On my last visit to the Pacific Northwest this summer, I complimented Athletes for Cancer founder Tonia Farman on her Patagonia jacket who then let me know how essential her Nano Puff jacket is to her outdoor wardrobe.

This fall Patagonia sent us a Nano Puff jacket to try out and review. The jacket came in a simple flat envelope. My first impression was disbelief – I could not believe the package held an actual jacket as it weighed close to nothing. Upon putting it on it fit perfectly. The sleeves are slightly on the long side, the length is perfect, and there is room underneath for a layer or two when needed.

Men’s Patagonia Nano Puff Jacket

Now that I’ve used the Nano Puff for a few months, I can honestly say this is the most versatile jacket I’ve ever owned. Besides being amazingly lightweight and able to pack down into its own pocket for traveling or when hiking, I’ve found that the Patagonia Nano Puff is now my go-to jacket for a wide variety of conditions.

It’s an ideal layer to put on over a t-shirt to keep the chill off on warmer days and also keeps me surprisingly toasty warm on early morning walks when there’s still frost on the ground. I wore it as a layer to an outdoor party one night where temperatures were close to freezing. Others were dipping their hands in the hot tub to keep them warm before someone dragged over the giant outdoor heaters. I was perfectly comfortable in my Nano Puff.

Women’s Patagonia Nano Puff Jacket


  • Windproof and water resistant, surprisingly suitable for a wide variety of weather conditions and temperatures, outstanding Patagonia warranty.
  • Incredibly lightweight (10.5 oz), chest pocket doubles as a stuff sack, highly compressible, good variety of colors choices.
  • Good fit, ideal for movement when enjoying outdoor activities or layering for colder weather.


  • The jacket is very lightweight and I have yet to see how it will hold up with multiple washings and more use.
  • The Nano Puff is water resistant, but not waterproof.

The Verdict:

The Patagonia Nano Puff is an incredibly versatile jacket ideal for a wide variety of weather conditions and temperatures. About the only conditions I wouldn’t consider wearing it in would be going outside in torrential rain or blizzard-like weather because it is not waterproof.

The Nano Puff packs into it’s own chest pocket.

Feather-light and highly compressible, it conveniently packs down into its own pocket and will take up very little room in your luggage or backpack when not worn. You can also conveniently clip it to your gear or belt while partaking in your favorite activity. I do not think I need anything warmer than what this jacket provides for 99% of the weather conditions we get in Central California.
