Ok, so those with back problems, or general sh** sleep on the mountain, what have you done to increase comfort and improve your quality of sleep?

The old thermarest just isnt cutting it for me anymore. Wake up all stiff and sore. Curious what ex thermarest users have moved onto. Thanks!!

My basecamp setup is quite comfy with generous foam and a cot, but obviously, it's not practical for a hike-in hunt.
