With UPC 810028846210, the Outdoor Tumbler combines rugged durability with the premium quality Hydro Flask is known for.
Advanced TempShield Insulation Technology
The Hydro Flask 12 oz Outdoor Tumbler utilizes proprietary TempShield insulation that creates a vacuum between two layers of 18/8 stainless steel. This advanced technology effectively prevents heat transfer, keeping hot drinks piping hot for up to 6 hours and cold drinks refreshingly chilled for up to 24 hours. Whether you’re enjoying morning coffee on a chilly trail or sipping ice-cold water during a summer hike, the OKT12035 maintains your drink’s ideal temperature far longer than standard tumblers.
The tumbler’s durable powder-coated finish provides a strong, non-slip grip and resists scratches, chips, and fading, making it ideal for rugged outdoor use. The 12 oz size strikes the perfect balance between portability and capacity, fitting comfortably in most cup holders and backpack side pockets.
