94% recycled polyester 6% elastane In excellent preowned condition, one flaw noted- see photos for small dark spot on the seat. It may wash out- I haven’t tried. That Patagonia quality though! These tights have one side zipper pocket for phone, keys or a snack. Drawstring closure and wide comfortable non-chafing waistband. Double fleecy layer for warmth for running or hiking in the snow or colder weather. Thank you for looking! Check my other items to bundle and save. Lightning fast shipping. Questions welcomed. Smoke free home. Please review photos and measurements as they are a part of the description.
