd trust it-but since that isn't something I need, it doesn't bother me. These tights wouldn't work above mid-50's or so since they'd be too warm, but above that you can switch back to shorts anyway for running. Not sure how well they'd work below 30 or so-could be warm enough given that you're running, but I didn't try it.
