PortaVia Lid
A universally fitting, silicone lid that sits inside your chosen container to create a spill-proof seal.
Our West of One tumblers are specifically designed to accommodate the PortaVia lid. Purchase an extra one to swap out between uses . . . plus, use with other mugs and tumblers you already own!
Note: PortaVia fits between 72mm or 2.8" and 82mm or 3.25" in diameter. PortaVia works best on inward draft angles/ tapers.
