Sea to Summit Horizon Insulated Mug - Brown - 475ml

The Sea to Summit Horizon Insulated Mug has a capacity of 475ml (16 fl oz). Note that the product description also mentions 335ml | 11.79 fl oz, which might refer to a different model or measurement of usable volume without the lid.

The lid is designed for sipping and is a press-fit style. While it helps minimize spills, it is not guaranteed to be completely leak-proof if tipped over or subjected to significant pressure.

No, this mug is not designed for direct heating over a flame or stovetop. It is microwave safe for reheating, but should not be used as a primary cooking vessel.

The mug is made from BPA-free, glass-reinforced polypropylene, which is food-grade, lightweight, and durable.

The double-walled construction provides insulation to maintain temperature longer than a single-walled mug. However, it is not a vacuum-insulated flask and will not keep drinks hot or cold for many hours.

Yes, the mug is dishwasher safe, making cleaning convenient.

Cool Grip refers to the fluted and ribbed design of the mug's exterior walls. This creates an air gap and provides insulation, preventing your hands from feeling the extreme heat or cold of the beverage inside.

Ensure the rim of the mug and the inside of the lid are clean and dry. Align the lid carefully and press down firmly. If removing, gently twist and pull.

Pre-heat or pre-cool the mug with hot or cold water for a few minutes before filling. Ensure the lid is properly sealed. Note that this mug provides insulation but is not a vacuum-sealed thermal flask for extended periods.

While the Cool Grip is designed to minimize heat transfer, extremely hot liquids can still transfer some heat. Allow the beverage to cool slightly, or ensure the ribbed walls are providing adequate grip.

Wash immediately after use. For stubborn stains or odors, try a mixture of baking soda and water, let it sit for a while, then rinse thoroughly. Ensure it is completely dry after cleaning.
