For various reasons I’ve found the good old wool and fleece mid layers leave much to be desired in some situations.
As a result I’ve stopped replacing them and put my money in the clothing category that’s now marketed as active insulation.
As always with these things, it’s being oversold to some degree, but going into it with reasonable expectations, I’ve found that this category has a something to offer.
What’s especially pleasing with this category is that there is fierce competition, so here in Norway you can regularly find the most popular offerings at 25-60% discount, making them actually cheaper than so called technical fleece most of the time.
I’m currently testing the Norrøna Octa jacket, Arc’Teryx Proton FL, Arc’Teryx Proton SL, Arc’Teryx Atom SL anorak, Rab Xenair light mountain jkt and the Patagonia Nano air hoody.
To keep this post from becoming prohibitively long, I’ll write more about how I use them and my experience so far in a follow up post, or several.
