True. Arcteryx has also become a status brand lately too, so you pay a premium for them - tho arguably they have better tech and your dollar goes further than LL Bean (in my experience of gear with both brands.) LL Bean isn't about spending your money on quality of gear but more for the logo and what it 'stands' for to people who see it. North Face is the same these days despite previously being about top quality technical gear, and yes, Arcteryx is heading that way (also Fjallraven.)

Interesting approach! The video is well done. I'd say at minimum you need a control though. Fred without a jacket so you could see how the heater behaves. Even better would be multiple measurements for each jacket. I definitely appreciate you buying this stuff so I don't have to!

@UIairi

3 ай бұрын

Yeah, I question this methodology as someone who owns one of those chest freezers. They're like +/- 10 degrees before they kick on, meaning the freezer may not have turned on at all for the first jacket, just cooling it ambiently. If it reached it's +10 degree trigger temperature for the second jacket, it may have been working to actively cool the second jacket instead, and potentially to a considerably cooler temperature then the first even experienced in its hour. Running the experiment for far longer and averaging each hour would be the easiest way to account for this. I think, if you wanted to absolute BEST experimental conditions though, not only is a control needed, but I'd recommend leaving all of the equipment in the freezer for several hours to let it all come to the same starting temperature, measuring the temperature in the freezer itself at the start of each test to rule out any large ambient temperature differentials between the tests, and THEN turning the heaters on with the freezer unplugged to rule out any interference from the freezer itself. Then you could measure the amount of energy it takes to bring each jacket to temperature, and the amount of time it takes to bring each jacket to temperature, which should give you cleaner data. Energy spent "maintaining temperature," as a real world reference, sounds good in theory, but there's too many variables to account for. This way you would also have the ambient temperature gauge in the freezer itself to provide a secondary data point, where a quicker rising, or higher overall, ambient temperature of the freezer itself would be the direct result of more heat loss from the jacket. Makes for a nice succinct experiment with three data points (time to target temperature, energy used to reach target temperature, freezer ambient temperature) that you can use to help isolate error as well.

@@UIairi This defeniterly deserves another more thourough test! The fact that the heavier jacket supposedly from the same material performed worse than the lighter one is already kind of a red flag.

The insulating properties of the fill are far less important than people are led to believe. What matters for an outdoor activity jacket in winter is how the humidity is managed. You can see on the LL Bean jacket with the aerogel that there is condensate forming around the underarms (3:39). This water then has to evaporate, and for this it will use the heat from your body, which is why you feel cold. The only way around this problem is to add loft so as to reduce the temperature gradient between the inside and the outside, so that the water vapor will not condense close to the body, but escape as vapor slowly through the outside of the shell. This is the advantage of wool, and why Scandinavians like to wear loose wool sweaters on the outside. It reduces condensate and reduces the heat loss in the process. The test model in the freezer, not sweating, totally overlooks this crucial problem.

Sitka, a hunting brand, has some items for the heat… but your color choices are limited to earth tones and camouflage. Drying time and protection from the sun seem, to me, to be the best indicators for how comfortable something’s going to be in the heat… covering up in the heat, while it seems counterintuitive, keeps you cooler than exposing skin; not least because sunburned skin is really bad at regulating temperature.

Been listening to some material engineer podcasts which started me thinking about various textiles. Seems like a pretty constrictive industry as they were saying one and a half cents per whatever unit they measure in can make an alternative material unviable in the marketplace so often the goal is to make a superior material that is equal or cheaper to the standard materials. It's super crappy to think about that we might be able to have much better materials for an extra few cents per garment, but they'll never manifest unless there's a potential marketing angle.

Aerogel was first created in 1931, not sure what NASA had to do with that. Aerogel works well when in encapsulated in a static structure as it's very fragile. Not so well when the structure isn't static, like a coat. It also doesn't pair well with other materials as it loses its insulating properties when there is any interruption in the coverage. I've owned a Shivershield coat for years. It retains heat amazingly well....and weighs about 5 lbs due to the lining required to maintain it.

what needs to be done, if not already, is to create tiny little packets of aerogel, like tiny beanbags or those silica gel packets you find in medication bottles and everywhere else, and pack those into jacket voids. Thereby you would have isolated little nuggets of warmth but it would not impede vapor or gas transmission if you want that as that all can pass around the packets. And you can make the packets sealed waterproof and tight in these little packet nuggets so if they get crushed or whatever it will not matter as I imagine it would last a long time before crumbling into nothingness. If you want to take it further you make the aerogel into a more rigid scaffolding like the pockets of waffles then seal that material. Lots of options could work. Even if the aerogel is crushed into 0.1cm pieces the particles of air trapped are still much much much smaller, so it would not affect the properties of insulation that much at all.

Well done. Interesting test.

That chamber is terrifying. One feature that might make a difference in the performance of the down vs the aerogel is that the down is fluffier. That would create slightly less contact between the interior of the jacket and your base layer, and those areas where it’s not touching would form more air pockets. If you had an aerogel jacket of the same volume and weight as an unpacked down jacket you might get a different result.

