Counterfeit lululemon shorts usually fail on three things: the inside tag, the fabric and the hardware. Here is how to check each, with style-specific tells for Hotty Hot Shorts, Speed Up Shorts, Track That Shorts.
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
Shorts from lululemon use specific fabrics: Hotty Hot Shorts is Swift; Speed Up Shorts is Swift; Track That Shorts is Swift; Align Shorts is Nulu. A counterfeit in the wrong fabric feels slippery, thin or stiff compared with the real thing.
Style-specific tells
Hotty Hot Shorts: Liner is a soft mesh brief; hem has a small reflective logo on the left leg.
Speed Up Shorts: Back zip pocket distinguishes Speed Up from Hotty Hot.
Track That Shorts: 5" length and a flat waistband without a wide front panel.
Align Shorts: Nulu feel and a heat-pressed inside tag match Align leggings.
How ThriftUp authenticates every piece
We check liners for staining, drawcords and inner pockets, and the waistband for stretch.
Any piece that fails a check is removed before grading. Buyers who find a non-authentic piece are covered by our claims policy.
