The 12oz Wide Flex Sip Lid Flask is the perfect all-rounder, with a small, neat design that is perfect for carrying your tea, coffee or cold drink. Made with 18/8 pro-grade stainless steel, the flask is intensely rugged, protecting taste with a no-flavour transfer guarantee. Meanwhile, the proprietary powder coating further boosts grip and adds an extra layer of durability. The flask is also engineered with Hydro Flask’s unique TempShield™ technology, which uses double wall vacuum insulation to protect the temperature of your beverage. It keeps hot drinks pipping hot, and it keeps cold drinks icy.
