The Free Zip is the latest freestanding tent to emerge from the Florida swamplands, historic home of Zpacks, the great purveyors of all things ultralight. Like a mutant hybrid conceived in the shadowy ooze where alligators and pythons tangle, this tent combines the lightweight minimalism of trekking pole shelters with the traditional domed support of dedicated tent poles. Yet with a combination of simple design and Dyneema Composite Fabric (DCF), the Free Zip promises to be both more user-friendly and versatile than either.
