The Klymit Insulated Double V takes the two-person Double V shape and adds Klymalite synthetic insulation between the V-chambers. The ASTM-rated R-value of 1.9 moves it out of pure summer territory into shoulder-season use, where an uninsulated pad would leave you feeling the cold ground. At 119 cm wide it comfortably fits two people side by side, and the 7.6 cm thickness gives a solid buffer over uneven ground.
That added warmth comes with a weight penalty: at 1497 g and packing to 30×18 cm, this is a car-camping or base-camp pad rather than something you'd carry on a long trek. It ships with a stuff sack only — no pump sack or repair kit — so inflation is by mouth. It suits couples spending multiple nights in one spot who want real insulation between themselves and the ground without managing two separate pads.
