Therm-a-Rest
The sleeping-pad brand that made the self-inflating mattress, then kept shrinking it.
Therm-a-Rest (part of Cascade Designs, based in Seattle) invented the self-inflating sleeping pad in 1972 and has spent the decades since making the same idea lighter and warmer. The NeoAir line is the default ultralight pad most backpackers compare everything else against.
Our take
The warmth-to-weight ratio is class-leading; the tradeoff is fragility, and every tester who has owned one has punctured one.
