How to use: Simply open the bottle's lid and fill it with your favorite drink or add ice cubes through the wide opening. You can carry it on your hikes or backpacking trips by placing it in your pack. It's easy to grab and take a sip whenever you're thirsty. Precautions: Avoid dropping the bottle from a high place as it may damage the insulation or the bottle itself. Don't use abrasive cleaners on the bottle. Maintenance: Wash the bottle regularly with mild soap and warm water. Let it dry completely before closing the lid to prevent mold growth. If there's a strong odor inside the bottle, you can soak it with a mixture of baking soda and water for a while and then rinse it thoroughly.
