The Tundra Hippies are built just like our existing Hippies with the addition of a new, tougher outer material. The new material is twice as tough as our regular Hippies with no noticeable weight increase. The Tundra Hippies are geared toward those more adventurous folks that tend to take the road less traveled to get where they are going. The idea to make a tougher Hippie came from Alaskan hunting guides who wanted a Hippie that could handle the demands of long treks through the varied environment of the Tundra.
