No Leaks– We all know steam rises and hot air causes pressure. When putting the lid on your cup make sure the drinking cap is open. This allows the lid to go on securely without any air pressure to compete with. Close the drinking flap, shake over a sink (just to be sure you screwed it on properly) and off you go. No matter the material, just make sure the insulated mug you choose is approved for use with hot drinks and not just cold ones. One downside of this expensive travel mug (apart from the price tag) is that if you're a 16oz coffee drinker or more, this mug might not be big enough. Its only size is a 12oz/355ml and there's no option at the moment to size up or down.

Lid: The best coffee travel mugs have leak, or spill-proof seals, to ensure no liquid escapes while traveling. We tested the lids on each model to see how durable they are— and also, how easy they are to drink from. A nice touch is measurements marked on the inside of the cup to show your barista where to fill for your favorite 8oz or 12oz brew. Made from 18/10 stainless steel, it weighs just 268g unfilled and features a screw-on lid with a silicone seal that, despite us trying quite hard, helped this cup live up to its maker’s boasts of it being totally leak-proof.The brand claims to keep your beverage hot for 12 hours and cold for 24 hours, and although it kept our coffee hot, by the time the 10th hour came, it was more on the warm/room temperature side - so it didn't quite live up to that 12 hour claim. But, if you're looking for a cute portable mug to keep your coffee hot throughout your 8-hour work shift or school day, this W&P insulated bottle is a great option. Going for ceramic or glass travel mugs will help maintain the flavor of your coffee or tea. They're also easier to clean since you can pop them right in the dishwasher. However, they won't hold the heat of your drink as well as other materials. In other words, if you just want something to keep at your desk, a ceramic or glass coffee travel mug will suit just fine.
