Active insulation layer

[USMC2378]

Is it lightweight? I want to say the original Sitka ambient is a 150 weight so looking for something much lighter

How is this outdoors vitals hybrid fleece compared to something like the Peckham USMC Polartec 1/2 zip in terms of comparable warmth does anyone have any experience with both? They weight about the same I believe my Peckham is about 10 oz in a small size and got it for under $10 at a yard sale.

If you can find the old Kelvin active hoody (the short sleeve one) Its not quite as warm and I can hike in it.

I have the original Sitka ambient hoody and really like it but it is very warm, almost too warm for me to hike in most of the time. I really like the alpha kind of insulation, what lighter options are out there? I know there's the ambient 75 but what else?

Go w/ 75 hoodie or outdoor vitals. The outdoor vitals pursuit hoodie hybrid is essentially the same thing with more color options. Nothing in that insulation range that breathes as well

I've given up on the active insulation hype; it might work for some, especially if you just wear it around town, but for me, I have yet to find one that actually works as advertised and doesn't get ripped or snagged on brush.

I tend to agree with this. I am going back to a tightly woven, button up wool shirt, which I have used for active cold weather chukar hunting for 20+ years in temps from 35-0F. I have just found it to provide the best combination of warmth and breathability when I am grinding up a mountain and moving. The loose knit sweater type wools don't protect well enough against wind or rain, but fine otherwise. Fleece just doesn't breath enough - same with a lot of the other options.

I will pull out the Kuiu Guide jacket, a puffy, or a rain jacket when conditions require, but I think a good wool shirt is best for active wear in moderate to colder weather. Other options best if raining or not moving fast enough to sweat, or if there is a real cold wind.

What wool shirt do you use?
