Engineered for dockside hangouts, campfires, and long days on the water, our branded 28oz Yukon Outfitters Brew Boss bridges the gap between a high-capacity travel mug and a rugged thermal stein. Built from heavy-gauge 18/8 (304) kitchen-grade stainless steel, this double-wall vacuum-insulated mug features an internal copper-plated core that locks in temperature to keep beverages crisp and ice-cold for up to 24 hours or steaming hot for up to 6 hours.

The Brew Boss is equipped with an ergonomic, heavy-duty welded grip handle that provides balanced control even when filled to capacity. Inside, laser-etched graduated fill lines allow easy measuring when mixing drinks or pouring liquids. The exterior is coated in a durable, sweat-free finish supported by a non-slip silicone bottom bumper pad that eliminates clanking on boat gunwales and keeps the stein planted on slick surfaces. Finished with a shatter-resistant, splash-proof Tritan polymer slider lid, it is 100% BPA- and lead-free.
