Key Features

• Fits Inside the Mug, NOT Over the Rim: Porta Via’s flexible silicone lid slides inside your favorite mug to create a snug seal against the inner wall—helping preserve flavor better than plastic or steel travel cups and accommodate handmade ceramic rims when sizing matches.
• MEASURE BEFORE ORDERING: The Medium-sized lid fits cups, mugs, and tumblers with an inside diameter of 3" to 3¼" (76–83mm). It does NOT fit all mugs. Please verify your mug dimensions prior to purchase or select the appropriate sized lid for your needs.
• Lid for Coffee Mug & Popular Brands (When Sized Correctly): Designed to fit your personal mug and compatible with many brands like Yeti, Ember, Starbucks, Miir, KeepCup, and Hydro Flask when sizing matches.
• Keeps Coffee Hot Longer: No need to rush your morning coffee. The Porta Via Lid helps seal in heat for up to 30 minutes, so your drink stays warm during commutes or errands.
• Dishwasher-Safe, Reusable & Planet-Safe: Skip buying another tumbler. Made from reusable, food-grade silicone, this spill-resistant lid is easy to clean and built for daily use. A planet-safe alternative to disposable coffee cup lids at home or your favorite coffee shop.
