The Z-Lite is part of Thermarest's "Fast and Light" series of pads, targeted to three season backpackers. According to Therm-a-Rest, "These mattresses are engineered for users who will be carrying their mattress, and consider mobility and packability slightly more important than durability and comfort. Fast & Light mattresses are durable and comfortable, but our Trek and Travel mattresses are slightly more durable and comfortable, with only a minor increase in weight."
You can choose between a short (20x47") or long (20x72") pad - a short pad is lighter but won't insulate your feet. Solve that problem by carrying a piece of industrial strength plastic; use it under the lower part of your bag and it triples as a seat or a dry place to stand while you change clothes on wet ground.
