DescriptionThe Trinken Lid was invented after wanting to have a cold beer in a covert manner. Simply open your can of choice, snap it into the bottom of the lid, and pop the lid on the cup. Instant stealth beer cozy! By suspending your beer inside the cup, the layer of air insulates your can, keeping it cold in the summer and your hands warm in the winter. Trinken Lids features an ergonomically designed rim and spout that is much nicer to drink out of than a regular can. In addition, the secondary air hole keeps your beer flowing smoothly. After trying Trinken you'll never want to drink out of a can again.
