The Hipster is a replacement for the backpack if you just can’t seem to lug around enough stuff carrying everything on your shoulders. The designer, Joel Hoag, created the Hipster in response to his father’s wish to walk across America, and he hopes that his design will lead to the growth of a sport he calls “adventure walking”. So far there are two designs, the Hipster I, which utilizes a single wheel, making it maneuverable and compact, and the Hipster II, with two wheels for greater strength and easier carrying of heavier loads. Though you are sure to garner quite a bit of attention looking like you forgot your bike on a cross country trip, it does save your back from sure destruction if you tried to load everything in a backpack, so it’s a good use of function over form. I think it’d be fun to attach a few of these together and form a new sport called “human train adventure walking”, but that’s just me.
