Patagonia Nano Air Ultralight jacket

Kind of a mouthful, but pretty excited about this jacket. I have a Patagonia Nano Air Light hoody (actually two) that has been discontinued for some time, but close to a cult classic for an active insulating layer for cold to cold weather.

The" Ultralight" differs from the "Light" in that it has half the insulation— 20g/m2 vs 40 g/m2. Both I would consider very lightly insulated, 20 g/m2 is very (or ultra ) light. It is also full-zip where the Light was a pullover.

The insulation is "Full Range" which is Patagonia's labeling of Toray 3deFX insulation. If that sounds familiar, it should as I've reviewed three different jackets that utilize it—two from Outdoor Vitals and one from Kuiu.

I've found it to be the most efficient insulation in regards to weight to warmth and thus far the Ultralight has lived up to that.

I know this is ultralight, but how would you compare the insulation to the black diamond alpine start insulated?

I have one that's an old pull over. It is a great piece for layering, I don't know how it is so warm when layered under a puffy maybe it helps with wind blocking but its great.

Different insulations and different weights, the UL uses lighter insulation.

The biggest difference really is the outer fabric; the Alpine Start uses a pretty wind resistant fabric, the UL is very breathable.
