Similarities

There are quite a few similarities between the Klymit Double V Insulated and Uninsulated Sleeping Pads, but the 2 most important ones are:

  1. Comfort; and
  2. Quality.

Comfort

Both Klymit Double Vs have similar dimensions (length x width) of about 74 by 47 inches. (The Klymit Uninsulated Double V was slightly smaller by an inch, but there’s always a small margin of error during manufacturing.)

This is a picture of me putting the Klymit Insulated Double V on top of the Klymit Uninsulated Double V to compare dimensions. You can see that both sizings are very similar.

Both Klymit Double Vs have a thickness of 2.5 inches, which was fairly comfortable, although I could sometimes feel the ground when tossing and turning in bed.

Both come complete with V-shaped air chambers across the entire sleeping pad and side rails that provide pretty decent edge support. Bouncing is very minimal for both.

Quality

Both Klymit Double Vs are made of 75D polyester, top and bottom, both have separate FlatValves for Inflation and Deflation, and air retention is equally great for both.

Both stuff sacks double as pumps, which can inflate the Double Vs very quickly even without air flow (like inside a tent, just like the picture below), and even without having to use your breath.

Differences

There are also quite a few differences between both Klymit Double Vs, but these are the most important factors I will be going through:

  1. Portability;
  2. Insulation;
  3. Inflation;
  4. Deflation; and
  5. Pack Up.

Portability

The Blue Klymit Uninsulated Double V weighs 43.4 ounces or 2.7 pounds for both the Double V and the stuff sack.

The Red Klymit Insulated Double V is slightly heavier, and weighs weighs 57.2 ounces or 3.6 pounds, which is about 30% more.

The Blue Uninsulated Double V has a packed size of about 11 by 7 by 5 inches, while the Red Insulated Double V has a packed size of about 12 by 7.5 by 7 inches, which is about 60% bigger.

Insulation

This is because the Klymit Insulated Double V has more insulation and a higher R-value of 4.4, while the Uninsulated Double V has minimal insulation and a much lower R-value of 1.3.

The Klymit Double V Insulated Sleeping Pad has an R-value of 4.4.
The Klymit Double V Insulated Sleeping Pad has an R-value of 4.4.

Inflation

Without Airflow

When I inflated both Klymit Double Vs without air flow, the bags of air tend to be slightly smaller. For the Blue Uninsulated Double V, it takes around 17 bags of air to fill it up, which is around 2 minutes and 15 seconds.

This is a picture of me sticking my entire arm into the stuff sack of the Klymit Double V Uninsulated Sleeping Pad inside a tent where there’s no airflow.

Because the stuff sack of the Red Insulated Double V is slightly bigger, it takes only around 13 bags of air to fill it up, which takes about 1 minute and 45 seconds.

With Airflow

When there’s moving air flow, the bags of air are slightly bigger, and it takes me 14 bags or 1 minute and 45 seconds to fill the Uninsulated Double V.

It takes me around 11 bags of air or 1 and a half minutes to fill the Insulated Double V.

Deflation

I deflate both Klymit Double Vs the same way, by opening both valves, folding them in half, length-wise, 2 times, and rolling it up to squeeze the air out.

It takes me about 1 minute to deflate the Blue Uninsulated Double V, and about 1 minute and 15 seconds to deflate the Red Insulated Double V.

Pack Up

I also pack both Klymit Double Vs the same way, by folding them in half, length-wise, 3 times, and then rolling them up as tightly as possible.

This is a picture of me rolling up the Klymit Double V Uninsulated Sleeping Pad to pack back into its stuff sack.

Then, I fit them back into the stuff sack and compact the  top down as much as possible before buckling it up.

This usually takes me about 2 minutes for the Uninsulated Double V and 3 and a half minutes for the Insulated Double V.

Recommendation

The Red Klymit Double V is more insulated and thicker, so it has a slightly larger stuff sack, and inflation takes 3-4 bags less, which is about 30 seconds less.

However, the Red Insulated Double V also takes about 1 and a half minutes more to pack back into the stuff sack, because air gets trapped in the baffles more than the Uninsulated version, so it’s harder to deflate.

The Red Insulated Double V also weighs almost a pound more than the Blue Uninsulated Double V, and has a 60% bigger packed size.

Here’s a table showing you the differences:

2P Air PadInsulated (Red)Uninsulated (Blue)
R-Value4.41.3
Inflation11-13 bags / 1.5 mins14-17 bags / 2 mins
Deflation4.75 mins3.25 mins
Total Weight3.6 pounds2.7 pounds
Packed Size12 x 7.5 x 7 inches11 x 7 x 5 inches

Overall, I really enjoyed using both Klymit Double Vs over the past year, and they’re both very versatile, because I could take them on shorter backpacking trips, camping, traveling, and they could fit into all 2-person tents, even ones with lower peak heights.

The Red Insulated Double V is slightly more versatile though, because it can be used for 3-season camping.

But the Blue Uninsulated Double V is more portable.

So, if you don’t need the insulation of the Red Insulated Double V, I recommend the Blue Uninsulated one, so you don’t have to lug around more weight.
