R-value carries the warmth; thickness decides whether your hip lands · review
A wide air mat that publishes every dimension, its weight, its fabric and its inflation time — and no R-value, which is the figure a mat is chosen on.
An inflated size of 195 × 70 × 9 cm (76.8 × 27.6 × 3.5 in), an integrated pillow 14.5 cm (5.7 in) thick, a built-in foot pump stated at 60 seconds to inflate and one second to deflate through a double-layer leak-proof valve, a packed size of 33 × 14 cm (13 × 5.5 in), a weight of 950 g (33.5 oz), 75D nylon with an inner TPU sealing coating, and side buttons that join two mats into a double.
Nine dimensions, a weight, a fabric and two times — this listing is unusually complete. And it has no R-value.
R-value is the measure of resistance to heat flow, and since ASTM F3340 the figures from different makers can be compared directly. Without it, a 9 cm (3.5 in) air mat is a comfort claim rather than a warmth one: air moves inside an uninsulated chamber, and thickness alone does not stop cold coming up.
75D nylon. The thickest face of any air mat here — roughly twice the yarn weight of the 40D mats. On grit, pine litter and gravel that is the difference that shows up on the third trip rather than the first.
It is also 950 g (33.5 oz). The lightest mat in this group is 550 g (19.4 oz) on 40D. That 400 g (14.1 oz) is the fabric.
The body is 9 cm (3.5 in); the integrated pillow is 14.5 cm (5.7 in). Both figures are given and how the two meet is not described, so whether the pillow is a raised section or a separate chamber is unclear from the page.
70 cm (27.6 in) across is genuinely wide for one — most mats here are 63 to 68 cm (24.8 to 26.8 in). If two of these are being joined, check the tent floor width first.
The American Amazon store returned nothing, so the buy link opens a local search rather than a page that is not there.

|---|---|
| Standard quoted | None named — no ASTM F3340 reference appears in the listing |
| Thickness | 9 cm (3.5 in) — stated as the inflated thickness; the integrated pillow is given separately at 14.5 cm (5.7 in) |

| Weight | 950 g (33.5 oz) — stated, with no label saying what is counted |
| Width | 70 cm (27.6 in) — stated as part of a 195 × 70 × 9 cm (76.8 × 27.6 × 3.5 in) inflated size |
| Length | 195 cm (76.8 in) — stated as part of a 195 × 70 × 9 cm (76.8 × 27.6 × 3.5 in) inflated size |
| Fabric denier | 75D nylon — stated, with an inner TPU sealing coating |
| Inflation method | Integrated foot pump — stated at 60 seconds to inflate and one second to deflate, through a double-layer valve |

How much the mat slows heat leaving your body into the ground. An air mat with no insulating structure inside can be thick and still cold, because convection moves heat around inside the chambers. Thickness and R-value are different questions, and only one of them is answered on this page.
On rough ground, often yes. Denier weighs the yarn: 75D is roughly twice the 40D used on most mats here, and it is the difference between a mat that shrugs off a pine needle and one that does not. It is also why this mat weighs 950 g (33.5 oz) and the lightest here weighs 550 g (19.4 oz).
No. Not published on the listing — insulation against cold ground is claimed in words, with no figure. What the listing does publish instead is the inflation method: Integrated foot pump — stated at 60 seconds to inflate and one second to deflate, through a double-layer valve.
7.8/ 10
The best-measured air mat of the nine on everything except warmth. If you sleep on your side and camp on rough ground the 9 cm (3.5 in) and the 75D fabric are the right trade; if the ground is cold, nothing here tells you how it will do.
Side sleepers who want 9 cm (3.5 in) under the hip and a tougher 75D face, at pitches where 950 g (33.5 oz) is acceptable.

R 2.1, standard unnamed · XPE foam with aluminum film · 70.8 × 23.6 × 0.36 in · 0.7 lb
A folding XPE foam mat with a heat-reflective aluminum film and a published insulation rating of 2.1 — "tested to standard", with the standard never named.
Best for: A foam layer that packs flat rather than rolled, with a figure behind its warmth
≈ $25
531 g (18.7 oz) · 190 × 60 cm (74.8 × 23.6 in) inflated and 225 × 70 cm (88.6 × 27.6 in) flat · 40D material · inflated by breath · repair kit included · no R-value
A 531 g (18.7 oz) mat that publishes both its flat and its inflated dimensions — an honest distinction most listings skip — and no thickness and no R-value.
Best for: Lightweight trips where 531 g (18.7 oz) and a 190 cm (74.8 in) sleeping length are the specification, and warmth comes from the bag.
Built-in foot pump · 40D nylon/TPU · 78 × 27 in · 3 in in one line, 8 in in the next
The widest mat in this group at twenty-seven inches, with a built-in foot pump, a built-in pillow and side buttons to join two together — and a thickness published as three inches and as eight.
Best for: Two mats buttoned into a double bed, with no separate pump or pillow to pack
