When you’re hiking in cold weather or driving to a faraway campsite, a warming hot drink can help lift the spirits. Insulated travel mugs keep teas, coffees and hot chocolate warm for hours at a time, but they’re not all equal when it comes to performance and usability.

The best travel mugs are highly insulated, easy to use and – vitally – leakproof. We’ve put nine of the biggest brands to the test to find out which we’d take on our next hike or camping trip.

How we tested the travel mugs

  • Filled them with hot water and tested the temperature every hour (it’s worth remembering some heat escaped every time we opened the lid, and bigger cups naturally tend to perform better than smaller ones) 
  • Shook them to test for leaking
  • Judged them on looks, durability and practicality

 

Best travel mugs for hiking

This graph shows how well the travel mugs kept drinks warm over five hours. While they all started off at almost 90°C, some had dipped below 40°C by the end of the test. The list on the right ranks the cups from best to worst.

Thermos King Can

5.0 out of 5 star rating

Best for long hikes

""

Pros: great heat retention, ergonomic shape, feels durable, easy-to-use cap

Cons: twist cap can be stiff with hot drinks

  • 7 hours hot, 18 hours cold (according to product spec)
  • 360g for 470ml capacity
  • Dishwasher safe
  • Leakproof

We had high expectations from Thermos’s King Can, and it’s fair to say we weren’t disappointed. The mug topped the charts in our heat retention test, alongside the Yeti Rambler, and its contents were still too hot to drink five hours after filling it with boiling water. We’d recommend getting your favourite beverage to a drinkable temperature before pouring it into the Thermos.

The travel mug feels sturdy in the hand, and has a pleasing ergonomic shape – presumably so the base fits into car cup holders. The lid’s open/close mechanism is different to all the others we tested; just twist the central dial in either direction when you need to take a sip. We found it could be stiff to turn when we filled the cup with a hot drink, but it moves smoothly and doesn’t let any liquid escape when in the ‘closed’ position.

The Thermos King mug comes in some fairly unusual colours, too. We love the understated sage green, but you can also get it in raspberry and copper.
