Nothing more miserable than waking up soaking wet. Learning to sleep under trees, not out in the open, was key to me staying (mostly) dry. Skurka’s page on site selection really helped drill into my head how important it is.
Double wall tent for the win. Totally worth the few ounces to me to have that separation and keep the sleeping kit as dry as possible. I have been using the sierra designs high route 1p this season and it’s been stellar.
My new tent has tons of ventilation, so I got no condensation when I tested it. If you completely batten down the hatches and have no ventilation, you are guaranteed to get some condensation.
