The 14 Oz Quencher features: Say hello to Stanley's smallest and lightest Quencher. Fill this 14 oz tumbler with water to keep your child hydrated. It’s perfectly sized for kids’ use, from their favorite morning refresher to playtime and bedside hydration. Whatever your child’s beverage preference, the vacuum insulation will keep things at the ideal temperature while they drink. The lid features a rotating cover with three positions: an opening for the reusable straw, an opening for sipping, and a full-cover top to prevent splashes.
