In theory, a two-person sleeping pad is a soft spot to snuggle up with your hiking lover. We used the Klymit Double V to put this theory to the test.
It was about 2 a.m. when my wife had to answer the call of nature. I know this because there was a sudden deflation under my back, which after several hours of comfortable support, was suddenly grazing the rocky earth ever so slightly.
She returned about five minutes later, a fact I know because there was a little bounce action as she crawled back in the tent and the mattress pressure increased. These are the flaws of a two-person sleeping pad.
