The same mat as our standard one, built 8 cm thick instead of 6 — for side sleepers, for anyone whose hip finds the ground through a thin mat, and for people who simply do not enjoy being folded into a narrow strip all night.

The manufacturer does not state the width, so we do not print one. If width matters to you, tell us before you order and we will measure the next one that passes through.
No R-value
Not stated by the manufacturer, so not printed here. This is an air mat, not an insulated foam mat: it lifts you off cold, wet ground and takes the lumps out. On frozen ground in deep winter, put a closed-cell foam mat underneath it.
No temperature rating
A number we did not test is a number we will not print.
This bag has not been laboratory-tested to ISO 23537, so a comfort figure would be a guess dressed up as data. Across this price band you will find the same physical bag advertised as −10 °C by one shop and −20 °C by another.
Use the fill weight instead. It is measurable, it is on this page, and it compares directly against bags that have been tested.

Straight talk
It ships from our partners in Asia, and it is priced accordingly.
That is why the same specification costs less here than on the high street, and why it takes 7–14 working days instead of two. Tracked the whole way, taxes settled at checkout, nothing to pay at the door.
Finish the system
A bag is half of it.
Down compressed under your body loses almost all its loft, so the underside of the bag insulates you barely at all. Without a mat, the ground takes the heat.
