I'm 60 and get pretty sore trying to sleep on my side with a thin pad eg .75 thick Thermarest. I currently am very happy with Big Agnes mummy shape 2.5" inflatable, can easily sleep on side, not hard to inflate/deflate, so far durable in the Grand Canyon, Wonderland Trl etc. But, I'm wondering if I would get used to a Thermarest Z-Lite, I like the compact foldup design, and would be near indestructible. Opinions about getting used to sleeping on these typical thin pads? I'm wondering if I would rather have a Z-Lite on the AT after a week getting used to it. Thanks
