GSI Outdoors Infinity Mug
Bought this mug to replace my titanium single wall one during winter trips to keep my beverages hot longer.
Not a double wall but does it’s job just as well. We managed to keep hot chocolate and coffee at a very nice temperature in it for 20 minutes while the mug sat on a rock surrounded by snow.
I’m very happy with the design. Easy to hold, easy to drink from. The lid stays put and does not leak.
This mug is a great compromise between single wall and double wall. There is a very small amount of heat the insulation lets through so unlike double wall it has the ability to keep your hands warm but unlike single wall you won’t get burned when you touch it.
