Well, in the interest of not completely trashing their products, I will not launch off into a complete angry tirade. However, this last trip to the desert in Peru has proved to me beyond a shadow of doubt that Klymit products have fallen way down in the quality control and reliability department.
In the past year, I have had three different Klymit pads (2 Inertia XLs and 1 Insulated Static-V) fail miserably. There are no discernable holes in any of them. I used a ground cloth every time. I suspect that the valve system on them is substandard and also likely the seam welds. I am sending all three back to the company, expecting a full refund for each. A colleague of mine also had an Inertia XL fail as well, during our recent trip to South Africa. If they had been heavily used or abused, then maybe I could give them a pass....but each of these were barely used. In fact, this last one in Peru had been downright "babied". This was only its second outing. As far as I'm concerned, that is completely unsatisfactory. When you must be able to rely on your equipment in austere environs, things like a failed sleeping pad can become very important....especially in a survival situation.
Unquestionably, part of these failures is due to them being produced out of Taiwanese sweat shops. These are not cheap pads, price-wise. They are farily expensive. Not Neo-Air expensive, but more than several other models out there. I used to like Klymit pads a lot...but recent experiences have caused me to think their QC has gone way downhill.
Just wanted to let folks on the forum know about these failures. Thank God that HPG can still be counted among the American companies that produce top-shelf kit that is truly backcountry worthy.
