Until now I have transported all my equipment in my backpack. But a pulka has its advantages, as the tour reports demonstrate. At bit deterring was the fact that a good industry-built pulka weighs 7,5 kg already when it is empty, and that can be a problem in airplanes and buses. This is not the only reason why people build their own pulkas from children's sledges. Here are a few pages with self-built pulkas, and maybe I will build one some day. Maybe an inflatable pulka would also be a solution, I saw one in a picture, but I never found a catalogue where you could buy it.
