Using your Sea to Summit Passage Bowl is a breeze. You can fill it with hot or cold food, and thanks to the Cool Grip sidewalls, you can hold it safely even when the food is piping hot. When it comes to cleaning, you have two options: you can either wash it by hand with some mild dish soap or simply pop it in the dishwasher. Since it's microwave - safe, you can also heat up your food right in the bowl. Just make sure not to use it on direct heat sources like stoves. To keep your bowl in great shape, avoid using abrasive cleaners that could scratch the surface. And if you're going on a trip, take advantage of its stackable design and nest it inside the Frontier Pots for easy and space - efficient packing. Remember, this product comes with a lifetime guarantee from Sea to Summit, so you can use it with confidence.
