NTP-STAG announced it has added Planetary Design, producers of coffee presses, tumblers and airtight food storage containers, to its accessories category.

According to a press release, the Bonner, Mont.-based company developed on-the-go brewing and storage solutions.

Its flagship product is an outdoor-friendly French press mug called the Double Shot. Dubbing it the “commuter mug of the future,” the two-in-one coffee maker and travel tumbler holds a secret twist-off compartment for storing extra grinds, tea bags, sugar and snacks.
