anyone got one of these? I fancy the insulated version for winter. Looking for best deal
I have the Klymit insulated Static V luxe X large - a serious compromise on weight compared to my Neoair.
I haven't been out with it yet, hopefully next week but it is by far the most comfortable sleep mat I have laid on in my 'front room'
I like my static v2 uninsulated ground mat. At nearly 1 kg for the insulated though it doesnt appeal.
My standard insulated Static V is 770g.
After 2 years use, My green V2 keeps leaking air on the edges of various of the glued "dots" at the end of each glued seam. Fix one, after a night or 3 on the next trip, another one or 2 go.
Gave up and bought a neoair xlite sv in July After about 30 nights use, that, a glued seam/baffle popped. Currently away to supplier.
Originally had a POE mat, then Exped Synmat7, exped UL 7, also leaked on seams (not punctures) or blew out baffles/seams.
These inflatable mats just don't seem durable.
I think you've seen the weight of the Insulated Static V Luxe, which is 30" wide.
Unfortunately I'm a lot wider than most mats. For a good night's sleep I'll carry the extra weight.
$100 on Massdrop (insulated version) but factor in postage and customs.
The weight of the insulated hammock v is 900 and something.
What sort of temperature range is it suitable for?
(I'm rubbish at R values)
Seems heavy compared to an underquilt.
This fella doesn't rate it for cold weather,
Sorry to be a pad-hater, but a cheaper, lighter and more effective option is two CDTs made into a Gemini underquilt. I've used that down to -6°C.
Ah, ok. I thought you were referring to the insulated version of the Static V2.
@Gadget On the ground, the insulated Static V pads are fine for winter (I've only used them in temperatures down to just under -10) with a thin ccf mat on top. We use them with a quilt and perhaps it might be different with a sleeping bag, but I think quite a bit of heat escapes through the channels without the ccf mat.

That's what I don't understand about those Klymit mats. If the insulation is below the air so that the air gets heated by the body then all the gaps between the channels must be cold. Giving with one hand and taking away with the other. And then doesn't the CCF on top mean that your bodies are not heating the air in the mat. So how does it work?
The CCF layer is about reducing the temperature differential between the cold and warm surface that the air is trapped in. The smaller the differential, the less convection occurs.
It's the convection of the air inside those channels that takes heat away from the warm surface and either conducts, or radiates it to the cold ground. Air is a bad conductor, but removes heat by convection quite well.
Put simply ,that air doesn't get warmed as much if a supplemental mat is used, so moves less and therefore doesn't remove as much heat energy.
Placing the CCF mat under, or over an airmat makes little difference, as both methods reduce convection. It's more down to usabilty and convenience than pure insulating properties
Conduction in this system is low, and the only other way the system loses heat to the ground is radiation.... that's why lots of sensible folk use a reflective CCF mat underneath.
but what about the gaps between the channels on a Klymit mat?
(it's possible that I haven't understood)
Believe this is to trap air. I Have had the https://www.klymit.com/insulated-static-v-lite-sleeping-pad.html down to minus 2 in a single Skin tent. This mat feels like my bed really warm and cosy.
