We might as well start off with sleeping quarters.
I used a Outdoor Research bivy. The bivy is light but it is confined. I also found that you get a lot of condensation inside. That may not happen to you since I am full of hot air.
I would put some of my clothes in the foot of my sleeping bag and used other clothes as my pillow. This about all you can put inside.
My partner used my one man Eureka tent. This tent was also light but did not pack down into as small a package as my bivy. It had more room and less condensation. You could also keep much of your gear inside. I had to leave a lot of gear exposed under the tarp.
I like either one. The bivy is a little lighter and packs down into a small package. I will probably continue to use my bivy though. Especially since I didn't put my name on my tent and can't find it. Hmmm I wonder where that went?
The Tyvek tarp was a life saver. You never know what type of weather you will get out there. With the weather we had I would have been in trouble with just my bivy. I think the tent also would have been less comfortable. It also gave us a weather proof area to store our gear and if we each brought our own we would have had much more comfortable living space.
I had a self inflating pad while my partner had a foam pad. The self inflating pad compacts nicely and is comfortable. If it pops you will be sleeping with no padding. I bought a light weight foam pad that packs down small too. I am going to try that before I go and may take that one instead. Since we are going in on horseback I may even bring both. The pad is also comfortable but not as much as the self inflating. It also doesn't pack as well.
My bivy and sleeping pad are packed into the black mesh pocket on my pack. The black stuff sack holds my bivy while the green has my sleeping pad. My sleeping bag may also in the mesh bag but behind the other bags or I may have put it in the fanny pack with my cooking supplies. It packs down to a smaller bag and I stored in both places during this trip.
You can see my partner's sleeping pad - a mile away! I am pretty sure the blue bag attached to his pack is his sleeping bag. He also had a light down bag but it was heavier than the Marmot Helium and didn't pack down into as small a footprint.
I am 6' but I bought the extra tall Marmot Helium down sleeping back. It fits people up to 6'6". I bought this one because I like room in my sleeping bag and I can keep some of my clothes in it to keep them warm and dry for the morning. I also had to get the longer bag because I know my partner may need to borrow it one day - and yes I made sure to put my name in it! Ha!
This bag is warm to very cold temperatures and packs down to a very small package.
The orange pad you see is my self inflating pad. You can really see now how it packs down small compared to how you see it here.
