Cloudveil Enclosure Hooded Jacket

Just check your maths on the 200g/m2. I think you'll find it comes out at more like 5.89870494oz/yd2 {to the closest 8 decimal places :^)}

This plus the closer fit will help keep the weight down. Remember, weight/area doesn't equal loft. Think how puffy 200g of down would be for a m2.

So the 100g/m2 is 2.95oz/yd2. Now, assuming their stated weights are correct, let's allow 2.05oz for the hood including insulation. The added 2.95oz allows for a square yard of insulation. Could you make a jacket pattern out of this. Probably not. I figure you need about 1750 in2 or 1.35yd2 assuming a 24in sleeve and 25in back length with a 40in chest.

Still for a 6oz difference it sounds pretty possible.

Now as to how it performs, I have no idea.

Hi Rod

Not so fast. This is one of those places where it is dangerous to do a simple metric/imperial conversion.

You see, the convention in Europe and other metric countries is to quote the FINISHED weight of the fabric as gsm (or g/m2). This is all very simple.

But the convention in America is to quote the BASE weight of the fabric – before any coating or treatment is applied. As a result, you can have a '2 oz (per yd2) fabric' which ends up weighing 4 oz/yd2 in the consumer's hands.

But in addition, some American manufacturers don't even quote per 'square yard'. They will talk about a 5 oz fabric, but they are talking about a one yard length of mill width, what ever that may be! It could be 36 inches; it could be 50 inches!

Then we have the "sailmaker's yard". That's different again.

Finally, some people just can't do the maths correctly. I've seen that too.

I won't comment on which is the best system … you can guess my opinion. Me, I wait until I have weighed the fabric myself!

Cheers

You know me Roger, I'm a rusher.

In this instance though, we're talking insulation, not fabric, so I figured I was pretty safe. But I'll take your advice, and keep a weather eye out for those pesky sailmakers.

Roger, I didnt get your point. How is it relevant to insulation? Also Chris did give weights in 'square'.

Rod, you are right – my maths are off. That'll learn me to rattle off conversions without checking. By the way, you can use Google to do conversions – type "200 grams per square meter in ounces per square yard" in the Google search box!

However, the Cloudveil jacket still compares favorably in terms of weight, cost and insulation (just barely in the case of the latter) with the Patagonia DAS but I haven't heard of anyone using it.

Hi Huzefa

> How is it relevant to insulation?
I don't know.
The point I was trying to make is that fabric specifications are a real mess, and by extension synthetic insulation layer specs may also be 'uncertain'. Google conversion etc may be misleading.

I popped in to MEC yesterday and got them to weigh one of their medium Cloudveil Enclosures. The results are a bit inconclusive since the scale was meant for heavier objects and apparently isn't too accurate below 1kg (~35.5oz). They said it came up as 800g (~28oz). Assuming this is accurate, it's more in line with what I would expect it should weigh given the amount of insulation and fabric.
