Nano Puff vs Down Sweater Hoody: Performance Review


Honestly, we would prefer Patagonia Down Sweater over Nano Puff. Because it keeps warmer than the Nano Puff, but it is less water resistant. The only down side of this jacket is the wet environment. As a result of being a down jacket, when the Patagonia Down Sweater gets wet, you will be no longer protected from the cold. However, as we know that the synthetic insulation dries faster. On this circumstance, the Nano Puff will get dry faster and will be more protective.


From the durability stand point, the Down Sweater still does better job than the Nano Puff. Here are the details of their fabric structure:

  • Nano Puff: 1.4-oz 20-denier for shell and 1.3-oz 22-denier for lining
  • Down Sweater: 1.4-oz 20×30-denier in shell and 1.4-oz 20-denier in lining


The Nano Puff uses 60 gr Primaloft Gold Eco, whereas, the Down Sweater has 800-fill Advanced down fill. The synthetic insulation of Nano Puff lost its capability to provide warmth in wet condition. The only good thing about this jacket is its synthetic insulation gets dry faster than Down Sweater.

Water Resistance

Both jackets are water resistant up to a point but not completely. They are DWR coated which tries to keep the water out. Based on our own experience, the Down Sweater is better compared to the Nano Puff when it comes to water resistance. Just keep in mind, when it gets wet, here comes the trouble.

Frankly, it is hard to pack those two jackets in to their pocket. But, it is still possible. From the compressibility and pack-ability stand point, Nano Puff is a slightly better option to consider.
