Nemo equipped the Tenshi Tent with Extreme Conditions Technology for 4 season protection when you're climbing, backpacking, and exploring the alpine. Extreme Conditions Technology includes highly weather protective features to keep you comfortable and dry in snowstorms and rainstorms. The tent's Osmo body works with a PU coated floor and vestibule to keep wetness at bay, and Nemo's patented Pressure Porting ensures sufficient airflow even in blizzards. Nemo also added a Condensation Curtain that falls from the top of the tent to the bottom, just below your head, in order to block your breath's condensation. You can deploy the vents up top from the inside to get more air after the storm. The Tenshi also features a Sleep Tight Anchor Transfer for big wall climbers, and the Snow Skirt adds extra protection below the tent. Triangulated guyouts, stakes, and a stuff sack make for an easy cleanup and setup.
