The Thermoball Jacket by North Face is synthetic fiber insulation clothing that resembles down in terms of structure and utility. With its exceptional warmth, light weight, compressed size, and appealing look, the jacket is currently the best offering available to withstand extremely cold weather.


The jacket gives an impression of down when it comes to appearance and function. However, it is made of thermoball clusters that retain heat and warmth to give pleasant experience in cold and wet weather conditions.

The jacket features two zippered hand pockets, elastic cuffs, and a hem cinch cord. It is quite light with just about 11.5 ounces of weight. The compressibility allows the garment to compress into its own pockets.

In terms of design, Thermoball jacket offers style as well as great functionality. The versatility in the design can suit the taste and style of anyone. Whether you are an athlete, traveler, or simply a winter lover, this light and warm jacket can be the perfect choice for comfortable cold weather activities.


Considering the features and design of the Thermoball jacket, it can be fairly said that the tag price of $200 offers an excellent value. It offers warmth of down, is compressible, and dries quickly if it gets wet. You cannot find such great features at this reasonable price in any other clothing product.

Warmth-to-Weight Ratio

The North Face claims that the Thermoball Jacket offers an exceptional warmth-to-weight ratio with its stuffed fluffy spheres of polyester fiber. An independent study by Kansas State University confirms that the jacket has the capacity to deliver warmth on a par with 600 fill goose down.

Besides, the users verify the claim saying that the jacket’s synthetic structure along with well designed features including elastic cuffs and hem cinch cord, deliver outstanding warmth-to-weight ratio.

Weight and Compressibility

Thermoball Jacket is amongst the most lightweight jackets available in the market. The feathery spherical insulation, sewn in small pockets as well as other efficient features makes this jacket the best option in the lightweight jackets category.

In addition, the exceptional compressibility of jacket allows the garment to stow in its own hand pocket and return to its great loft quickly. It can be compressed into a small, handy shape that be carried easily and conveniently through climbing and hiking.

Resistance to Water

Unlike down, the synthetic insulation in the Thermoball does not soak water and maintains its loft even when wet which keeps your body warm and comfortable no matter what the conditions are. The durable water repellent (DWR) in the jacket allows protection in light rain. However, the North Face suggests the use of waterproof coats over this jacket in heavy downpour.


The North Face has not just taken care of warmth and comfort, but also the design and style. The elegant designs and various sizes are offered to perfectly fit on your body. With a variety of color, you can choose the one that defines your personal style and taste.
