I nearly always have tea with me on the trail. That and a couple honey packets. In most cases I just carry Celestial Seasonings herbal teas. I buy the sampler pack they sell, where you get 5 flavors in packs of 3 to 4 bags. They roll down nicely once opened and stay reasonably fresh.
Otherwise I do have fillable bags where I can add whatever loose leaf tea I want! You can find them in many stores with the tea.
