Test scorecard
The Klymit Double V Uninsulated is high quality, easy to use (it inflates even without airflow!), and the lightest, most portable camping pad for couples that I own. The only downside is that it can’t handle the off-season or winter — it’s uninsulated.
- High quality
- Easy to use
- Portable
- Versatile
- Not for off-season or winter camping

In the Box
I bought my Double V Uninsulated from Amazon. Here’s what came in the box:
- The Klymit Double V Uninsulated, inside its stuff sack
- Instructions
- A patch kit
Thickness
- Thickness 2.5in
- Loft Air
Inflated to firm, my body never touched the ground on my back, stomach or side.
But I could always feel the ground when I leaned on an elbow or knee, or just sat down. Sometimes when I tossed and turned, too.
Dimensions
- Length 74.0in
- Width 46.0in
That’s nowhere near a Queen or even a Full, and only slightly wider than two regular sleeping pads side by side.
Not the most spacious, but I found it comfortable enough for the two of us.
Air Chambers
V-shaped baffles run across the whole pad. They give my body a lot of support and contour to it.
If you’re used to flat, cushy self-inflating foam mattresses like I am, the surface takes some getting used to. After a few days it felt decently comfortable.
Edge Support
The side rails won’t stop you rolling off, but the edge support is better than on the higher-profile 2-person air mattresses I own.
Bounciness
The left and right chambers aren’t completely separate, but they still cut enough air movement to keep bouncing minimal when someone shares the pad.
Noise
The surface fabric is a little louder than my other 2-person air and self-inflating mattresses. At least it doesn’t sound like a bag of chips.
Valves
- Valves 2 FlatValvesone at each end of the head
- Inflate valve 1-way, only lets air in
- Deflate valve Simple 2-way opening
Both sit flush with the surface, and both are labelled.
They’re low profile and I love having a separate valve for each job. The flaps feel thick and rugged, and I had no air leaks in the weeks I used it.
Inflation
Pull the flap off the Inflate valve, then push the bottom of the stuff sack onto it. It pops into place, and the sack becomes a pump.
With no airflow at all — inside a tent, say — I stick my whole arm into the sack and move it up and down to even out the wrinkles. That alone fills it, which is quite amazing.
If there’s wind, just face the opening into it. Then fold the top down 2 or 3 times and press the air in with your free hand.
| Conditions | Bags of air | Time |
|---|---|---|
| No airflow | 17 | 2 min 15 s |
| Moving air or wind | 14 | 1 min 45 s |
Once no more air goes in, pull the sack off and put the flap back on.
If it ends up too firm, open the Inflate valve again and press the built-in flap gently to let a little air out.
Deflation & Pack Away
Pull the flaps off both valves. Fold the pad in half length-wise twice, then roll it up from the end without the valves, as tightly as you can.
If air stays trapped in the last few rolls, press gently on both valves to clear them.
To pack it away, fold it in half length-wise three times, roll it tight again, then push it to the bottom of the stuff sack and roll the top down.
If air gets stuck as you roll the top down, lift the whole sack off the ground and it escapes through the hole at the bottom.
- Deflating and rolling up 1 min
- Folding and packing away 2 min 15 s
- Total 3 min 15 s
Stuff Sack
The blue stuff sack has a roll-top, so I can compact it down as much as I need to.
It feels like the same material as the pad, and it held up to a lot of pressure as a pump without complaining.
The buckle at the top doubles as a carry handle.
My one complaint is the opening. It’s small, so if the pad isn’t deflated enough it won’t go back in.
Portability
- Packed size 11.0 x 7.0 x 5.0in
- Total weight 2.7lbs (43.4oz)
- Pad 40.3oz
- Stuff sack 3.1oz
- Ease of carry Buckle handle on the stuff sack
It’s a touch too heavy to count as ultralight, but fine for shorter backpacking trips if you can spare the weight and the space.
Insulation
- R-value 1.3
- Seasons Summer only
Tent Sizing
In my Coleman 2-Person Sundome, it doesn’t fill the whole floor, so there’s room for gear at the sides.
It’s low enough that I still had plenty of room to sit up and crouch. I could inflate it inside the tent, or inflate it outside and squeeze it in.
In my Coleman 4-Person Dome I could fit both my Double Vs side by side, with space left over for gear and enough headroom to almost stand up.
Materials & Air Retention
- Material 75D polyestertop and bottom
That’s on the thicker side for a sleeping pad and it feels durable. Top and bottom feel identical in thickness, so I think the whole pad is 75D.
The seams are good quality and air retention is excellent. Two of us (300+ pounds together) slept on it three nights in a row without topping up any air.
I’ve had it a year now with no leaks at all.
Pros, Cons, Recommendations
Now, what are the pros and cons, and would I recommend the Klymit Double V Uninsulated?
High quality
Everything feels well made, from the pad and its separate valves to the stuff sack, and a year in there are still no leaks.
Easy to use
It inflates in about 2 minutes, deflates and packs up in 3 minutes, and I can make micro adjustments if it ends up too firm.
The most portable pad I own
2.7lbs and 11.0 x 7.0 x 5.0in packed — barely bigger than a 32-ounce Nalgene bottle, and my most portable 2-person sleeping pad by a mile.
Very versatile
It’s nicely sized and low profile, so it fits every 2-person tent I own, even the short ones. You get:
- Camping, backpacking and traveling
- Inflating with or without airflow, because the stuff sack doubles as a pump
- Micro-adjustable firmness through the Inflate valve
Summer only
At R 1.3 this one is strictly a warm-weather pad. The insulated version is the one to get for 3-season use.
The surface takes getting used to
The V-shaped chambers aren’t as smooth as a flat self-inflating pad, and it took me a few days to adjust. Plenty of other reviews call it super comfortable, so this one may just be me.
Overall recommendation
The pros here greatly outweigh the cons. Get the Klymit Double V Uninsulated if you want one pad for everything — backpacking, camping, traveling, and any 2-person tent. It’s low profile enough not to eat into your livable space, even in tents with a low peak height.
