R-value carries the warmth; thickness decides whether your hip lands · review
A large foil-faced foam mat that publishes its two ground dimensions and nothing else: no R-value, no thickness, no weight.
A 200 × 200 cm (78.7 × 78.7 in) mat with a pearl-cotton foam core and double-sided aluminum foil, a storage bag, and claims of insulation, waterproofing and durability. Nothing is measured except the two ground dimensions.
R-value. It measures resistance to heat flow, and since ASTM F3340 gave the industry a common test, R-values from different makers can be compared directly. This listing has none, and names no standard.
That matters more on a foam mat than it looks, because R-values add. A foam mat under an inflatable one gives you the sum — but only if you know what you are adding.
Thickness. On foam it is the whole comfort question: it decides whether a hip reaches the ground through the compressed part. It is not published.
200 × 200 cm (78.7 × 78.7 in) is not a sleeping mat footprint. It is a tent-floor liner, a group ground sheet, a picnic square. Read it that way and the absence of a packed size and a weight matters less.
If this is going under an inflatable mat for warmth, ask the seller for the thickness. If it is going in a tent as a floor liner, measure your tent first — 200 × 200 cm (78.7 × 78.7 in) will need trimming or folding in most two-person tents.

| R-value | Not published on the listing — insulation and warmth are claimed in words, with no figure |
|---|---|
| Standard quoted | None named — no ASTM F3340 reference appears in the listing |
| Thickness | Not published on the listing |
| Packed size | Not published on the listing — a storage bag is supplied and its dimensions are not given |
| Weight | Not published on the listing |
| Width | 200 cm (78.7 in) — stated as part of a 200 × 200 cm (78.7 × 78.7 in) size |
| Length | 200 cm (78.7 in) — stated as part of a 200 × 200 cm (78.7 × 78.7 in) size |
| Fabric denier | Not published on the listing — the mat is a foam core faced with aluminum foil rather than a coated fabric, so no denier applies |
| Inflation method | None — a closed foam mat with foil faces; there is nothing to inflate and nothing to puncture |

It reflects radiant heat back, which helps a little; most of the insulation in a mat like this comes from the closed-cell foam holding still air. Without an R-value figure there is no way to say how much either contributes.
Because it cannot fail. An air mat that punctures at midnight leaves you on the ground; foam is the same in the morning as it was at dusk. R-values also add up, so a thin foam mat under an inflatable one gives you the sum of the two.
No. Not published on the listing — insulation and warmth are claimed in words, with no figure. What the listing does publish instead is the width: 200 cm (78.7 in) — stated as part of a 200 × 200 cm (78.7 × 78.7 in) size.
7.2/ 10
A large, cheap, unpuncturable square with no numbers behind its insulation. As a tent-floor liner or a group mat it does a job nothing else here does; as a sleeping mat compared on specification, it publishes almost nothing.
A tent floor liner or a group ground sheet at a driven-to pitch, rather than a mat carried on a back.

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.
