How does swapping to a Therm-a-Rest NeoAir XLite affect perceived pack weight on long treks?

I swapped my old Therm-a-Rest ProLite for the NeoAir XLite on a 5‑day loop in the White Mountains. The XLite adds about 200 g to the pack, but the hike felt lighter. The rigid foam was a constant reminder of mass; the XLite's low‑profile chambers let the pack settle closer to my center of gravity. That shift in load distribution made each step feel less like I was dragging a burden and more like I was carrying a presence.

It’s odd how a 0.4 lb difference can alter the subjective weight of the whole journey. The gear isn’t just equipment; it becomes a metaphor for the mental load we bring. When the pack sits evenly on the hips, the mind is freer to notice the trail, not the load. Maybe that’s the real value of lighter gear – it quiets the internal dialogue about “how much I’m carrying.”

No major changes to the rest of my gear list, just the pad. If anyone’s tried a similar swap and felt the opposite, I’m curious why.
