Patagonia Micropuff vs. Nanopuff: Which one is better?

The Patagonia Micropuff and Nanopuff jackets are both iconic synthetic insulators, but they serve different primary purposes. The Micropuff is the clear winner for anyone prioritizing the lightest weight and best packability for travel and fast-paced activities, while the Nanopuff offers greater warmth, wind resistance, and durability, making it a more versatile workhorse for colder and windier conditions.

Patagonia Micropuff vs. Nanopuff Comparison

Warmth & Insulation

The core difference in warmth comes from the insulation and construction. The Nanopuff is unequivocally the warmer jacket. Its 60-g PrimaLoft® Gold Insulation Eco is a proven insulator, and the windproof ripstop shell does an excellent job of blocking cold drafts, which significantly contributes to retaining heat.

The Micropuff, with its PlumaFill insulation, is designed to provide impressive warmth for its extremely low weight. However, it's not as dense as the Nanopuff's insulation, and its shell is more wind-permeable. It's intended as a lightweight layer for cool, not cold, conditions or for staying warm during brief stops on the trail.

Weight & Packability

This is where the Micropuff truly shines. It is one of the lightest synthetic jackets on the market, designed to compress into a tiny package that can fit in any bag or clip onto a harness. It’s engineered for activities where saving space and shaving grams is critical, like long-distance trekking or alpine climbing.

The Nanopuff is still very packable and stuffs into its own internal chest pocket, but it is noticeably heavier and bulkier when compared directly to the Micropuff. For casual travel it’s perfectly sufficient, but serious minimalists will prefer the Micropuff.

Weather Resistance & Durability

Both jackets feature a DWR finish that successfully sheds light rain and snow, but neither is waterproof. The key difference is wind resistance and durability. The Nanopuff’s recycled polyester ripstop shell is tougher and almost completely windproof, making it a much better choice for blustery days.

The Micropuff’s Pertex® Quantum shell is softer and much lighter, but it can tear more easily and does not block wind nearly as effectively. It prioritizes breathability over an impenetrable barrier.

Price & Value

The Micropuff is typically around $20-$30 cheaper than the Nanopuff. If your sole priority is an ultralight insulating layer for activities where weight is paramount, the Micropuff offers excellent value. However, for most users, the Nanopuff's added warmth, durability, and wind resistance make it the more valuable and versatile jacket for a slight increase in price.

Which One Should You Choose?

Both jackets are top-performers, but the right one for you depends entirely on how and where you'll use it.

Choose the Patagonia Micropuff if:

• You prioritize the absolute lightest weight and highest packability.
• You need an emergency layer for fast-and-light activities like trail running or climbing.
• Your primary use is for backpacking or travel where every ounce matters.
• You plan to use it mainly for active pursuits where breathability is important.

Choose the Patagonia Nanopuff if:

• You need a versatile jacket for a wide range of conditions, from cold city streets to windy hiking trails.
• Wind resistance and sheer warmth are more important to you than minimal weight.
• You want a durable daily jacket that can handle regular wear and tear.
• You need a reliable mid-layer for colder-weather sports like skiing or snowshoeing.

Frequently Asked Questions

What’s the main difference between the Patagonia Micropuff and Nanopuff?

The main difference is their primary design goal. The Micropuff is built to be as light and packable as possible while still offering good warmth. The Nanopuff is designed to be a warmer, more durable, and more wind-resistant all-around jacket, trading some packability for increased performance in harsh weather.

Which Patagonia jacket is warmer, the Micropuff or Nanopuff?

The Nanopuff is warmer than the Micropuff. It has more insulation and a windproof shell that helps retain body heat more effectively in cold and windy conditions.

Are the Micropuff and Nanopuff waterproof?

No, neither jacket is waterproof, but both are water-resistant. They have a DWR (durable water repellent) finish that causes light rain and snow to bead up and roll off. For heavy rain, you'll need to layer a waterproof shell over them.

Can I layer under the Micropuff or Nanopuff?

Yes, both jackets feature a slim cut that works well for layering. You can comfortably wear a fleece or base layer underneath, and their streamlined design allows them to fit easily under a rain jacket or winter shell.

Do the Micropuff and Nanopuff jackets run true to size?

Yes, both jackets generally run true to size with a slim, athletic fit. If you are in between sizes or plan to wear bulky layers underneath, you might consider sizing up, but most people find their standard size works perfectly.

Which jacket is better for travel?

The Micropuff is often considered better for travel because of its superior lightweight design and extreme packability. It takes up minimal space in luggage or a daypack.

How should I wash my Patagonia jacket?

You should machine wash both jackets in cold or warm water on a gentle cycle using a mild laundry detergent. It's best to dry them on low heat with a couple of clean tennis balls to help restore the loft of the insulation. Do not use fabric softeners.

Are both jackets made from sustainable materials?

Yes. Both the Micropuff and the Nanopuff jackets use 100% recycled polyester for their shell, lining, and insulation. They are also both Fair Trade Certified™ sewn, meaning the people who made them earned a premium for their labor.
