Familiarity: I've put it through the wringer
I've had 2 of these for 5 years and they've taken plenty of abuse. Not so great for sleeping on snow or for side sleepers and is bulky strapped to the outside of your pack. And those were the main reasons I finally upgraded to an insulated inflatable that packs down to about 5"x9". But if you want something cheap, durable, easy to take care of, has multiple uses and bulk is not an issue, everyone will tell you the Thermarests are the way to go.
