"update your garments when new firmware becomes available."
Now there's a sentence that I suspect we wouldn't have imagined 10 years ago...
Now if only she would gift me one in return...
My husband got me this heated blanket from LL Bean and it is my absolute favorite gift he's given me in 15 years together! This thing is amazing! I want to wfh just to curl my feet in the blanket. https://www.llbean.com/llb/shop/124706
I want to get one for every family member now.
They're thick padded cotton, and once the vest has warmed up (which doesn't take too much time) it's really warm and comfy, if a tad bulky.
Not a factor when (again) not exposed to the elements.
> I suspect the reputation of this type of jacket is more cultural than anything.
It really is not. I suggested it from experience because I have one in my closet.
I use them occasionally if I get cold hands.
"Low-tech Magazine questions the blind belief in technological progress, and talks about the potential of past and often forgotten knowledge and technologies when it comes to designing a sustainable society."
Personally I find that either I'm doing low intensity physical activity and I can just put on my Sorel Glacier XT boots and Hestra Army Leather mitts and stay warm, or I'm doing something more high intensity and my feet and hands only need normal boots and gloves.
In both cases I wear a thick merino base layer, fleece midlayer with varying thickness according to temperature and activity level, and GoreTex Pro outer layer that has zippers under arms and along thighs such that you can adapt ventilation seamlessly to variations in activity level. This works nicely from +5 C all the way down to -30 or -40 C (depending on wind chill and humidity, you might not last very long at -40 C though).
I use it for a motorcycle jacket.
It's been a number of years since I've done this research, so your options should be even more broad now, because heated clothing that isn't motorcycle/snowmobile-specific is a relatively new thing (thanks, lithium batteries!).
Anyway, the stuff is out there, you'll just have to go look for it.
And I don't mean to keep promoting this brand but I've got their heated ski gloves too and they're amazing. I was night skiing and saw that one of the ski patrol ladies had a lit LED on her gloves. I asked her what that was and he told me it was this: https://fieldsheer.com/collections/womens/products/storm-glo... (wait, I wear women's gloves?) They're fantastic, I wore them skiing in 10ºF Vermont weather from 9am to 3pm on low heat. The batteries died around 3ish but I had hand warmers after that.
