What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Therm-a-Rest NeoAir XLite NXT
Three whitelisted testers (CleverHiker, Switchback Travel, GearJunkie) field-tested the NeoAir XLite NXT and rate it a top ultralight three-season pad: 4.5 R-value at ~13 oz, highly packable (about a 1L Nalgene), and far quieter than the crinkly older XLite. All three flag the premium price. CleverHiker and GearJunkie also knock the pump sack; Switchback flags stiff, slippery baffles with slide-off and temperature-shift deflation. (3 sourced reviews, 3 lab-tested.)
Praised: Excellent warmth-to-weight ratio (4.5 R-value at ~13 oz); Much quieter than the previous crinkly XLite; Highly packable / compact (about a 1L Nalgene).
Flagged: Expensive / premium price; Pump sack mediocre — bulky and not the easiest to use; Stiff, slippery baffles; can slide off; temp-shift deflation.
