The Double-Insulated Classic brings superior performance in a crisp, clean design. Whatever your needs, we have you covered. These bottles feature our signature TempLock™ technology, keeping your favorite beverage cold for 24 hours or hot for 12. However, we didn't stop there. Our high grade 18/8 stainless steel protects from flavor transfer on the inside and will always be sweat free on the outside. Our premium NoSlip™ powder coating on the exterior keeps your bottle in your hands when you need it.
