Patagonia Nano Air Ultralight Hoody Review

Thanks! I know you put lots of miles on. With these active insulation layers what kind of lifespan do you consider "good"?

I think you should be able 5-7 years out of an active insulation piece. My Patagonia Nano Air Light (discontinued) has close to 10 years, but I've also been subbing in some different pieces, so it's not seeing the same use it did 5 year ago.

The Alpha and Evolve pieces could last even longer; they're new enough that they don't have the years of use yet.
 
I just got a NAUL Freeride for backcountry skiing and hunting and was quite happy with how it preformed on top of a BD Alpenglow Pro sun hoody. I felt with some wind I was comfy from ~25-40 but started feeling a bit too warm in the direct sun beyond that. I'm excited to check this thing out for the fall hunting but I expect it'll be a bit too warm for the 50-60s as a moving layer.
 
Yeah I think 50’s and 60’s would be pushing it a bit for a moving layer—maybe under windier conditions. Everyone is different, but ~25-45 degrees was what I found to be the sweet spot.
 
I just got this to try. Wearing it to my shop and back I somehow I pulled a 6 Inch thread. I will be returning. It feels like the same story for a lot of these super lightweight mod layers is that they are too fragile.

My experience is less time, but I also crammed the s*** out of mine into a tight pack lots of times. Every time I took it off for a few years it went into a tight bag or rolled up and strapped tight to the exterior. I certainty can't contend another insulation would have done better, but just wanted to point out the obvious: life is dependent on use case.

I still wear my flat one fairly often, but I won't take it backpacking when I know it's going to be cold.
 
Yeah packing synthetic (even down too) tightly will definitely reduce loft over time.

I always pack my insulation layers in a lightweight dry bag, I try to get one that is sized about one size over the smallest the garment will fit in. Even then, they do eventually lose loft :(

I get a max of three years for most synthetic insulation. Even less with Climashield Apex.
