Starting a NOBO thru hike starting 3/17/21 and just want some last minute opinions on a shelter. My original plan was to take my Nemo Dagger 2P tent. With that and my other gear, it made for a base weight in the 25 pound range. More and more I’ve been thinking of switching to a bivy/tarp combo. I’ve ordered an Outdoor Research Helium bivy but have yet to receive it. Reviews all seem to indicate that when it’s closed up, there’s a lot of condensation buildup inside. I’m thinking with an REI tarp at 115”x115”, if I put that over the bivy, I’d be able to sleep with just the bug net by the head, allowing airflow within. A switch to the bivy/tarp would save about 2 pounds, and I’m thinking that it could be a good way to start off. If the tarp system isn’t to my liking, I can always have the tent sent out to meet me. Thoughts? Thanks for any feedback.
