3.5 R-Value Mummy Sleeping Pad

I sleep best on 4" inflatable on longer trips, the lower inflatables were not supportive enough for my spine, even though were slightly lighter. So, I do consider to carry my slightly over 2 pounds inflatable, maybe can find another that is slightly below at that hight but my ultralight one at R7 value at 3.5inches is not nearly as comfy. It is the way it is made I think. If you consider comfort, think of how many nights in a row you sleep without a back pain on the foam vs inflatable. The inflatable comes at different shapes, lights, etc. It matters which type and everyone likes different one. Can you set up a inflatable at home and sleep on it few nights in a row? Do same with a foam. See which one doesn't give you a back pain and you wake up rested. As someone said - if foam is your best friend, replace it for a new one at that point. Enjoy your hike!

Naturehike sells an inflatable one that has a smaller size that fits you good, I have it and its really good

My nature hike didn't even last one night, for what my anecdote is worth.

8.8R value is fake, Naturehike pads are pretty light and comfortable but are nowhere near pads like thermarest, Exped or STS. This is not possible for this kind of design and lightness to be so warm.

Nature hike hands down. They're a great brand
