lululemon wundertrain black leggings size 12 28”

Great used condition size 12 black lululemon leggings. Length is 28” . I am not positive of the design/ fabric of these leggings, but based upon my other lululemon leggings and the material, I’m assuming these are the old Wunder Under design leggings. I took EXCELLENT care of these leggings- always washed on delicate in cold water and hung up to dry. While there are no rips or holes, there is some piling as pictured however does not effect function. Size is 12 but fits more like a 14. A great pair of leggings.
