Klymit Insulated Static V Lite Eco Inflatable Sleeping Pad

Product detailed description

Sustainability and Eco-Friendly Production

The Klymit Static V Lite Eco is made from Bluesign certified fabric (30D Polyester). This means it is made from approved chemical raw materials and manufactured with minimal impact on people and the environment. Above all, this results in a more sustainable production process and is aimed at eco-conscious hikers who strive to contribute to preserving nature for future generations.

Thermal Comfort

Thanks to its synthetic insulation, the Klymit Insulated Static V Lite Eco achieves a thermal resistance rating of R = 4.4, which is more than sufficient for three-season use.

Comfort and Efficiency

Like other Klymit sleeping pads, it uses V-shaped chambers and special, firmer-feeling side chambers that prevent you from sliding off the pad at night. Users who have switched to Klymit from other brands mainly highlight the comfort, the fact that the mat feels significantly wider, and that it inflates with just a few breaths (about 12) given its size. It might seem that the extra effort required to inflate the mat compared to competitors isn’t a big deal, BUT—with every breath you take, you introduce a certain amount of moisture into the mat that you can’t easily get out. The mat becomes heavier and may even start to mold. Half the number of breaths compared to competitors makes a huge difference!

We have also added to our product range inflatable bag with a flat "flip valve" for easier inflation of sleeping pads and to reduce condensation inside the pad when inflating by mouth.

Lightweight and durable material

Compared to the classic version V2, the manufacturer chose a lighter material for the Klymit Insulated Static V Lite Eco, even for the bottom (30D). That shouldn’t be a problem, though, since the mat is designed for camping in cold conditions—it’s hard to puncture it on snow, and in freezing temperatures, few people sleep without a tent, a tarp, or at least Tyvek under them... and besides, the competing Neo Air X-Lite uses the same weight, and no one has had a problem with it over the years.

New valve

In 2019, Klymit introduced a new, patented valve. Unlike the previous version, it is recessed and doesn’t get in the way. The inflation valve is one-way, so air doesn’t escape while you’re inflating it. When you want to deflate the mat, simply press once to rotate the internal “baffle,” and the mat deflates. A pretty simple solution… As for winter use, our experience with inflatable mats (regardless of brand) is that at temperatures around -10 °C and below, you’ll need to supplement it with a thin foam pad. For just two winter trips a year, it’s definitely not worth buying a one-kilogram self-inflating mat and lugging it around all year. It’s better to have a lightweight three-season sleeping pad and supplement it with a thin foam pad or aluminum sheet during occasional extreme outings. With Klymit sleeping pads, you definitely need to place Tyvek or another tarp underneath on the snow to prevent snow from getting between the chambers and causing cold to seep through the seams.

Decent weight

In terms of weight, this version with an insulating layer is only slightly heavier than the uninsulated version Static V Lite Eco, 585 g without the bag, but it takes up significantly more space, so you need to factor that in. However, it’s still half the volume of a comparable self-inflating mat. During testing, I found that it can be packed down to a much smaller volume than the original included stuff sack. The manufacturer assumes you’ll be packing the mat in the morning in freezing cold, likely wearing gloves, so that even a poorly packed mat can be easily stuffed into the stuff sack. As usual, great value for money and more points for Klymit. We recommend placing Tyvek under every inflatable mat, which significantly reduces the risk of punctures.

New Standard and Practical Experience

Since 2021, the manufacturer has also been listing the thermal resistance value measured according to the new ASTM F3340-18 standard on the sleeping pad packaging. This standard aims to unify the measurement method for all sleeping pad manufacturers. According to Klymit, nothing has changed in the design of the sleeping pads, and they are still suitable for cold conditions just as before. We can confirm this from our own experience, as we have spent dozens of nights sleeping on these models in sub-zero temperatures. Based on the measurement results, it is quite clear that under the new standard, sleeping pads with an internal reflective layer—such as Therm-a-Rest pads—will perform best.

In our opinion, Klymit sleeping pads exhibit heat loss in the areas where the internal synthetic insulation is compressed. However, the standard does not account for one major advantage of these sleeping pads. Thanks to the shape of their chambers, the space between the chambers is filled by the sleeping bag’s filling. This creates space for additional insulation. This is not the case with "flat" sleeping pads. In our opinion, Klymit sleeping pads will perform just as well in cold conditions in practice. In laboratory tests where a sleeping bag is not used, they will simply perform worse.

To highlight the sustainability of the ECO line, Klymit, in collaboration with Grow my Tree, planted 600 trees.
