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.


  • Warm, soft!, unrestrictive fabric

Long Term Check-In

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