Does anyone have any first hand experience with these types of sleeping mats? The full length one is 258g, and there is an even lighter 3/4 length one at 155g. They look pretty funky, and the description of your down sleeping bag poofing out the holes and not being compressed sounds good in theory....

There are several You Tube videos as well, one is featured in the link above

In the near future I wll be upgrading my sleeping mats - I'd like to get a lightweight warmer season one (considering Xped simlight/synmat7 or prolight or a neoair), as well as a winter one (looking at Xped downmats 7 or 9). I am still researching, and reading comments here.
I was wondering about this kinda odd looking one!

I have heard/read of people finding they dont fit. Ie the padding for their shoulder/hips/ankles doesnt line up. So therefore it is a try before you buy I would expect.

And I have had friends who put holes in their after 1/2 weeks typical use ...

For me, after a bad experience with Outdoor Equipment pads, I do/would only buy thermarest now. Sure its more expensive but you dont hear of people getting holes or having problems with normal use.

OO wow - I found this fantastic chart!

I bought one of another member here, spent a couple of nights on it. Yep, you need to be the right size abt 5'10" plus seems ok... I think the seller was too short.
If they work for you then the good points are that they are tiny packed, V light and they seem to hold pressure much better that T-rest etc. I'm not sure abt punctures. The material is pretty thick, i'd imagine thicker than neo fabric?

I have used one for 3 days on Kosci - very nice.
Would have to line up with the body parts though.
Even with a bit of tossing and turning - it supports very well, as the air has nowhere else to go.
Very small and light too.

Exped basic ul7 seems pretty good for a summer mat. Under 400gms and only 80 bucks. And u don't have to worry about falling in the gaps

I think the whole point is falling through the gaps. Instead of being squashed flat (and thus ineffective), the insulation in your sleeping bag holds its loft (and warmth) beneath you in the vacant spaces of the Klymit.

That said, I am still lusting after the Synmat UL7.

No good if ur shoulders or hips fall thru the gaps though

The newer synmats look ok, we didn't have a good run with exped (as is well available here in a search) but same with t/rest.. inflatable mats seem pretty much a 'consumable'. Some seem to have a good run but i'd imagine from an engineering point of view they are All doomed to fail.

There is a ytube including an idea of the klymit theory (as eggs says,the small volume means the air has nowhere to go.. they don't loose loft like your synmat does (or will..)). The other attributes aren't easy to disgard either, the thing really is Tiny, featherlight, nothing in your pack. I suppose the down lofts under the bag, the shell material gets tight under there..they don't feel cold in the gaps..

But yes, either an acquired taste, works or doesn't. Some people just wont get along with this one.

PS.. They would be a horror on the knees if that is the part that misses out..
