A DWR coating makes it water resistant while retaining warmth in wet conditions. It also comes with a hood binding and hem cinch-cord for added warmth. It also comes with two covered zippered hand pocket and an inner chest pocket.

Who is it for?

The Thermoball is equally an excellent choice for anyone looking for a lightweight cold-weather jacket that holds up well against the elements.


What Makes A Great Down Jacket?

There are endless numbers of variables that determine which down jacket will suit you best. However, you want one that fits right, does not weigh too much, offers a reasonable amount of warmth, and provides water resistance. Your intended use should also guide the decision of going for a mid or lightweight jacket.


To begin with, down jackets come with the insulating layer that helps keep ducks and geese warm even when they swim through freezing water. Naturally, the more down layering, the better insulation provided.

Synthetic Versus Down Jackets

The first decision is figuring out whether or not to buy a down insulated jacket or a synthetic option. Down jackets provide significantly more warmth despite being lightweight, and they also compress better. On the other hand, the down jackets gradually lose their loft when they become wet which in turn comprises their ability to keep the wearer warm.


Synthetic insulated jackets come with more bulk while offering the same level of warmth. The PrimaLoft varieties are the most common types of synthetic jackets offered by both brands. The PrimaLoft microfibers provide superior thermal insulation and retain much of their loft when wet.   However, the synthetics do not compress down well. Downs tend to last longer, an average of 10 to 20 years, and they also provide better breathability.

Fill Power

One of the many confusing aspects of shopping for down jackets is the fact that they feature a “fill power rating.” You often see numbers like 400, 700, and 900 assigned to different products which raise curiosity for the regular shopper. The accompanying numbers reference the quality of the amount of down insulation used to construct the particular jacket.

Generally, the higher up the fill power number, the better the warmth-to-weight ratio meaning that you get a jacket that weighs significantly less but provides marginally better insulation.


Down jackets make use of two main types of construction which are the welded/bonded baffles and sewn-through methods. Most feature the hassle-free sewn-through construction method. It is a markedly cheaper method given that it makes use of less fabric making the entire process also less time-consuming.

The welded or bonded baffles technique fuse the outer and inner fabric pieces creating baffles held down using heat, glue, chemicals or a combination of the three. Given the lack of holes from sewing on the outer fabric, the welded baffles tend to provide better water resistance and wind impermeability.


The material used for the jacket also plays a hand in its overall performance. The amount of down filling, the fabric, zippers, and other hardware all contribute towards the weight. The material used also affects the durability and lighter and thinner materials more susceptible to snags and abrasions. However, the shell fabric often determines the longevity of any down jacket.


Compressibility matters too because it impacts how much abuse the garment can withstand without comprising its insulating abilities. It just means that you can stuff the down jacket inside your backpack without worrying about losing its insulation capabilities over time. When unpacked the downs regain their shape quickly.


Luckily, most down jackets come with a pocket, stuff sack, or a clip-able carabiner loop. It helps with storage and carrying the garment with you on your adventures.

Hydrophobic vs. Regular Down

The hydrophobic varieties come coated with a durable water repellent (DWR) finish which helps to repel water. These options significantly eliminate the setback of most downs which is their inability to maintain loft. That means that with one of these jackets on, you can still stay warm even in wet conditions.


You might spot a few brands marketing their down as having permanent water resistance capabilities. Given that it is a synthetic coating on the outer shell of the jacket that provides the water repelling abilities, it does not necessarily mean that the garment will stay that way during its lifespan.

How Do The Specs & Features Vary?

Aside from the distinct differences related to warmth, lighter jackets come with a variety of differing features. Some of the features that often appear across the board include waist and hood draw-cords, and marginally fewer pockets. Most come with hand-warmer, inner/outer chest, and internal stash pockets.


The hem drawstring helps give the jacket a tighter hold around the hips and wast. Similarly, the hoodie draw-cord gives a tighter fit around the head providing more warmth overall.

Most also just make use of one of the jacket’s pockets as a stuff sack which works better in reducing luggage when outdoor adventures.

What Are The Differences Between This Style Hoodie And A Sweatshirt?

Both down jackets and sweatshirts function as outerwear, but the former comes constructed out of cotton jersey fabrics while the next one features filling encased by an outer shell. The other distinct difference is how you wear a sweatshirt versus a jacket, with the first worn over the head and the second featuring an open front with buttons, zippers and hook closures.

A hooded sweatshirt works much like a sweater making it an excellent choice for mildly chilly weather, but it does not hold up too well as an option for extraordinarily freezing or rainy conditions. A down jacket hoodie works well as a winter-weather choice and depending on the level of warmth needed you can wear it on its own or alongside other warm apparels.

The reason why you want a hooded sweatshirt or down jacket is just that they keep you warmer in windy conditions.  However, you still have to factor in considerations such as whether you intend to wear the down jacket as a mid-layer and with a helmet or not.

The Final Verdict

When you take you a closer look at both brands there really is not that much difference between them. Both brands offer downs that are suitable for mid-season use and as layering garments for the colder seasons. Their down jackets also come with DWR coating which makes the garments water resistant.

Consumers generally find the Thermoball jackets to be a litter warmer when compared with the Nano puff jackets but the difference is almost negligible. The Nano puff jackets also provide windproof capabilities. Patagonia goes the extra mile and makes use of recyclable materials with 55% of their garments made using the recycled post-consumer content.

Both brands offer their jackets in relaxed fit sizes suitable for the outdoors.  However, the Nano puff tends to feature a slightly longer hem. The Thermoball women jackets come in tapered fittings while the men’s jackets come in roomier designs.

Their price points also much up which does not leave room to make a buying decision based solely on the cost. It mostly comes down to size/color and style preference when deciding to go with the Nano puff or Thermoball.
