Weighing in at around 460g this camping mattress is perfect for any ultralight hiker or bike packer. It rolls up to approx 200mm long and about as wide as a fist so it's pretty slimline to fit in your pack
I use a schnozzle to inflate my mattress to avoid bacteria build up from your breath. It inflates almost to the size of a lilo. It has separate inflate and deflate 1 way valve system to ensure you don't lose any air
The insulation in the bottom is perfect for reflecting the cold ground ensuring a warm nights sleep. I have used this mat at above 4000 metres whilst camping in Nepal and it was perfect. I have also been camping in snow and have not felt the cold from the ground at all.
This mat is also relatively quiet when you are rolling over. I won't say it's silent but it is better than most of other mats.
We are currently using 2 of these mats as we bike tour the Great Divide MTB Route, and so far they have been robust enough to be used almost everyday for nearly 2 months...pretty good for ultralight gear.
The only problem I have experienced with this mat and I think it is only in the older models is there is a valve in the deflate port. This can make it painful to dump all the air out and get a good roll done with the mat. I have solved the problem by removing the valve. The only time my mat has gone down is when a small piece of fibre has been wedged in the closed deflate valve causing it to weep slowly and result in an uncomfortable nights sleep.
So if you are looking for a quality lightweight roll mat for pretty much any camping situation I would certainly advise the Exped syn mat 7 UL.
