Patagonia Nano Puff

PURE Certified

Overall Review:

The Nano Puff jacket will provide you with practical and eco-friendly warmth.

Patagonia estimates that 2 million plastic bottles will be saved from landfills in the 1st year of production with the Nano Puff PrimaLoft Gold Eco insulation. In terms of performance, the Nano Puff kept us warm and comfortable through foggy San Francisco weather and the snowy slopes of the Sierras. This includes temperatures ranging from 30-60 degrees with 6 days of rain. We love how light and practical it is. With the ability to fold into its own pocket, the Nano Puff is an obvious choice for your daily travel bag. Read the full review below to learn more.

Recycled Insulation


Synthetically insulated jackets are comprised of an outer nylon shell with inner polyester fabric insulation. This polyester fabric is breathable, warm, water repellent, and a makes the jacket light/packable.


The Problem:
Polyester fabric is derived from petrochemicals that account for an estimated 70 million barrels of oil each year. Polyester production requires chemicals and carcinogens that wreak havoc on the environment if not properly treated.

Nylon, also derived from petrochemicals, emits nitrous oxide during manufacturing; a greenhouse gas 310x more potent than carbon dioxide. To top it off, these outdoor jackets are often coated with DWR (Durable Water Resistant), a combination of perfluorinated chemicals (PFC’s) that shed off during everyday wear and tear.


The Solution:

Patagonia teamed up with PrimaLoft to develop a line of jackets comprised of 55% recycled polyester fabric insulation coined as “PrimaLoft Gold Eco”. Patagonia estimates that 2 million recycled plastic bottles will be saved from landfills in the 1st year of production with PrimaLoft Gold Eco. The Nano Puff is the first of its kind and a leap in the right direction for synthetically insulated jackets. 


Although Patagonia hasn’t found an alternative to their non-rip nylon, they did verify its production through Bluesign Systems.

Bluesign is a third party endorsement company that partners with companies to ensure materials and manufacturing processes minimize the impact on people and the environment. This includes a focus on water and air emissions from chemicals, finishes, and dyes. Learn more about Patagonia’s partnership here.


The DWR coating is another work in progress for Patagonia. They recently implemented a reduced impact DWR by decreasing the number of compounds used in the coating (from C8 to C6). Patagonia is completely transparent about their use of DWR and investing heavily in an alternative we look forward to seeing.



Cities to Sierras


The testing began in late March and continues through today. Located in San Francisco, most days and nights were spent wearing the jacket around city parks, beaches, vistas, and streets. The conditions ranged from temperatures of 45-65 degrees with 6 days of rain. The Nano Puff came along on three snowboarding trips to the Sierras where temperatures averaged 30 degrees.


If you know this city, then you know the fog can come thicker than a spool of cotton by winds that hurl Recology trashcans down (& up) the street. Although it’s not a wind-breaker, the Nano Puff kept the wind from piercing our skin and left us dry as a bone on damper fog days.  In the face of real rain, we complimented the Nano Puff with Columbia’s Eco-Extreme rain shell. The Nano Puff held true in the Sierras, keeping us warm on the morning runs and around the accompanying villages/resorts.


The more you move, the warmer it gets. On hilly walks and warmer days in the snow, you will find yourself warming up faster than expected. Our best suggestion is to leave the jacket half zipped for air-flow because it can get toasty! If you do find the need to strip it off (woo-woo!), you’ll be impressed by its packability.


The Nano Puff can be packed into its own pocket at a size no larger than a pencil bag. This is ideal for temperamental climates that can go from hot to cold faster than the handle in your shower. The Nano Puff won’t make a dramatic difference in your daypack, but it will make a noticeable difference when the weather takes a turn for the worse!


“Better Than New”


One of the most admirable aspects of Patagonia is their pursuit to keep clothing out of landfills.

While wearing the nano-puff I got into a scooter accident that sent me skidding across the pavement at 20mph. The clothing I wore that day took a beating. My shoes were shredded, my jeans had lacerations, and my Nano Puff suffered tears. Determined to repair the puff, I did a quick google search and found Patagonia’s Worn Wear site that provides step by step instructions on repairing gear. I showed my local seamstress a WornWear guide on repairing Nano Puff jackets and chose a fabric to use for the patch. The jacket was repaired a day later for a grand total of $15. It’s new aloha print patches give the Nano Puff a personalized look and conversation starter.
