These Lululemon free stride running tights are made of Nulux™ fabric that's so smooth and lightweight, I ordered them twice. Or at least, I thought I did. I actually ordered them three times by mistake and am now selling the third pair. They are absolutely fantastic, but I do NOT need three pairs. They are brand new, have not even been tried on, and in pristine condition. I ordered these directly from Lululemon, so any slight creases visible in the photos are just from being folded and packaged for shipping. There are no marks.
