I have been looking at other offerings from Pacific Outdoors, Vaude, Exped, Trangoworld, Big Agnes (kindly lent to me by Maz whose blog The Journeyman Traveler is well worth a read), Kooka Bay and others for quite some time. I have given them all the 3rd degree, read lots of your excellent reviews and now i have decided on what i want.
Well not just decided but ordered and delivered.
Eventually i went for the Exped Synmat UL 7. It was touch and go between this and the Exped Down Mat, that Robin at Blogpackinglight had kindly suggested to me, but all round the UL7 was my best choice.
I bought it from RoughGear for the Princely sum of £70 for the M size which is 1830mm long x 520mm wide and 70mm thick. The mat has vertical tubes which i have found to be much more comfortable than the Neo Air's sideways tubes. The 2 outer tubes are slightly larger diameter than the 6 inner tubes and UL7 also has synthetic microfibre insulation that has been laminated to both top and bottom of the tubes and the R value is 3.1.
Weight 460gr, that's 200gr more than my small Neo-Air. I saved 100gr on the Creon Lite Rucksack so i am only 100gr on the wrong side at this moment in time, although i have now got the comfort of a full length mat.
Packed, it is about the same size as a 1L water bottle.
Exped Synmat UL7 with Exped pillow attached.The quality of Exped equipment i find to be second to none. You don't go wrong buying Exped.
The valves, of which there are 2, are flat with the mat and work superbly well and very reliable. The warranty is 2 years.
You can buy a separate lightweight pump for all Exped valved kit that eliminates moisture from your breath entering the tubes.
Now i just need to get out and try it properly. More to follow.
