This Simple Modern 40oz trek tumbler in a tie-dye purple cloud color. Durable construction and sleek design, that is cup holder friendly. This tumbler will make sure your drink stays at the perfect temperature for hours. Simple Modern website says it keeps beverage Hot for 12 hrs and Cold for 24 hrs. Purchased personally at Whole Foods a month ago. Some gentle use (for water only), one small mark in lid that I missed when I bought it but mostly sat in cabinet.
