I have used this mug for a number of outings now and am very pleased with it! Aside from the obvious (It's ability to retain liquid for drinking!!) it excels in it's performance in my eyes! It is exceptionally light and adds no weight to a rucksack carried for any lengthy period. It is double walled and therefore insulated to a fashion and keeps a hot drink nice and warm for a good spell. Easy clean and hooks nicely to the exterior of your rucksack with the aid of a carabiner. (Not supplied!) Bought at a bargain price and delivered swiftly by Amazon.
The Gelert is the best double wall mug available. The double wall keeps the contents warm for longer when used ouitdoors. The hollow steel handle stays cool for a comfortable grip. The handle is also welded to the mug,this is a key feature as many alternatives have plastic handles which are very easily broken. Great value too.
