MSR Titan Cup
Lightweight, strong, holds a drink very well. Got this for a trip where the water bladders were for the group. Put this under the spigot and had a nice cup of water for every meal.
Holds a warm cup of tea as well but a boiling hot cup is a little too far in my comfort range. I primarily bought this because I had money to spend and an itching for a titanium cup. While car camping I buy the large jugs of water with spigots on them. This cup is overkill for this job, but boy does it look cool(MSR logo etched on the bottom).
