Big Agnes Insulated Double V Sleeping Mat

Jump to: Our Verdict / Features / Specifications

The Insulated Double V is super comfortable double sleeping mat that gives you both a lot more protection from the cold, keeping you both warm through the night. The storage bag/pump sack is useful and makes inflating the mat much easier.

Klymit says

Cozy up in the cold with your partner and Klymalite™ lofted synthetic insulation. Cold nights are the perfect excuse to cuddle – now you can share the same sleeping pad instead of fighting to keep two pads together. Like all our Klymalite™ insulated pads, the Insulated Double V™ isolates warmer air to the top of the pad, while the V-Chamber design limits the movement of air for optimal thermal performance. The Insulated Double V comes with a convenient, pump-integrated stuff sack for easy, rapid inflation.

Our Verdict

Klymit’s Insulated Double V Sleeping Mat is a great option for anyone after a double sleeping mat. It retains a lot of the features of the original Static V in that it is still a lightweight sleeping mat using body mapping technology at a really competitive price. It features the v-chamber design which limits air movement and heat loss while offering a uniquely ergonomic body map which is optimzed for performance and comfort.

This double version comes in a handy storage bag which doubles as a pump sack so it saves a lot of time and energy wherever you are. Like some of the newer Klymit sleeping mats it features an easy-to-use valve that makes inflating and deflating even easier. You also get a bonus patch kit for making field repairs.

This mat is surprisingly comfortable and great for camping, the R-Value on this insulated version is much greater than the non-insulated version so if you do feel the cold when the temperatures drop the extra weight here is worth it for the warmth it delivers.

ASTM R-Value:

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.

In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
