My experience varies. I'll share:
I sleep in a hammock, which means my head is slightly raised and my feet as well. Because of that, call me crazy, I just don't use a pillow; I use the top of my pad.
I was pretty over having cold feet from them hanging off the edge of the Neo-Air All-Season, but I can't fit my backpack in there with the long pad. After my post, I was inspired by someone's comment about REI's return policy and decided to put their satisfaction guarantee to the test. After my next trip, I'll be doing the following exchange:
NeoAir Regular All-Season Sleeping Pad: 19oz, 20in x 72in (140$)
Thermarest Z Lite Sol: 14oz, 20in x 72in (44$)
Thermarest NeoAir X-lite Small: 8oz, 20in x 47in (130$)
+3oz in weight, but I feel like my relative comfort will increase. It also gives me the option to shed tons of weight in the summer by bringing just the NeoAir X-lite Small if I'm bike touring. The All-season was overkill in the middle of August (though, not particularly uncomfortable at all)
Additionally, my pad is very safe in my hammock but on the ground, I'm always nervous about punctures. Blowing them up also takes time. If I went on a thru-hike (and I plan to), I'd bring just the Z-Lite Sol for a guaranteed good night's sleep and no setup time.
Thanks for the inspiration, mates!
