which jacket is warmer?

The Thermawrap parka uses 80g/m2 (2.6 oz/yd2) polyester filament insulation and the Micro Puff uses 2.6 oz/yd2 polyester filament insulation. They should be about equal in warmth with .6" of loft.

The Micropuff in the field is quite the warmer of the 2 jackets. I've used both and own the micropuff.
A BPL field test of lightweight synthetic insulated jackets came to the same conclusions. Not all synthetic insulation is created equal.

the thermawrap parka is very different in warmth compared to the jacket.

the jacket uses 50g/m2 excelloft
the parka uses 80g/m2

so the parka has a thicker loft and is the same as the micro puff

info from mont bell on the parka:

The heaviest and warmest of the Thermawrap jackets, the parka features a hood and more insulation to keep you warm in the worst conditions. Only slightly heavier than the basic jacket, but far warmer.

If warmth is your only concern, then the micro-puff is your ticket.

However, the MontBell scored higher in the useability dept according to BPL. Its more useable because it can be worn in a broader range of conditions, especially when combined with other layers.

Also, according to BPL, the Thermawrap insulation is 1.8oz/yd where as the Micropuff is 2.6oz/yd.

In the 1.8oz/yd group, it blew away its primaloft competetion in the areas of Loft to Weight Performance, value, and "average score" (except for the MEC which threw the curve with its $60 price point)

Edit: didnt see that the original post was compairing the Montbell PARKA.

If your compairing the Micropuff Jacket, with the MontBell parka (both hooded with equal loft) Id give the nod to the MontBell. Given its performance of the lighter jacket in the BPL review, and given that it weighs almost 8 oz lighter than the MicroPuff jacket. The MontBell also costs less.

The half-zip of the pullover would trap more air in than the Thermawrap Parka, although the Parka has a hood which is nice. I chose the Micropuff over it and found it to be very warm and great against wind. It is also lighter than what Patagonia says. My scale says more like eleven ounces not 12.5 so you would save some weight over the Montbell. The MP jacket is a lot heavier, though.

my bad on mistaking parka for jacket--- what becomes of a quick skim.

I have not used the new Montbell Parka --- but on a g. for g. basis--I believe that Polarguard Delta is more efficient than Exoloft ( excelloft ?). I believe that in part this is due to the need for less stabilization of the Delta insulation compared to Montbell's or others out there in use.

Quote: I believe that in part this is due to the need for less stabilization of the Delta insulation......

Dunno how you can say that, given that the Micropuff jacket is *heavily* quilted (it looks like the Michelin Man under the outer "floating" shell.

Quilting is not used in the BMW Cocoon Pullover( which I also have). The Patagonia's quilting, I think is a case of overkill. Still amazingly warm for it's 11.25 oz.(L) weight, regardless.

Perhaps Delta is more efficient due to the nature of the fiber architecture, instead.

And yes, getting back to the original poster--- the Montbell Parka is probably the warmer of the two by dint of the hood, alone.

Edited by kdesign on 11/07/2005 16:27:51 MST.

Im not sure that Delta IS more effecient. Ive felt far warmer in my excelloft bag vs any polarguard bag of similar insulation weight.

The Micropuff jacket has a hood as well, and weighs 20.5oz.

Joe-- jackets and parkas and pullovers have been bandied about on this thread, in a careless manner ( including by me)---you are right about the micropuff parka weight and hood, I was referring to my micropuff pullover. On the balance, I would say advantage Patagonia when it comes to comparing the jacket vs. Montbell's parka in the catagory of warmth.

It would be interesting to compare, side by side, a Montbell exceloft bag w/ an equivalent polarguard delta bag-- perhaps by cut and total weight rather than by temp. rating. Sounds like a future BPL project.
I suspect, that in the sleeping bag dept. that Delta has not been taken advantage above in terms of design as Montbell has with it's proprietary fill. I look forward to BMW's upcoming delta bags to rectify this somewhat.

Joe,

My 2004 L Patagonia Micro Puff Jacket weighs 17.4 oz. I believe the 2005 Model is heavier.

Very good, Ryan. And thanks for the smaller image sizes.:-)>

Richard--it's true, that was a better vintage.

the older thermawrap Jacket was lighter than the 2006 version as well.

2005 Jacket 7.9oz
2006 Jacket 8.8oz
Parka 12.7

Insulating Jackets

Ryan,

Just because a synthetic fiber fill is the same weight per ounce doesn't mean it is as warm, rebound from compression as well, be as warm when wet, have the same life expectancy, etc. Until we have tests we will not know if the Montbell Thermawrap Excel loft fill jacket is as warm as the Patagonia Polarguard Delt Micro Puff Jacket. No question however which product is lighter. Also with the new outer fabric of the Patagonia Jacket it is supposed to be tougher than last years model.

Rich

I never said if one was warmer or not, I was just comparing similarities and differences of the two jackets

but on the mont bell website it says thet exceloft will only reatin 1% of its weight in water.

makes decisions like these harder

Ryan,

The small amount of water absorbed by Primaloft is part of the argument for this insulation and why the Armed Services uses it. However, according to the tests by BPL last year they indicated that though Polarguard Delta did in fact absorb more water than Primaloft, Polarguard Delta appeared to maintain more warmth than Primaloft. I am not sure if BPL could make that comment last year due to the light insulation weight of the Excel Loft used in the Montbell products.

I am no expert on this kind of stuff, both polarguard delta and exceloft have their advantages, but me personally would go with the mont bell for the weight and money savings and just be careful not to get it wet (witch I would do any way.)

Edited by ryanf on 11/07/2005 20:26:48 MST.

Actually, what I would be FAR ,ore interested in were a long term BPL study that compaired insulations by weight.

Ill grant that PGDelta might be warmer new from the factory, but my research of raw insulation puts its long term durability in serious question.
