YMMV Review

Design ★★★★★

Arc’Teryx has really thought out the materials used in this jacket. The Hercules is a wind resistant softshell on the outside and super soft fleece on the inside. The outside fabric has stood up to abrasions and use while still looking new.

Inside Fabric

The inside fleece does not pile and is also still like new. While the jacket blocks most wind, it is not totally wind proof. The jacket will stand up to a light rain but is better layered under a shell for heavy downpours. The Hercules is fairly light weight for its warmth and layers under a shell nicely. The Polartec Powershield O2 fabric is really supple. There is no loss of mobility and the jacket moves really well when you do.

The pockets are fused to the jacket and perform well. Once again Arc’Teryx has made a piece that is made with utmost quality. There is a draw cord cinch at the bottom of the jacket to adjust the bottom hem. The wrist cuffs have a stretchy material to help keep the cuffs tight but allow easy on and off.


I was skeptical of this at first but they have worked well for me and I have never wished for an adjustable cuff. There are 5 pockets total. One chest pocket, two hand pockets, and two internal bag pockets. The chest pocket is a good size and the hand pockets are warm and cozy. I have not used the internal pockets much but they are nice to have if needed if there is not too much of a weight penalty. There is no hood on this jacket but they do offer a hooded version. Arc’Teryx has designed a nice jacket, I really like this one.

Fit ★★★★★

I am 5’11” and 160 lbs and I have this jacket in a medium. The jacket fits me really well. Arc’Teryx seems to have a European type fit which has always fits me well. This is no exception. The Hercules is trim but not tight. No excess fabric anywhere like many other jackets. The arms are of good length and so is the torso. The arms are gusseted so the jacket stays in place when you move your arms. The collar is the right height and pockets are great for warming your hands.

Wrist Cuff

While the cuffs are not adjustable, they are well thought out and I never felt the need for adjustable cuffs. This is a place that some people may differ on depending on their hand/wrist size.

Overall ★★★★★

I do not have much negative to say about this jacket. I wear it all around town and have used it as my warm layer on some hiking trips. The Hercules would also work well for snow sports in drier conditions. It is warm for the weight, easy to launder, and always a pleasure to wear. It packs down fairly well for stuffing in a pack. Fit is great for the skinnier body types. Slightly trimmer than some other brands which I really like. The only drawback to this would be the price for some, the Hyllus Jacket retails for $260. Everyone has a different amount they want to spend but I feel like this jacket is worth the money. If you need some more closeup pictures, Arc’Teryx does a good job on their site.  As with all my reviews, your mileage may vary.

Long Term Check-In

I do not have any real changes to my review after a year. Still my favorite jacket!

  1. Hi, I was looking into this jacket to wear in 45-55 degree Chicago urban use. Even though the jacket isn’t wind proof, does it still perform very well against wind? I was considering the North Face Summit Thermal jacket and Chromium jacket as well. Trying to decide which to go with amongst these 3.

    • Hello Joe,

      Thanks for the comment. This is definitely one of my favorite jackets and I have tried a lot. It is a bit more expensive than the Summitt Thermal and quite a bit more than the Chromuim. There are a couple reasons for that if you are curious, mainly it is because Arc’Teryx has more stitches per inch and higher standards for manufacturing. This will be slightly noticeable against the Summit Thermal and more noticeable versus the Chromium. Saying that, here is my comparison of the three:

      TNF Summit Thermal: Completely windproof and about 21 oz. Part of the Summit Series so its design will be more thought out as compared to the Chromium. Since it is windproof it will not breathe as well as the Hyllus. Not entirely sure but also not likely to be a soft and pliable as the Hyllus.
      TNF Chromium Jacket: Lesser fabrics as compared to the Summit Thermal. Also completely windproof and therefore less breathable. I would best describe it as a lesser expensive version of the Summit Thermal. Slightly lesser in design, construction, and fabrics.
      Arc’Teryx Hyllus: Most expensive but most finished of the three. Will block about 96% of wind. This little wind that gets through will not be really noticeable unless it is super windy then you may or may not notice it. It will breath much better than the others but also may not be quite as water resistant. Will be more trim fitting than the North Face Jackets. The North Face fits more boxy while the Arc’Teryx fit is slightly more European. I would not hesitate to recommend the Hyllus.

      Let em know if I can answer anything else for you. Thanks, hope you enjoyed the site!


  2. Hi JJ,

    Thanks for the info! How would you rank the warmth of the 3 jackets if you don’t take wind into consideration and then taking wind into consideration? I’ve tried to khumbu north face fleece and think that’d be good for 45-55 weather but the wind just cuts through it so I wouldn’t use it. Thanks!

    • Joe,

      I would give the Khumbu a 2, the Hyllus a 3.5 and the Chromium and Summit Thermal a 4. Since they do not breathe as well they will be warmer than the Hyllus. But not by much. The Khumbu is really just a lightweight fleece. Better under a jacket or warmer weather.


    • Hello Joe,

      I would rate them as follows:

      TNF Sentinel Thermal – 4, windproof with air trapping high loft fleece inside.
      TNF Denali WindPro – 3, windproof by thinner material will not trap as much awarm air inside.
      Arc’Teryx Hyllus – 3.5, nearly windproof with high-loft fleece interior.

      Let me know if you have any other questions. Arc’Teryx and The North Face will have entirely different fits.
