Night Sky 3 & 4 Person 2-in-1 Backpacking Tent

Night Sky – 3 & 4 Person 2-in-1 Convertible Backpacking Tent

Lightweight. Versatile. Patented. The Mons Peak IX Night Sky converts between a 4-person setup (yellow base, 94"x82"x55") and a 3-person configuration (green base, 84"x74"x46") in seconds — save ¾ lb by leaving the unused base at home. A full no-see-um mesh canopy delivers unobstructed night-sky views and superior ventilation, making it the go-to tent for star-gazers and thru-hikers alike.
