TNF Red Blaze seems too good to be true

Just having a look around at some various synthetic insulated jackets today, and stumbled upon this:
TNF Red Blaze Jacket
http://www.thenorthface.com/catalog/sc-gear/men-39-s-red-blaze-jacket.html
Most important were these few specs:
Shell: 1.9oz/sq yd nylon
Insulation: 133g PrimaLoft Eco
Total weight: 12.4oz

This is rather remarkable, no? That's 1.5 or 2.5x the amount of insulation as similar jackets at that weight. Examples:

Patagonia Micropuff Jacket
http://www.patagonia.com/us/product/mens-micro-puff-jacket?p=83907-1
Shell: 1.7oz/sq yd nylon
Insulation: 100g PrimaLoft Sport
Total weight: 16.4oz

Lighter shell fabric, lighter insulation … but ~4oz heavier? Huh?

Or this:
Montbell Thermawrap BC Jacket
http://montbell.us/products/disp.php?cat_id=2002&p_id=2301140
Shell: 12 denier ballistic airlight (which we know is really light)
Insulation: 50g Exceloft in sleeves; 80g Exceloft in body
Total weight: 12.8oz

This second example has significantly lighter insulation, probably much lighter shell fabric, but weighs the same??

So … there you have my quandary. Either The North Face has stumbled upon a rather impressive new method for constructing these things (and is not making any noise about it) or the listed specs for the Red Blaze must be wrong somehow.

Whatcha guys think?

Either they are listing the specs wrong or quoting the weight of that Xtra Small model instead of the normal Medium.

I bet there's a mistake there somewhere. Do the math:
133 gm/sq. m = 3.92 oz/sq yd
even if the liner is .9 oz fabric, you have 1.9 plus .9 plus 3.92 which is 6.72 oz/ sq. yd. for the sandwich. It has 3 pockets and a full front zip. That's going to be about 2 ounces for zips and misc.. That leaves 10.4 oz – which means you have to make a jacket that takes only a 1.54 sq yds. For comparison I have the numbers from a thru-hiker pullover pattern – it's 1.79 sq yds , and that's pretty snug – I also have numbers from a pattern I made for a MYOG insulated pullover which was 2.02 sq yds. for a medium size.

Incidentally, they say the outer fabric is 54 g/sq m and also that its 1.9 oz, but 54 gm/sq m calcs out to 1.6 oz./sq yd so they're off somewhere or perhaps in more than one place.

Welp, I suppose that settles it. Thanks for the detailed analysis Paul. Too bad though, that was exciting! 133g insulation in 12oz piece would have been (maybe?) approaching the efficiency of a down jacket. I guess we're not there yet :-)

Pl sport is a budget insulation option … The micropoofay used to have PL1, but patagucci changed it to save moola

Of course they will give u the marketing yak yak goobly corporate speak about how its more "suitable" but the fact is you are getting less for the same moola from a year or two ago for them to pinch pennies

PL eco has even worse clo values … At least they have the excuse of it being recycled

Unless u find a deep sale get PL1 … Dont pay $$$$ for second rate insulation

Companies are always trying to substitute top end materials with marketing

Note even "budget" brands like MEC and LL Bean use PL1 …

Its destroys any credence these "high end" companirs have of having "top notch" gear

There is a TNF store close to me. I'll try to get by there with a scale.

They were over by 2oz on the Verto 26 pack that they spec'd at 11oz. That is what, about 18%?

If there is anything learned by all the info provided by BPL forums, it is that the main line manufacturers are weak on accurate reporting on weights.

It's not just hiking gear. Consumer Reports thrives on such stuff. Of course, who would get excited about a couple ounces. GRAM WEENIES UNITE :)

I call shenanigans. My Rab Xenon in size medium is made with 60g PL1 and Pertex Quantum GL, with minimal quilting, and it weighs a bit over 10.5oz, so I don't see how something with over twice the insulation and much heavier fabric can come in at that weight (even without the hood). The difference in insulation weight alone would be over 2oz.

I went to a TNF factory store and weighed a medium Red Blaze on my digital scale: 19.0 ounces with the tags. The manager looked in the TNF tech book and it shows 12.5 oz. I would chalk it up to a typo. The actual weight is comparable to other 100g style jackets.

To compare, their specs on the Thermoball are very accurate.

Caveat emptor!

Nice work Dale. I can just picture the store manager noticing the typo and shrugging it off — what's ~7oz anyway? — he says.

… whereas the BPL community goes What a travesty!!

Actually the store manager greeted me as I came in and he assisted me in weighing the jacket. He was very interested and invested in the process. He went and got the tech book to check the published weight. He's a climber and looked the part. We had a good chat. He's worked for TNF for quite a while and has a good grip on their place in the market.

He was surprised how far off the specs were. A couple ounces can be understood, but having the garment weigh 50% more than advertised is a big error for a major player in the market and sacrilege here. Ooops!
