What is fill power?

[@oaksbytheshore]

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

[@drewmonster6435]

I love the sound effects! Very informative video, thank you!

[@bulls_29favourite37]

Absolutely awesome info ❤

[@joseramoncanedoarrillaga9633]

You are the best. No discussion.

[@trekitt]

Thank you 🙏

[@Babel7078]

Those terms can be very confusing but you make things simple, thank's!

[@trekitt]

Glad we could help!

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.

[@trekitt]

Thanks for the kind words 🙌 we currently have one customer review on the Resolution: "This is a very light but extremely warm jacket, which if I'm honest, is a little too warm. Unless you're living or walking in sub zero conditions Id recommend a down jacket with a lower warmth rating."

[@bob-a-job]

Thanks for responding. Well. I was eventially hoping to use this jacket in sub-polar Alaska, Canadian, North Western US and Scandinavia. In temperatures as low as -25°C

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

[@trekitt]

That sounds expensive!

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

[@trekitt]

If you're stood/sat waiting for longer periods of time in fairly cold conditions then a more heavily insulated down or synthetic jacket would be a good option for you. The main considerations as to which way to go will be how much you plan on spending (upping your budget from $150 will help) and how much it rains in New England. Both for budget and wetter weather, a synthetic jacket will perform better as it will be more resistant to rain and will still keep you warm when it gets wet. However, it will be heavier and won't pack down as small if you need to pack it at any point. That's where a down filled jacket comes in to play. It will be warmer for it's weight and pack down smaller. In terms of options we probably won't go into any specifics as it's hard to know what is available over the Pond compared to our brands here, but a great place to start would be a visit to REI (or online), some of their own brand jackets could be solid options, as well as Columbia, Outdoor Research or if you can find them, Rab (one of our favourite Brit brands for insulation).

[@MrScrappydue]

@@trekitt it’s funny you should mention Columbia Jackets. I can answer my own questions better than there AI. It’s AI doesn’t understand I can’t walk around like the average person can. I don’t need to pack a jacket and rain can happen sometimes when I least expect it but for the most part I carry an umbrella. Last but not least I expect to pay a lot more than $150. Hopefully not over $500.

[@trekitt]

@@MrScrappydue Technology eh? Sometimes talking to a real person can go a long way. Righto, based on not needing to pack it, and carrying an umbrella, you'll get more warmth with a down jacket and with that budget you should have plenty of options. Some more specifics we can recommend that should be available to you, we've gone with REI because there's plenty of them around, but we're sure you'd find some of these jackets or very similar at your local outdoor store: www.rei.com/product/233771/mountain-hardwear-nevadan-down-parka-mens www.rei.com/product/234791/rei-co-op-stormhenge-850-down-hybrid-parka-mens www.rei.com/product/244476/rab-neutrino-pro-down-jacket-mens www.rei.com/product/244300/rab-valiance-down-jacket-mens - Warm and fully waterproof, the Valiance is a firm favourite for us at Trekitt. We've included a couple of parka options, worth considering as you get more coverage and will therefore be warmer, just look out for a two-way zip on any parkas so you can unzip the bottom a little before sitting down for more comfort.

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.

[@trekitt]

There are quite a few down jackets available with tougher outer fabrics. Mountain Equipment's Lightline, for example, has a pretty hefty outer fabric. It's not equivalent to a Down Sweater, but just as an example. Harry

Great video.

[@bobbymcdonald4365]

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

[@trekitt]

With a little sewing machine know-how and some patience it should be possible. You would be adding more insulation to one bag so it would be warmer, but also heavier and an increase in pack-size, you would also be adding more down to baffles that may not be designed for it. If you feel confident in your abilities it could be a fun project, or if that doesn't work out you can always look to a higher fill down bag for your colder adventures. It may also be worth looking at your sleep system overall to check why you feel your bag is underperforming. When was the last time you washed your down bag? And also, what are you sleeping on? Your sleeping mat plays a crucial part in insulating you from the ground and a clean, well lofted bag will perform much better.

[@Papa-ee8yr]

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

[@ianrudd7442]

Very useful

[@scherry2900]

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

[@thewhofan1964]

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.

[@trekitt]

It's very brand dependent unfortunately.

[@danielcanovas341]

Most UK brands use US measurements because it produces higher numbers with the exception of mountain equipment. Generally speaking the difference is 30 to 50 fill power.

[@DRM1891]

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?

[@trekitt]

Yes, correct. You're unlikely to feel a huge difference between 700 and 800 fill power in identical jackets, but you will notice over twice the physical amount of down.

[@sfoeric]

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