Our Verdict

Lightweight for two! This double pad barely sneaks into the camping mattress category; it's light enough for short backpacking trips if snuggling is a bigger priority than miles covering lots of miles in a day. As we expected, this pad's light weight and packability sacrifice comfort, but this is one of the more versatile mats we tested. The Exped MegaMat Duo can just go car camping and only fits in a giant tent, while the Insulated Double V can go far from the car, fit in a suitcase, or come out of storage for an overnight guest.

This Klymit Double mat is less expensive and lighter than most of the single mattresses in this review; however, it is also one of the least comfortable. The other double mat, the huge Exped MegaMat Duo is super comfy, but it packs away huge, and can only be used in car camping situations with a huge tent. The Double V is a much more versatile mat that will fit in your backpack or your luggage.

Performance Comparison



Comfort


Compared to the average backpacking sleeping pad, the Insulated Double V is a very comfortable mat, but beside a plush glamping mattress like the Alps Mountaineering Outback or our Editors' Choice, the Exped MegaMat. While the V pattern is excellent for keeping the pad light and warm, it's ridges and rails aren't as comfortable as flat, baffle-less foam pads. The Exped MegaMat Duo is our Top Pick for Comfort for Two, but the Double V fits in a backpack and can go many places the Megamat it just too big to go.

With plenty of room for two  this Mattress features V shape chambers that increase thermal efficiency as well as making sure you don't feel it when your partner rolls around.

Ease of Use


This pad inflates by connecting its stuff sack to the inflation valve, opening the roll top closure, blowing air in, rolling the bag shut and pushing air into the pad. It sounds like a pain, but it's not bad at all, and our testers found they could actually move air into the pad without blowing at all, merely opening the top of the stuff sack seemed to fill it with an adequate amount of air.

This mat has a one-way valve for inflation and another for quick deflation.

The stuff sack pump allows you to inflate this pad to maximum firmness. We just pushed on the bag until the pressure blew it off the valve, and then the one-way valve kept any air from escaping. Deflation is as easy as opening the deflate valve and opening the inflation valve a keeping it open with the pull tap. Roll it up tight and stick back in the pack, or if you're feeling lazy or in a hurry, the stuff sack is generously sized, and it's easy to get the mat in if it's not rolled super tightly.

The V shape chambers are a great strategy for keeping this mat warm and lightweight but aren't nearly as comfy as the baffle-less foam mats in our review.

Warmth


An R-value of 4.4 makes the Double V appropriate for year-round use in the lower 48, and plenty of warmth to help the reluctant camper get outside, and sprawl out beside their sweetie underneath the stars. Though thin, this mat is insulated with Klymit's proprietary synthetic insulation and the chambers created by the V weld patterning limit air circulation, so the Double V doesn't suffer from circulating cold air like the Nemo Nomad and the Soundasleep Camping Series. Additional warmth comes from the snuggle factor you can only get on a double pad. The Exped MegaMat Duo is warmer, but you're not likely to want to lug that nearly 10 pound behemoth very far in the woods.

This mat uses its own stuff sack as an inflation pump. Klymit recommends blowing into the bag to inflate  then rolling the top up and pushing air into the mat. Our testers found that they could get plenty of air in the bag without using a single breath.

Versatility


At 3.6 pounds, the Insulated Double V is about the same weight as two (kinda heavy) backpacking sleeping pads, and it's the lightest pad in this review, even lighter than the Nemo Nomad, which is only sized for one. The Double V is warmer than the Nomad, and more packable than any other mats in the review, despite being sized for two.

The generously sized stuff sack makes for easy packing  but with a little extra effort  the pad will pack down even smaller.

Packed Size


The Double V packs down to a svelte 7X12", a little larger than the Nemo Nomad, but not by much, especially considering it's a pad for two. It's small enough for a carry-on and easily fits in larger luggage, not something we can say about foam core pads like the Exped MegaMat and the Therm-a-Rest Dreamtime.

A double-wide camping mattress can make for a more fun  cuddlier camping experience.

Best Applications


This model is light enough to go on short backpacking trips when you and your S.O. want to snuggle without pushing that pads apart and ending up on the ground. Make sure you've got sleeping bags with opposite zippers so the can zip together. For warmer weather, you might want to pair your down blanket with a sheet, since this mat has a sticky, plastic feel.

Value


One hundred and sixty dollars for this lightweight cuddle space is an awesome deal considering its versatility and the fact that it's for two. That's $80 per person, compared to the inexpensive Soundasleep Camping Series that goes for $120 and only fits one.

Conclusion


This Klymit Double V is way more usable than we expected. A bicycle built for two isn't the most practical way to bike around, but it sure can be fun. The same can be said for the double pad. Sure it's a little heavy, but it's worth the smiles, and while a little novel, this pad is lightweight and warm enough that it's likely to get used more than you'd think.
