Clear, cogent, funny. I'm in love. With down, sure, but with the speaker here as well.

Another clear, concise and informative video about down fill power, fill weight and down treatments.
Like to see you explain the potential pro’s and con’s of different down jacket(or sleeping bag) construction materials and techniques.
I realise that it may be overkill and possibly too heavy for all but the gnarliest and harshest of British or European mountain conditions, but I’m impressed by the Rab Batura jacket.
In fact. I’d say it felt considerably warmer than it’s stated 800 FP.
Any of your colleagues or customers tried out the Rab Batura(or Resolution) jacket?
Looking forward to your next video.
Keep up the good work guys!
Best regards.

Good, please explain more about that graph, 1000 with 50 grams
& 500 FP with 100 gr. Down

I just bought a pillow with an inner chamber of 1000 power fill white polish goose down and an outer chamber of 700+ Eiderdown, which is of course higher quality than the 1000 goose down. I love it

Since i have a WM sleeping bag with 850+ i don't trust the numbers from the other company's anymore.

I often find myself waiting 40 minutes for a bus. If I’m not at the bus stop when it does 30mph around the corner I’m waiting again.
I do fine if I’m walking but due to my age🤔 and physical limitations I walk slow. What type or brand jacket would you recommend? I also like to hang out on my porch at 30 degrees but that’s cold to me. I saw a large grey fox last night and a red fox a month ago and 2 coyotes 30ft in front of me walk by while I was sitting and freezing. I don’t like sitting inside. I put a hand warmer in my Henley pocket but doesn’t help much. I even sit on a seat warmer but that only helps my butt. It’s my upper body that’s gets cold. I suppose spending more than $150 on a jacket might help. I put on a heavy T, a Henley, a hoodie and jacket but as each year goes by I get colder in New England (near Boston in USA). Any help or point me to some videos that might. Thank you

Fun fact: EU fill power ratings are 100 higher than US fill powers. So 850 EU is higher than its US equivalent.

Recently I purchased the Patagonia down sweater hoody and i returned it in a couple of days. It fit me well, it was warm but I just couldn't keep it because I was always terrified of tearing it due to the outer shell being so thin and quite fragile looking. As far as durability goes, down jackets just seem to be the worst in my opinion.
But again, I was surprised how warm and also breathable the jacket was.

Can it be possible to take down from an underperforming sleeping bag and transfer it to another with potential to perform better?

Thanks for posting. I found this helpful but I still struggle to fully understand.

Can I use my own jackets as an example:

I have an OEX down jacket, which is 285g of 700 full power, then I also have a Forclaz jacket which is 101g of 800 fill power.

The OEX is much thicker/ bigger and has the more ‘box’ stitching you refer to here, while the Forclaz is way lighter and has the ‘tube’ style.

Despite the Forclaz having more fill power, my OEX will be warmer because of the large box style stitching things, and that it’s just a thicker jacket. Is that correct?

Interesting you say the UK uses the US measurement for down fill power. I just assumed we use the European measurement as many websites go on about how European down is better quality at the same fill power as the US.
