An ultralight foam sleeping pad, waterproof closed-cell, folding, in blue.
fitply states ultra-light XPE foam with unfolded dimensions of
70.8 × 23.6 × 0.36 inches and folded dimensions of 23.6 × 5.6 × 4.9 inches, at
0.7 lbs per pack; an ergonomic design with raised nodes for back support, with
high and low nodes that nest inside each other for easy packing; a combination of
XPE foam and a heat-reflective aluminum film reflecting body heat, with the pad
stated to have “been tested to standard, with an insulation rating of 2.1”; that
unlike air mattresses it does not deflate; and that it is moisture-proof,
foldable and portable.
No standard named. No face fabric.
Two point one, tested to nothing named
The hedge this shelf’s introduction warns about.
“Has been tested to standard, with an insulation rating of 2.1.”
Which standard. Since ASTM F3340 gave the industry a common test, R-values can
finally be compared across makers — and the thing to check is that the figure is
quoted against it rather than invented in-house.
Not one of the eight mats in this group names ASTM F3340. The five figures
published here rank against each other and nothing beyond this shelf.
An aluminum film
How nine millimeters reaches 2.1.
Closed-cell foam resists conduction through its trapped gas. A metallized film
adds a radiant barrier on top, and on a mat this thin the film is doing a real
share of the work.
The cost is the surface. A film laminated to bare foam scuffs off against grit,
and there is no face fabric over it. Folding rather than rolling helps, because
the film is not dragged across itself.
Nodes that nest
Why it folds flat.
High and low nodes, which support the back when open and sit inside one another
when closed — so the pack is 4.9 inches thick rather than a seven-inch cylinder.
A flat rectangle rides against the back panel of a rucksack. A cylinder is
strapped outside it.
Of the three foam mats in this group, one folds accordion-style, one folds flat,
one rolls to seven inches.
Seventy point eight inches of mat
The shortest mat here.
A hundred and eighty centimeters, against 72 inches on five mats and 76 and 78 on
two air mats.
For a tall sleeper the feet come off the end, and this shelf’s introduction makes
width and length the trade-off that everything else hangs on.
fitply’s instructions carry the use. Nothing here replaces them, and nothing on
this page describes any product as safe.
