Whether you're overnighting near the beach or car camping at a festival, our 64 oz Wide Mouth bottle makes sure there's more than enough refreshment to go around. And our Colour Last powder coat is dishwasher safe for even more convenience. Cold stays ice cold for 24 hours, and hot stays wickedly hot for 12 - just like always Hydro Flask's largest Standard Mouth available uses TempShield double wall vacuum insulation to keep your water refreshingly ice cold for up to 24 hours. Plus, it resists condensation, so the sides of your bottle stay dry.
