Hello, I was just wondering, was there a major difference in the fitting of the 2008 epsilon and the 2010 epsilon?? From what I've noticed from reviews is that the newer model runs big. Is the older model much slimmer like the gamme mx?

Best Answer Responded on

The new pattern on the Epsilon doesn't run big, but it fits better. It's still cut to be worn as an outer jacket in medium conditions, but layered under a Gore-tex shell if the weather's getting really good. The cut is different from the MX because of the different stretch properties of the two, but, yes, it's still a fairly close fit.

Arc'teryx Epsilon AR Softshell Jacket

The jacket pictured here is last year's model, but I've worn the new one and I think this model is at least as nice. Perfect for a backcountry ski jacket - breathable for the uphill and then throw a shell over it for the down. The Epsilon has every bit of Arc'teryx reliability and quality that you would expect. I also really like the Amazon color for casual wear in Spring and Fall.

My new favorite jacket

My Marmot Superhero used to be my goto, but I often found it too warm and the high collar too technical looking. Enter the Epsilon. It could be the perfect fall/spring jacket, except I find myself grabbing it as I run out of the house in the winter. The only problem I've had is that wearing it so often I'm getting it quite dirty. I may need to buy another to keep clean.

FYI 6'2" 170lbs. Tall and skinny and the Large fits perfect.

good construction, odd fit.

A well made jacket but the cut/sizing was very different from what I have come to expect from Arcteryx. Where most Arcteryx stuff is slim fitting through the chest and at the waist, the Epsilon AR was surprisingly puffy at the hips and waist, and was thus way too big for me. I'm 5-7 and 140lbs and the S was way too roomy for me. I could have fit a fleece and a 800-fill down puffer underneath it with no problem. Was looking for a new softshell for skiing this season, and ended up returning this and going with a Mountain Hardwear G50, which fits perfectly, and can house a Patagonia micropuff vest underneath...

i am debating between the epsilon ar and the gamma lt.

background...i live in michigan and spend a lot of time in northern michigan. this will be used for hiking, snowshoeing (both with and without a pack), skiing, snowboarding, tailgating, football and soccer games.

which jacket, the epsilon ar or the gamma lt will best suit my needs?

thank you

comparing the Arc'teryx Gamma AR and Epsilon AR. The Gamma is warmer, more weather resistant and has more stretch to it. The Epsilon has better breathability for high output activities, and is better as a layering piece. From the description above, I'd recommend the Gamma AR since it will be better for mid-to low exertion activities, and will add some warmth in the cold conditions of N Michigan.

Best Answer Responded on

Brandon is completely correct. I own both jackets. I prefer the Epsilon, but I live in the high desert plane of New Mexico--I use the jacket year round, cool summer evenings and as a layer under a Patagonia Down Sweater in the winter. The Epsilon will be too light for the activities you describe, especially since you live in Michigan (I moved to NM from Chicago). While I LOVE the Epsilon, I recommend the Gamma AR--you certainly will be warmer. The Epsilon will be useful for fall and spring wear. Good luck!

Great climbing jacket!

Probably the best climbing jacket in the world!

Responded on

I agree. This jacket is killer for climbing and many other uses, including as a layer under an Arc'teryx shell. This jacket is the most versatile of the many jackets I own, but I live in a more fair weathered location (Santa Fe).

How does the Epsilon compare to the Gamma LT jacket?

Best Answer Responded on

The Arc'teryx Epsilon AR is more breathable, but blocks slightly less wind than the Arc'teryx Gamma LT Jacket. The Gamma LT also has more stretch and slightly better abrasion resistance. These two jackets are fairly similar in warmth.

I agree with Ronnie: this jacket is the perfect outdoor staple when the weather is less than perfect. I find that the is just the right type of protection against light wind and rain, particularly after climbing when a drizzle hits as you are heading back to your car or into a cave for cover. The jacket looks killer in town or out. I am 170 pounds, 5'11" and the medium is perfect with a layer (but not much more than than).December 8, 2009 Update: the Epsilon is a perfect ski layer above an Icebreaker 260 and under the Scorpion, and at the end of the day when you are having a Margarita at the base of the area, you can take off the Scorpion and look killer in your Epsilon. This jacket is extremely useful in multiple situations.

The Go TO!

I have this jacket in the SV which sadly backcountry doesn’t have but its an awesome jacket. I love the fit and the wrist area. The jacket is very versital and durable I have taken it every where, hunting and fishing in Alaska, skiing in Washington, BC and Colorado, climbing on Rainer every where I go this jacket comes with!

Limited versatility

I bought this shell for nordic skiing, and it works well for this purpose with only a thin, light baselayer underneath. It does a decent job blocking wind and shedding water. I usually un-zip it all the way with a cap-3 baselayer in 20 F weather when I'm really working up a sweat. I've also tried wearing it as an every-day light coat, but it fails for this purpose. It's cut too narrow to fit a sweater underneath, especially at the cuffs. In summary, nice for specific applications, but not a very versatile jacket.

