@purascans: 🔍 Sourced From Public US & EU Data 🔍 Lululemon’s signature Luon fabric is made from nylon and Lycra — both petroleum-based synthetics. The disperse dyes used on synthetic fabric don’t chemically bond to the fiber and can transfer to skin with heat and friction. The brand also weaves metallic silver into the yarn as an antibacterial finish. Natural fibers like organic cotton and merino avoid all three. Scanned with the Pura App
