I love my bivvy. Its so easy to deploy my entire sleep system. I literally just unroll my bivvy blow up the air mattress that's already inside and hop in my sleeping bag that is also already inside. It takes a minute max to go from not deployed at all to entirely set up, and I get to sleep under the stars. If it starts raining i just zip up and I'm set. It simplifies packing because my shelter, air mattress, and sleeping bag all just roll up and get put in a stuff sack. They are fairly light and relatively cheap. If your just one person it honestly cant be beat but I never see anyone talking about them.
