With the Hydro Flask 32 oz (936 ml) travel mug, you can carry more liquid and refill less often. The double-wall vacuum insulation of TempShield keeps drinks cold for hours, while the clear, sturdy lid and flexible straw make drinking easy and splash-proof. The strong ergonomic handle ensures comfortable carrying, and the wide opening accommodates ice cubes for extra refreshment. This mug is dishwasher safe, made from durable stainless steel, and fits in most cup holders for hydration on the go.
