Leak-Proof Insulated Coffee Mug with Slide-Lock Lid - Matte Black

Founded in 2013, Fellow is a group of coffee lovers, designers, and tinkerers based in San Francisco with team members across the world. Driven by a mission to elevate everyday rituals into moments that matter, Fellow designs beautiful precision kitchenware that inspires everyone to be more curious, creative, and playful.

The brand's first product, the Duo, was launched on Kickstarter. This was followed by their iconic Stagg Pour-Over Kettle in 2014, which cemented Fellow's position as a leader in the specialty coffee world. Two years later, the Stagg EKG electric kettle was introduced, quickly becoming the gold standard for home brewers and champion baristas alike.

Today, Fellow has over one million customers worldwide. The brand remains committed to its roots, reimagining each new product with thoughtful features and design, taking as long as necessary to get it right.

The Carter travel coffee mugs are the latest example of Fellow's dedication to functional, stylish kitchenware. Ready for any adventure, whether by car, bike, or backpack, these leak-proof, slim, and sleek tumblers feature a slide-lock lid that opens and closes with a flick of the thumb. The 304 18/8 double-wall vacuum-insulated stainless steel construction retains heat or cold for up to 6 hours.

Designed to be compatible with on-the-go lifestyles, the Carter mugs fit comfortably in most cupholders. The leak-proof seal and slide-lock lid ensure your bag stays dry, while the durable, BPA-free material becomes more sustainable with every refill. In fact, an independent audit by Tunley Engineering found that the Carter tumblers become carbon neutral after approximately 27 uses, replacing disposable cups.

Beyond functionality, the Carter mugs also prioritize taste. Unlike stainless steel, the ceramic interior coating keeps your brew pure and free of lingering odors, oils, and off-flavors. This true taste experience is the result of Fellow's expertise in coffee and their love for thoughtful product design.

Whether you're a coffee aficionado or a beginner, Fellow invites you to find the joy in the brewing process. From electric kettles and grinders to French presses and scales, the brand's award-winning products are made to elevate your everyday rituals. With their unwavering commitment to quality and innovation, Fellow continues to lead the specialty coffee industry, one beautifully crafted item at a time.
