Xtherm overweight

Mine weighs 15.4oz without repair kit or stuff sack. I doubt it's defective, but I could be wrong.

I had a Xtherm regular and, if I remember correctly, it weighed 15oz with the stuff sack and repair kit. It was under weight without the peripherals.

Best to give Cascade Designs a call if
you have concerns about it.

They are very good to deal with.

have you had it a while? could just be moisture from inflation in there.

Joshua, it's brandnew. The weight is as weighed fresh out of the package. Weighed it again after having inflated it once with the stuffsack, but that didn't influence the weight.

Most likely just poor luck. There will be some variability in weights when using coated fabrics. Personally, I would take it back where I bought it and try another one. Yes, I understand how silly that statement is.

Check your dimensions, you may have an "oversized" regular. I have seen more variability in weight due to extra length on Neoair pads. My son has an All Season large that is 82" long fully inflated and a bit over stated weight. I have an Xtherm that was slighly overweight and a buddy of mine has an Xtherm that came right in on spec. My mat is also nearly 3 inches longer than his mat and that's fine with me.

My XTherm, made in Ireland, is 463 grams ( or 16.3 ozs) so its heavier than yours. What is normal? is a good question, as there is always some variation in manufacturing. Maybe the Irish version weighs a little more.

Hi Roger,

I had forgotten about Cascade Designs Irish operation, it is in fact
about 10 km from where I grew up.

Well, manufacturers should indicate the deviation of the listed weight which is often between 5 and 10% +/- of that listed weight.

I had a Small XTherm and it came in a little under weight.

The weight is within 10%. I don't think it's defective. Probably just a little bigger and/or slightly more durable than normal (maybe slightly heavier fabric or more glue, etc).

My regular Xtherm is 15.81oz (449g) with a repair patch on it.

I just happened to put mine on the scales the other day, it came in at 16oz's not including the stuff stack which I never intended to use anyways. It's also unused which means moisture isn't the issue, but I rarely expect the specs to be perfect on most of the items I purchase. It would be nice, but I'm never optimistic.

Although with cascade designs I have noticed that they typically overstate the weight of their products so this I suppose was a bit of a shock.

I have two large xtherms. My used one, which has been unused and dried out hanging in the closet with valve open since last winter is 22.25 oz. .The second one is brand new in the box, I took it out only to weigh it, 20.20 oz….hmmmm

Mine's 388 with an advertised 410.
I'll sell it for $190.

:D

a <10% variance in consumer goods is not uncommon

and honestly its not something to worry over for practical purposes … youll get some gear thats under and others thats over, thats life

and its one of the reason why worrying about every last theoretical ounce is an exercise in futility …

not to say you shouldnt save weight …. but not obsessing over theoretical spreadsheet oz when theres variance in real life

i remember awhile back when someone was bragging about how their down jacket (or bag i forget) came in underweight … my natural response was "how do you know they didnt just put less down in there?"

;)

And clothing is another matter as the weight is mostly for a size M. Now, what if your e.g. an XL ? Now, somechere I found that for each size up or down, you can add or substract 5% to the weight of the previous or next size e.g. an XL's mean weight is then the listed weight (thus often that of the M) * 1,05 and that result again * 1,05. And then that weight again has a deviation of +/- 10%. I do that for shoes too. How, that doesn't mean that deviations of more then 10% can't occur as a deviation tells you just something about the reliability of the mean-value.

Not that it indeed really matters. You have what you have.

Yup, I've bought two xtherms in the last year and both weighed 450g (15.8 ounces), not the 420 grams they advertised. It is annoying.

It would be interesting to see the all the items weighed on the same scale.

Like with manufacturing tolerances I expect there could be some variations among scales?

Re: Could the variation be due to scale differences?

Yeah, I thought about that but it can't explain the differences I've observed on my neoairs. I calibrated my scale by measuring 500ml of water and weighing it – it weighed exactly 500 grams as it should.
