The WALLMUG SLEEK is Rivers' take on the everyday takeout coffee cup, reimagined as a reusable, double-walled tumbler. It keeps the familiar silhouette of a to-go cup, but its vacuum-style double-wall construction lets you skip the cardboard sleeve entirely — the exterior stays comfortable to hold with hot drinks inside, and cold drinks stay condensation-free. Lightweight and tough enough for daily commuting, camping, or travel, it pairs naturally with Rivers' portable coffee drippers for a complete on-the-go coffee setup, and its lid is secure enough for safe use at a desk or bedside.
