Wunder Under Leggings (Luxtreme or Luon, $98–$118 retail) is one of the most copied lululemon pieces. Check the inside tag fabric name; Wunder Under appears in both Luxtreme and Luon and buyers care which. This guide walks through the tag, fabric, construction and hardware checks we run on every piece.
The inside tag
The inside tag must say 'Luxtreme or Luon' or the fabric family that matches Wunder Under Leggings. Printing is crisp and the tag is heat-pressed on recent pieces. A sewn-in care label at the waist or collar on a recent piece is a warning sign.
Fabric and construction
The original lululemon legging, made in Luxtreme (smooth, cool) or Luon (soft, matte). Many older pieces still circulate in excellent condition.
