The Insulated 18oz Narrow Mouth Bottle by Hydro Flask is neither the smallest nor the biggest of the Hydro Flask bottles. Yet, even Goldilocks would agree, this 18 oz is probably the most versatile. Double wall vacuum insulation removes the air between the two layers of stainless steel, so outside air has a difficult time affecting the temperature of your beverage and vice versa. Simple to clean there is no liner to scratch and it is completely recyclable. Powder coat finish is durable, tough to dent and stays slightly warm to the touch. Unscrew the lid for enough coffee to take your to lunch or share your extra cup of tea with your ski partner.
