Most are designed to be more leakproof than reusable cups. However, we found from our testing that some still leak easily, even when advertised with phrases such as 'leak-resistant'.If your top priority is temperature regulation and insulation, opt for a travel coffee mug made with vacuum-sealed stainless steel. This material can keep drinks hot for up to eight hours — in other words, a full day's work for many. However, stainless steel can affect the taste of your coffee if you also use it with other flavored liquids, as it's prone to imparting notes from past drinks into your current brew. Over to Germany now with a look at this stylish travel mug from 720 Dgree – a company founded with the intention of reducing single-use bottles and cups in an effort to promote a more sustainable way of living. Available in plenty of different colours, all with a classic stainless steel base, these have become iconic in their own right. You probably know someone with a Bodum mug.

Fuss-free maintenance: It has a convenient two-part lid for thorough cleaning and all parts are dishwasher friendly. Just pop it in with your other dishes and it’ll be ready to go again.

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. Next up we have a Classic from a classic travel mug producer – Stanley. Founded in 1913 when William Stanley Jr fused vacuum insulation with steel to make a portable drinks bottle – and they have been developing that original design for over a century since. Aesthetically, it comes across as a solid little bottle – it may not look beautiful, but it is not supposed to. This isn’t for walking around town with, this is for adventures. The insulation is good – your drink will stay hot for five hours, or stay cold for up to 12 hours. It also has a ‘sweat proof’ design, which prevents condensation on the outside of the mug.
