    I'm laying on this pad now actually, super comfortable, warm, and when placed inside your sleeping bag even warmer, it's insane how well this fits your body, 100% would recommend and buy again
  • Not sure about the cut out design
    Verified Buyer Reviewed by Sean from Indiana on Wednesday, February 10, 2016
    This is my second Klymit sleeping pad. The other one I have is very comfortable and packs small. With this design and the cut outs in particular I am afraid of the durability of the product. The cutouts create lots of sharp angles that seem to get caught up when folding and rolling. This pad also have an additional inflation nozzle and a rubber bulb to inflate. This is one more protrusion and my forearm got to tired pumping the bulb and I gave up and blew it up with my mouth in no time. i don't understand why a mat that is specifically designed to reduce the weight as much as possible would include this superfluous bulb and nozzle. I will not be packing the bulb and hence will never used the additional connection point. I think I would have been better off getting another of the standard Klymit V design which I love.

  • Lousy Pad
    Verified Buyer Reviewed by Lost Dutchman from Superstition Mountains on Thursday, December 3, 2015
    Wider? More supportive? Unique cutout design? I was taken it by this hype! This pad stinks. It is totally uncomfortable and did not keep me off the ground. The pump was a joke. After pumping it up and suffering while I laid on it, I deflated it and tried to pack it into the pack size advertised. It was a frustrating nightmare. I can't imagine trying to rely on this piece of.....useless equipment in the backcountry. This one went right back.
  • This has been my mainstay for 2 years
    Reviewed by Cavebird from Gainesville, GA on Wednesday, November 18, 2015
    The only time I have been cold is when had to sleep on the snow, but I slept. I did have to return it for a leak at the high pressure pump port, and it was returned repaired and with caps to stop any leakage. I do tend to pump it up to a higher pressure to keep my 215 lb. 6'3" side sleeping body off the ground. Only take 4 breaths to get it primarily inflated. I have used it a lot, and still like how small it gets for my pack, and the weight/comfort ratio is great.

Question & Answer

  • “1. Does this pad include a pump, if so is it included in the total weight listed?
    2. Is this pad meant to be used inside the sleeping bag?
    3. Does this pad have an R value rating?”
    Asked by Rich B from Connecticut on 3/18/2014 3:32:16 AM
    • 1, There is a small pump. You blow up the pad with your mouth 95% of the way and then the last 5% with the very small pump. It's not really a pump just a hand-held rubber ball thing that attaches to the mattress - it weighs , im guessing - less than one half of an oz.

      2. No, meant to be under the bag

      3. Did not see R factor listed on packaging material. keeps you a few inches off the earth so some insulation value but, not reflective or any 'fancy' padding.

      This is VERY comfortable to sleep on IF you sleep on your back. If you are a 'side-sleeper' I don't think this would work well because of how the 'segments' of material are configured.

  • “what is the thickness of this pad”
    Asked by smokeatet from Oklahoma on 1/24/2014 2:23:45 PM
    • It is 1.5" thick. According to the product specs above: •Dimensions (LxWxH): 78 x 25 x 1.5"
      Answered on 1/27/2014 10:32:03 AM by Product Specialist from Sierra Trading Post
    • The specs say 1.5" but really that's misleading. It's 1.5" at the pillow section, but the rest is quite thin, about 1"
