For a wide variety of reasons, we're big fans of the superlight MSR Hubba Hubba NX 3-Person 3-Season Tent because it packs down small, weighs next to nothing, breathes deeper than our yogi, and still stands up to years of camping adventures. Light in the pack but tough on the ground, the 20D nylon ripstop bathtub floor pulls it weight by protecting our crew and our gear when it starts to rain. Water stays on the outside due to a combination of DWR and PU coatings. Vents on all four sides let the crosswinds blow to keep the inside air fresh. The nylon ripstop rainfly uses PU and silicone coatings to keep water from creeping inside.
