Manna Boulder Vacuum Mug

Thanks to its double-walled vacuum insulation, this mug is designed to maintain beverage temperatures for extended periods. While exact times vary based on ambient temperature and how often you open the lid, it is built to keep drinks hot or cold throughout your morning commute or campsite breakfast.

The lid features a sliding closure designed to minimize spills and splashes while you are on the go. However, it is not 100% leak-proof, so it is best to keep the mug upright in your bag rather than tossing it in loose.

The handle features a distinct square shape, which provides a more stable and ergonomic grip than standard rounded handles. It is designed to feel secure in your hand, even when you are wearing gloves or moving around a campsite.

While the stainless steel body is durable, we recommend hand washing the mug to preserve the integrity of the vacuum seal and the finish. The #5 PP plastic lid can typically be placed on the top rack of a dishwasher, but hand washing is generally safer for long-term use.

With a 14 oz capacity, the Boulder Vacuum Mug has a relatively compact footprint that fits comfortably in most standard vehicle cup holders. Its design balances a generous serving size with portability.
