I've heard it as basically: anything that seperates you from the ground.

That theory worked for me for everything

Motorcycle gear

Tires

Boots

Climbing gear

And then I got into hammocking, and nothing seems to beat my first, a Bear Butt I got for 50$. Seems the more expensive they get, they lose out on just being big nice expansive hammocks with silky smooth material. So not a hard rule I guess!
