A 0 Degree winter sleeping bag for adults and kids with a pillow, for four-season
camping.
MEREZA states a roomy rectangular shape fitting campers up to 7 feet at 32.3 by
90.5 inches, 20 per cent larger than most products on the market, with a
separated bottom zipper to ventilate the foot section and the ability to open
fully as a blanket; a comfort temperature of 40 ℉ for cold weather; a waterproof
and windproof 210T polyester taffeta shell with a 240T polyester lining, a net
weight of 5.73 pounds and a thick hollow cotton fill; a 220 g (7.8 oz) plush filling
camping pillow, a contoured 3D hood with drawstrings and a reversible locking
anti-snag zipper with draft tubes; and a compression sack with a large opening, a
reinforced top cover and a carry handle.
No limit rating. No standard. No denier. No packed size.
Zero, and forty
Forty degrees apart, on one page.
The title: 0 Degree Winter Sleeping Bag. The second bullet: comfort temperature
is 40 ℉.
This shelf’s introduction says which one matters — the comfort figure is the one to
compare. Read that way this is a mild three-season bag.
And the 0 is exactly the number this shelf’s introduction warns about: a bare figure
with no standard behind it cannot be lined up against a bag quoting EN 13537. At
least the 40 is labeled as a comfort temperature.
Two hundred and twenty grams, of pillow
The only fill weight on this shelf.
This shelf’s introduction makes the point about down: a high fill power alone tells
you nothing until you also read the fill weight, the grams actually in the bag.
The same holds for synthetic — thick hollow cotton is a description, not a
quantity.
Seven bags in this group. One grams-of-fill figure between them, and it belongs to
the pillow.
Two hundred and ten threads, which is not a denier
The nearest answer on this shelf.
T is threads per inch of woven fabric. Denier is the mass of the yarn. A 210T
taffeta and a 210D ripstop are different claims — a high thread count can be
woven from very fine yarn.
This shelf’s introduction asks for the denier because it predicts whether a shell
survives being dragged over gravel. Two bags here publish a T-count. None
publishes a denier.
Ninety point five inches
The largest bag in this group.
Up to seven feet of camper, against 6 ft 2 in and 5 ft 11 in on the two other
bags that publish a height limit — and nothing at all from the two Tetons.
This shelf’s introduction makes fit the last thing to read and the most important
one in a sense: length, shoulder girth and foot box shape decide dead air, and
dead air is what the rating assumes. A rectangular bag of 32.3 inches has a great
deal of air to warm.
MEREZA’s instructions carry the washing and the ratings. Nothing here replaces
them, and nothing on this page describes any product as safe.
