The OG Lululemon pant, the leggings that launched a thousand ships, the Wunder Under Hi-Rise 7/8 Tight ($98) is an icon of its time. This is the pant that makes your butt look good. It comes in two fabrics, Luon and Luxtreme. The Luon feels more like cotton, while the Luxtreme is designed more for sweat-wicking purposes. All in all, though, this is a thicker legging and is better for yoga or Pilates vs. running or Spin class.