Perfect lightweight softshell

For starters, if you are looking for a primary softshell jacket as a replacement for a hard-shell, this would probably not rate as a 4 star rating. This is a lightweight softshell and given that caveat, it rates as 4 stars in my book. It would gain that 5th star if it had two additional items: Pit zips and more water shedding properties. With that being said, I would guess that if one finds themselves outside only needing a lightweight softshell, the need for water repellency is perhaps moot. I've taken this cycling, skiing on bluebird days and also used as a light overcoat for everyday. The fit is close and trim, but it has excellent reach in the arms and lower no bunching/stretched fabric in the pits when hunched over the handlebars or annoying drafts in the small of my back. Given that I have broad shoulders, I am surprised at the range of movement I have in this jacket where others would leave my arms feeling constricted given the close fit. Lastly, the breathability is 1st rate in this jacket during high-aerobic activities while blocking all but the strongest winds.

My Outdoor Staple

Anytime I go out in less than perfect weather, this jacket's with me. It's light but it's warm enough for mild weather by itself. If the weather's a bit chilly it fits close to make a good mid layer.

Great jacket, but do try and shop around for a better price.

not too shabby

a decent layer, but provides no wind or wet protection. i bought this then returned it for the Arc'teryx sigma LT, which is the greatest softshell ever

Nice, but don't pay full price

Yes, I really like the jacket. I got it at the SAC price quite a while back. The feel of the outer material is a little hard to describe, and not exactly ~soft~ to the touch - kind of waffley or something, but it does move nicely with your body, and keeps the rain and wind out like nothing else. Runs pretty slim, so you can't wear a whole lot under it (6' 180 and I have the L). In the end, I'm happy with my SAC purchase, but would never pay full price for it.

Perfect fall jacket

I bought this as an in-between seasonal jacket. The fit is great, just as one would expect from Arc'Teryx. It fits longer in the back which was another plus for me. It packs down nice and small. There isn't much insulation but it wasn't designed that way. I mainly use it fly fishing, cold morning climbing and I wear it snow shoeing all the time. I wear a base layer and this jacket and I stay warm enough but it still breaths well enough while shoein'. I've worn it in snow storms and medium rains. It takes snow well but a heavy rain soaks the seams pretty quick. This is a perfect jacket when certain specifics are needed. I haven't had any complaints about wind protection. I see no difference between it and a light windbreaker. The lining is comfortable and wears well against skin. Arc'Teryx has always been worth the money.

I took this on a whirlwind tour of Europe and it performed perfectly. The material is fairly stretchy but not as much as the Gamma models. My shoulders are somewhat large for for my body size (5'7) but the large fits perfectly.

Spot on!

As a London cyclist I'd say this jacket is spot on.It enables you to go about your day without having to think about the weather all the time.
Keeps body temp.well/Wind resistant & v. comfortable. Overall serves the purpose it was designed for very well indeed.

favorite piece

Great light softshell. I find it plenty water and wind resistant. It breathes great for high output activity or for layering under goretex. For spring skiing, it's perfect with just a baselayer underneath. I've also found it great for biking and fly fishing. Just keep in mind that it has very little insulation, just slightly more than a windbreaker. Also, it is DWR treated so you need to make sure that you clean it accordingly, ie powder detergent and warm tumble dry to keep it breathable. Great product and it's stood up great for over two years.

In the Right Niche, AWESOME

OK, just so everyone knows I have a Denali, and a MH WindStopper, and Patagonia RetroX. I wasn't looking for warmth, or wind-stoppage. But, what I needed was LIGHT-WEIGHT flexible, and presentable for commuting to work (on bike). On hot days, I can put in pack. It needed to be long (it is longer in back). Needed protection from water (if I am on Ferry), or light rain. Some warmth in the fog. This Jacket WAS PERFECT. I would recommend for anyone as a jacket for the specific usage I voiced. It was my first Artyrx, and I like it a LOT!!! Great summer jacket. In winter, the Denali will come out, and the Retro. On the ridge, the MH. But, around the city, on bike, car, or hiking this is one awesome jacket.

I wish it performed as good as it looks.

I was really excited to get this jacket and thought it would be a great addition. I like the styling, fit, and feel of the jacket. As stated in other reviews it has a very athletic cut. The main thing I did not like however was when I got out into the wind. This jacket does not seem to cut the wind very well and on a chilly day this is not what you want to grab out of your closet unless you plan on layering under a windproof shell. This is the first Arcteryx product that I have been disappointed in and would not recommend. I have one of the NorthFace Apex Bionic jackets and feel like it delivers better performance at a lower cost. One last complaint is that there are no velcro cuff closures on the sleeves. Maybe I am being too hard on this jacket, but after falling in love with the arcteryx hardshells I expected this jacket to do more than just look nice.
