Arc’teryx Atom Heavyweight Hoody Review
The Arc’teryx Atom Heavyweight Hoody is a high-end, synthetic insulated jacket for cold-weather applications.
Design and Construction
The Arc’teryx Atom Heavyweight Hoody, previously known as the Atom AR, is made of a combination of 120g, 80g, and 60g Coreloft insulation. This strategic “mapping” ensures that maximum warmth is provided where it’s most needed in the shoulders, outer sleeves, and sides, while lighter insulation in places like the underarms makes for excellent venting and keeps weight and bulk in check. The outer shell is made from lightweight, durable Tyono™ 30 fabric with a DWR (Durable Water Repellent) finish to shed light moisture. The jacket also features a helmet-compatible hood with a three-way adjuster and a small peak, offering great cover and protection.
Warmth and Weather Protection
The Atom Heavyweight Hoody has been designed to be extremely warm on those frigid days around town and in the backcountry. For an ideal balance between heat retention and light weight, different weights of Coreloft insulation have been used in the jacket. The wind-resistant shell and adjustable hood enhance the jacket’s ability to protect against the elements. However, it should be mentioned that this jacket may be too warm for high-output activities or cool-weather days.
Comfort and Fit
The Atom Hoody is designed for comfort. The Jacket fits well, snug yet secure, and the wrists seal up well with a close-fitting cuff. The jacket is a bit roomier in the mid section to allow for good layering over other clothes. However, the arms can feel a bit tight and the waist somewhat constricted when wearing multiple layers.
Breathability and Ventilation
While the Atom Heavyweight Hoody performs exceptionally well in terms of warmth and weather protection, it is less breathable than some of the lighter jackets on the market. The jacket features Permeair™ panels under the arms for breathability enhancement, but it can still be excessively warm during longer high-output activities. This positions it more as a static layering piece for rest stops or camp use rather than active pursuits.
Durability
Durability is one of the prime features of the Atom Heavyweight Hoody. The Tyono™ 30 shell is really hard and resistant to heavy outdoor use. The insulation of Coreloft is equally durable, retaining its loft and warmth even after extended use. It’s a great choice choice for frequent adventurers.
Pros and Cons
Pros:
- Really warm and protective
- Durable build with quality materials
- Comfortable Fitting and Adjustable Hood
- Excellent Resistance to Wind
- Activity That Tolerates Cold Weather well
Cons:
- Too Warm for high-output activities
- Breathability can be an issue

Conclusion
The Atom Heavyweight Hoody by Arc’teryx represents an ideal solution for all those seeking a highly durable jacket that will keep them warm on the very coldest of days. Regarding construction, the thoughtfulness of the design, and performance, this jacket belongs to the cream of the crop among synthetic insulated jackets. A tad too hot for high-output activities, but this is definitely worth the price for someone who frequently battles frigid conditions.
