Counterfeit lululemon leggings usually fail on three things: the inside tag, the fabric and the hardware. Here is how to check each, with style-specific tells for Align Leggings, Wunder Train Leggings, Wunder Under Leggings.
Check the inside tag first
Genuine lululemon uses crisp, heat-pressed inside tags (older pieces have sewn tags) with a fabric name that matches the style. Blurry printing, misspellings or a fabric name that does not belong to that style are immediate red flags.
Feel the fabric
Leggings from lululemon use specific fabrics: Align Leggings is Nulu; Wunder Train Leggings is Everlux; Wunder Under Leggings is Luxtreme or Luon; Fast and Free Leggings is Nulux. A counterfeit in the wrong fabric feels slippery, thin or stiff compared with the real thing.
Style-specific tells
Align Leggings: Genuine Align has a soft heat-pressed inside tag with a size dot, no sewn-in care label at the waist, and a flat waistband seam with no front seam line.
Wunder Train Leggings: Look for the 'Everlux' fabric wording on the inside tag and the reflective logo at the back waistband.
Wunder Under Leggings: Check the inside tag fabric name; Wunder Under appears in both Luxtreme and Luon and buyers care which.
Fast and Free Leggings: Count the pockets: genuine Fast and Free has side drop-in pockets and a zipped back pocket; fakes often skip the zip.
