The Kelty Quartz 4 is a simple, lightweight tent for all seasons. Configured with two doors and two vestibules, the floorplan maximizes the available living space. Two DAC pressfit poles slide into vaulted pole sleeves and once engaged a patented FlyBoy anchoring system prevents stretching or movement, even in high winds. The vented ripstop rainfly has a clear window so you can check out the weather without opening up (unless, of course, its iced over or youre snowed under). Versatile, the fly can be set up alone or with a footprint [KEL0301] for an ultralight shelter. Other features include closable mesh panels and taped seams to keep out the elements, internal storage pockets and gear loft loops to help you keep organized, noiseless zipper pulls and an easy buckle tent/fly connection.
