I own three Therma-a-Rest pads (2.5 pounds, my original; 1 pound, four ounces (full size) and a 3/4 body version at 15 ounces) and a Downmat 7 (filled with down and really warm) that comes in at a little over two pounds. Of course, the 3/4 pad would be the first choice for the ultralight backpacker. But the lightness comes with a trade-off: you sacrifice comfort and warmth by having your lower legs and feet hanging off the mat. If the weather is warm, it’s not a problem. But now you don’t have to settle for less comfort to get the advantages of fewer ounces.
I was at REI last week just checking out gear when I came across the Therm-a-Rest NeoAir.
The new NeoAir pad is full size, a couple of inches thick and packs down really small — about the size of a one-liter bottle. It’s worth a look.
Be light. Be safe. Be one with the pack.
