A rugged, vacuum-insulated vessel built to keep large volumes of draft beer or other beverages at the perfect temperature. It prioritizes durability and temperature retention over portability features like handles or slim profiles.

This is the gold standard for keeping a full half-gallon of craft beer or cold brew perfectly chilled for days. While its sheer size makes it a commitment to carry, the airtight Swing Lok cap ensures your carbonation stays crisp and your pack stays dry.

This half-gallon vessel is the ultimate hydration station for long hauls, trading portability for sheer volume. The ceramic-lined interior is the real game-changer, finally eliminating that persistent metallic aftertaste common in stainless steel bottles. It’s bulky, but for all-day temperature retention, it’s unbeatable.