The problem is Primaloft are not selling aerogel jackets. Aerogel is stiff and dense. I own one of those Oros Aerogel jackets and a Haglofs lightweight primaloft aerogel insulator. The Haglofs one is pleasant to wear and pretty packable as it's using aerogel infused sheet synthetic insulation. Sheet insulation can be better than down for wind resistance (stitching issues in light down jackets) but it's not as good an insulator. Adding aerogel merely closes the gap to a hugh quality goose down of day 750-800 fill power. The Oros jacket is an amazing insulator for its thickness. It is heavier than any of my down jackets. It's comparable in weight to my old school waxed cotton and wool insulating coats. My wife sent hers back because she didn't like how hefty it was. Indeed it's like wearing a suit of insulating armour. There's not a huge market for heavy insulating jackets anymore, no matter how "high tech". Oros seems to be in financial difficulty and are out of stock. Primaloft have produced a good piece of marketing which also insulates well. It's not comparable to pure aerogel or even Oros' tech but it's more marketable.

that was a great video! I'm thoroughly impressed . That was one of the most scientific test on jackets.

Great video, and very interesting way to test the jackets! I would say testing against other synthetic jackets would be the next step. Time to get "Project Farm" all up in this!

I agree down is totally cruel which is why I had a custom made aerogel winter coat made by Prez Atelier and it’s warm and cosy to -10 degrees Celsius. Please understand not all aerogel is created equal. The hybrid material like the aerogels jackets used in this video are not as effective. My jacket is full aerogel blanket 3mm thick and I have used it for 3 years now living in Norway. So for him to say aerogel in general is not as warm as down feather is misleading. Proper aerogel lining which is a bit spongy like mine works brilliantly and I feel the cold easily. It can also be ordered in other thicknesses for colder than -10 degrees Celsius temps. Also, some companies cheat by just using aerogel panels and this doesn’t work either, needs to be full coverage of the whole garment. When NASA made it work for their spacesuits it obviously works and it absolutely works for me.

Well-designed and -conducted studies. Thank you.

Excellent video. Thank you for doing the hard work for this comparison.

Arc’teryx is just on a whole different level. I’ve worn their jackets through everything. Back country boarding in blizzards, the stuff is just better.

i doubt that a normal freezer will give repeatable results. they try to keep the temp in a (somewhat broad) range and only turn on for a short time. so, sometimes, the freezer is just colder than other times. to determine the insulation quality properly, you need to measure both the hot side AND the cold side. thats ∆t. good insulation means a slow rate of change and little energy needed to keep status quo. but if one side is unknown, then ∆t is unknown and the entire experiment becomes meaningless. the higher ∆t is, the greater the rate of change. tldr: if fridge temp is not repeatable, then it might be warmer or cooler than before. if not measured then numbers do not matter also, why the mannequin? it just introduced points of error. if the jackets were folded(all the same way), then it'd be better for accuracy

What I especially like is how compactable it is. It can stuff flat into a A4 mailer. I am allergic to down, so I need a synthetic alternative.

Don't forget IR reflectivity, an often overlooked factor in preventing heat from leaving in the first place. All critical factors: - insulation - IR reflectivity - air gaps around the wrists, neck and waist - windproofing - mild to moderate breathability to minimize water vapor buildup Best approach: Layering. Excellent test you devised concerning the measurement of power draw and time spent cycling the heating pad.

This had been my experience with my prima loft jacket. It's almost as warm as my down jacket. But because it is thinner and doesn't have the puffy jacket look, I wore it all the time and I end up layering it with my light down jacket when I needed the extra warmth. The two very light and packable jackets ended up being way better than the thick and heavy jackets I owned in the past.

I have the L.L. Bean jacket he has, same color, but just normal polyester insulation. It's freakishly warm and lightweight. I wouldn't wear it in wet conditions, but as a normal winter coat, it's wonderful. It's about as heavy as many windbreakers, but good down to 0F. At warmer temperatures, it doesn't feel hot, either.

What a solid review. Thank you!

I have been impressed with the jacket’s warmth and durability. The jacket is too expensive, but I bought them on sale. I find down is often too warm and so this layering system seems to work fine, but if it is below 25 then I go to down.

Hey you, yes you, the person watching this video. Your jacket is fine, you don't need to buy more stuff. Go out in nature and enjoy it.

I remember seeing this in a Popular Science magazine in 1990 as a option for winter jackets and home insulation.

Awesome video. I love the succinct science notes.

Thanks and I do appreciate you for making this video!

Good video, short and informative. Thank you!

Outstanding! Very informative video. Thank you for sharing.

You’re awesome! Your content and videos are so helpful and entertaining.

Great comparison video. Thanks!

You do crazy test haha, loved it, thanks ! 😅

columbia jackets with the omni heat always work very well for me over all the other down jackets I've tried.

Great test platform! I have an Oros jacket and I'd love to see it go up against a down jacket. Please make a follow up video if you can 😊

Interesting. I was just reading about a research team at Empa adding silica aerogel to glass bricks a few days ago, but I didn’t realize anyone had put it in clothing.

My Bogner ski jacket was a pretty penny. But it’s the warmest coat I’ve ever owned. Plus it’s water resistant for the slopes.

i wouldn't be surprised to see the aerogel hybrid insulation become the new standard in the synthetic game. even if it's not warmer than down, it's great to see improvements in the synthetic space.

Great test methodology!
