The Stanley IceFlow Aerolight Bottle with Flip Straw (24 oz) is a lightweight, double‑wall vacuum‑insulated water bottle built with premium AeroLight spun‑steel technology that makes it significantly lighter than conventional stainless steel bottles while still keeping drinks refreshingly cold for up to about 10 hours and iced for up to around 2 days. It features a Flip Straw 2.0 lid with a larger drinking opening and a built‑in straw that flips up for easy sipping and snaps shut to help prevent leaks, a comfortable recessed grip and easy‑carry handle, BPA‑free construction from 90% recycled 18/8 stainless steel, dishwasher‑safe components, and a slim design that fits most car cup holders—perfect for everyday hydration, workouts, travel, or school.
