This pad is perfection. Light weight, 2 inches thick, no slip bottom, comes with stuff sack and repair kit, reasonable priced.


  • Light weight
  • Extremely comfortable
  • Tough material
  • No slip bottom
  • Comes with extras
  • Packs down small
  • THICK!!!!!

This pad is perfection. The material feels rugged and durable. It is a full 2 inches thick and still keeps its weight to about 1 pound. I purchased the 3/4 pad, which was a gamble because I've only ever owned full length pads, but there was no awkward transition to the smaller pad.

The "rubberized" bottom is great, once it's down it never moves. When I roll on my side I never "bottom out" on the tent floor, this is the first time i could describe a pad as plush it's so thick. Another bonus is the fact that it come with a stuff sack and a repair kit.

The first night I used it it was one of the first times I "passed out" on a hike just from comfort and not exhaustion. Should be the new standard for pads. Plus the old school logo and color are a nice touch.

Great pad that I would recommend to those who are not willing to compromise a good night's sleep.


  • Comfortable
  • Great design
  • Stuff sack/repair kit included


  • Could be considered heavy

Sleep is incredibly important to me. With that being said, I was willing add a few ounces to the weight of my pad for extra comfort. For me, it was a good choice. I am 6'1" and 185 lbs and side sleeping proves to be no problem at all on this thing. In fact every position is comfortable on this pad and one should never feel bones (hips) digging into the hard ground. 

The warmth factor is good enough for me. I am a hot sleeper so I the R rating was never my chief concern when purchasing.

I like the throwback design and included stuff sack and repair kit. I feel like those extras should always be included but unfortunately they are not. The glow-in-the dark valve is another cool feature although necessary in my opinion.

Great pad. Don't need the full length, but it's good to have when you are barefoot at night.

Wish it had concealed clips to fix it to your sleeping bag, as I often slide off the pad.
