These survival shelters from Lifesytems could be classed as a bivi in that they are small, lightweight shelters. Not a traditional bivi shape and therefore more of an emergency shelter but nonetheless if you need protection from the elements while walking or hiking these shelters offer a superb lightweight solution. Whether you hike alone or routinely hike in groups these systems can be ideal for short breaks, reading maps or generally anything that requires temporary shelter from the wind and rain. Lifesystems shelters come in either a 2 or 4 person option.
