Counterfeit lululemon jackets & outerwear usually fail on three things: the inside tag, the fabric and the hardware. Here is how to check each, with style-specific tells for Define Jacket, Scuba Full-Zip Hoodie, Cross Chill Jacket.
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
Jackets & Outerwear from lululemon use specific fabrics: Define Jacket is Luon or Nulu; Scuba Full-Zip Hoodie is Cotton-blend fleece; Cross Chill Jacket is RepelShell; Down for It All Vest is Glyde with 700-fill goose down. A counterfeit in the wrong fabric feels slippery, thin or stiff compared with the real thing.
Style-specific tells
Define Jacket: Genuine Define has a metal zipper pull with the lululemon logo, thumbholes with cuff tabs and a small inside pocket.
Scuba Full-Zip Hoodie: Zipper pull engraved with the logo; hood lining is a ribbed or terry fabric.
Cross Chill Jacket: Seam tape visible inside; RepelShell wording on the tag.
Down for It All Vest: Check for leaking down and the fill-power wording on the inside tag.
