The short answer

Get the Uninsulated, unless you camp cold.

Both Double Vs share the same ~74 × 47 in bed, 2.5 in thickness and build quality. The Klymit Double V Insulated adds an R-value of 4.4 for 3-season camping, but it weighs almost a pound more and packs about 60% bigger. If you don’t need the insulation, I recommend the Blue Uninsulated one, so you don’t have to lug around more weight. Get the Klymit Double V Uninsulated here.

Which applies to you?

Get this one if…

Get the Double V Uninsulated if…

  • You camp in warm weather, because R-value 1.3 is minimal insulation.
  • You carry your gear: it’s almost a pound lighter and packs ~60% smaller.
  • You want the quicker pack-away, about 1.5 minutes faster.

Get the Double V Insulated if…

  • You camp in colder, 3-season conditions, R-value 4.4.
  • You want the quicker inflation, 3-4 fewer pump bags, about 30 seconds less.
  • The extra pound in your pack doesn’t bother you.

Comfort

Bed size~74 × 47 inMine ran an inch smaller — margin of error~74 × 47 in
Thickness2.5 in2.5 in

Both are fairly comfortable, though I could sometimes feel the ground when tossing and turning. Both have V-shaped air chambers across the whole pad and side rails with pretty decent edge support, and bouncing is very minimal on both.

Insulation

That R-value is what makes the Red Double V Insulated a 3-season pad.

No airflow~17 bags · ~2 min 15 s~13-14 bags · ~1 min 45 s

The Insulated’s slightly bigger stuff sack fills it in fewer bags of air.

Deflation

Deflate time~1 min~1 min 15 sAir gets trapped in the baffles

I deflate both the same way: open both valves, fold in half length-wise twice, and roll the air out.

Pack Up

MeasuredUninsulatedInsulated
Pack-up time~2 min~3.5 min

Packing is the same for both: fold in half length-wise 3 times, roll as tightly as possible, fit into the stuff sack and compact the top down before buckling. The Klymit Double V Uninsulated is the easier of the two to squeeze back in.

My recommendation

Both Double Vs are versatile. I’ve taken them on shorter backpacking trips, camping and traveling over the past year, and they fit into all 2-person tents, even ones with lower peak heights. The Red Klymit Double V Insulated is the more versatile pad, because it can handle 3-season camping, but it packs 60% bigger, deflates slower, and weighs almost a pound more.

If you don’t need the insulation, I recommend the Blue Uninsulated one, so you don’t have to lug around more weight. Get the Klymit Double V Uninsulated here.
