This large bottle is excellent for holding and carrying beverages for long periods while preserving the temperature. The water bottle's stainless steel interior is double-walled and has vacuum insulation to conserve hot and cold drinks for up to 24 hours. This bottle's large capacity (32 fluid ounces) deems it ideal for any hard-working athlete or construction worker, and the included rubber wristlet attached to the cap makes the bottle convenient to carry on the go. As with all stainless steel water bottles, hand washing is recommended to keep them in pristine condition.
