I am still dialing in my sleep system and need some help. I am mostly a side sleeper, but often wake up on my back. I am also 6'3". I had been using a Prolite 3 short pad, with a GG Nightlight 3/4 under it. Last summer and fall I started just using the Prolite 3 and put my pack under my feet like some here do. I use a Granite Gear Lattitude Vapor, a larger volume, and heavier, panel-loading pack built like the Vapor Trail. Once I get most of my other gear to a point where I wont be changing it much I will probably be replacing this pack with a smaller frameless pack.
Sorry for the long-winded setup, but I thought it was necessary context to my questions. First, how much insulation will a frameless pack have? My current pack has a very thick piece of non-removable foam over a plastic framesheet which provides good insulation and cushioning. It doesn't seem like a frameless would provide much of either.
Secondly, what do you do when it rains? When I used this system last year it never rained on me before I made camp. I use a rain jacket, not a poncho, so after hiking in the rain my pack would be quite wet on the suspension part that sits against my back.
It seems like a lot of people on this forum use their packs like this and would have experienced these problems at some point. Hopefully there is something obvious I'm missing here!
I would really appreciate any wisdom you can share with me on this.
