When you combine this 59" pad with the shorter torso eggshell pattern pad it works.
The thin pad protects from moisture, dirt, needles, rocks, etc. And, when combined with the torso pad keeps the legs comfortable and insulated.
I wrap mine up with my torso pad and it works great at the top of my pack carried under the hood thing. At about or less than 2 oz. it is worth the weight. Maybe this picture will show what the bundle looks like after it has been used a few times so the shape changes to conform to the packing job:
Here it is attached to my pack (REI UL 45), with the snow scoop from the BPL Gear Shop on the back of the pack and an insulated cup (which embarasses me to myself, but my partner loves it and convinced me to get one from Campmor -- I think its going, I'd rather use a styrofoam cup from Denny's or Burger King or such, if any at all ... although I love the warm sweet coffe or tea or lemon juice after a bit of snow shoeing around this place).
I have tried to velcro the two pads, the 1/8" and the eggshell torso, together so they won't slip on each other at night, but so far haven't found a good glueing agent.
All I can say is for the price and weight this is a 5, plus you get to support the UL people and deal with them.
It also provides options in different heat, weather, and terrain conditions for what I take with me because I can always shift up to the 3/8" version (or there is also now a 1/4" that is newer and which I don't own)if I want the extra padding and insulation value. I have slept on the 3/8" by itself and it works but isn't perfect -- but add the eggshell torso pad and it makes it a luxurious experience, with a good down bag, at about 5.5 oz. for the 3/8" instead of around 2 oz. for the 1/8".
