Arc'teryx Epsilon AR Jacket Reviews:

Positive Reviews:

Prior to buying this jacket I searched multiple sites looking for reviews but could only find reviews of the last model...thus I'll review this one.This jacket is ideal for weather between 50 and 65 degrees, maybe cooler if you're layering underneath. It's very breathable and wind resistant but by no means windproof. It repels water really well but with prolonged exposure h2o will bleed through. I ran in a light rain in 50'ish degree weather this spring with the jacket on and it kept me dry and appropriately cool, i.e. a great job.The fit is perfect. I"v read reviews on the previous version that it is short and snug fitting. This is not a snug jacket but is streamlined and is a good athletic fit. I'm 6'3 195, athletic build and was worried this wouldn't be long enough. The length though is just right, hitting just below the waist in the front. The back hits a bit lower. The sleeves are plenty long and the elastic around the wrists is soft and not too tight so I can easily get in and out. The arm pocket, although cool stylistically, is useful for chapstick, maybe a protein bar, but really nothing larger than that. The reflective archaeopteryx is sweet but would have preferred an embroidered one. The chest pockets are roomy but sit a little too high for comfortably having your hands in your pockets. A slanted pocket may have been better.Finally, the reason for the 4 stars rather than 5 (if I could, I'd give 4.5 stars), is the interior lining. It's a bit scratchy and by a bit I really mean a bit, like a 1 on a scale of 1-10. My wife has the Epsilon SV, which has a microfleece lining (a slightly cooler weather jacket) that is super soft and makes me wish they had a similar lining for the AR jacket. I'm being picky but hopefully helpful.Overall, I like this jacket a ton. I have a North Face Apex Bionic, which has the soft inner lining and is a warmer jacket, as well as windproof, and I like the Arc'teryx better simply b/c the material is way more flexible.

The Epsilon AR jacket is a nifty little piece of kit that is always a joy to throw over my shoulders. I'll first say this piece is more of a "nice to have" than a must have if your adventures go beyond day hiking or a walk in the park. This piece just seems better suited for casual day to day wear. Now that doesn't mean with the right combination of layering/conditions it couldn't be useful for someone, but lets be honest...
With that intended use in mind, I was still inclined to pick this up albeit at a discounted price. I have other shells for real excursions, but this really nails it for around town wear. I love the styling and the hard fleece material cuts just enough out of the wind and knocks the edge off the chill. Hardly a warm insulating jacket. It provides enough protection from the elements to get you there, and is comfortable enough to wear inside as well.
What I liked about this piece is it still retains some technical features which allow it to come with you should your day end up at the crag. I'm particularly fond of the drop tail cut of the jacket. The fit is athletic and well fitted.
In typical fashion the workmanship is what you'd expect with Arc'teryx - Flawless. The material seems burly enough that you're not going to destroy your around town jacket should you sneak in a few pitches on your way home from school/work.
Great product, but remember it's purpose before expecting it to be something it was never intended.

Surprisingly warm, Very nice overall

Very nice lightweight softshell for spring/fall layering. It's surprisingly warm for its thinness and non-insulated nature. I've had other softshells (the Mtn Hardware Onata in particular) that are also thin but completely useless and provide zero warmth or wind protection. Granted, this piece is at least 2x more expensive, but definitely worth it.

The moderate warmth combined with being highly breathable allows it to comfortably adapt from mid-low to very-high output activities while keeping you dry and comfortable. It's not the most wind resistant, but would be good protection for all but the stronger winds when you ought to be wearing a hard shell anyway.

The hand pockets are thin, but they work. The arm pocket is especially useful. I've always liked Arcteryx cuff construction and this one is also great - a bit different with the offset hem but functional. Fit is not tight but technical. Some room for layering underneath (an atom LT fits under but it's a bit compressed - oddly it works quite well to layer an atom LT *over* the Epsilon AR if you're not being rained on)

Exceptional Jacket

I bought this jacket to wear on runs when it is windy around the Sound. The trick is most wind resistant jackets are either not resistant enough or do not breathe leaving you drowning you in your own sweat.

I looked at many jackets and walked away with this one knowing I'd spent more than I would on the competition. I am glad I did - this jacket breathes very well and doesn't let the wind cut through you like some others I've worn. I suspect this will be a great early spring / late fall hiking jacket as well and look forward to testing it out.

The fit is nice and snug which for running is what I was looking for. The inner layer does indeed wick well as advertised. The only "complaint" is that sizes seem to run big - I'm 6'2" and ended up in a medium when I usually wear large. The length is appropriate for my height.
Jeff the Runner at REI on 04/04/2010

This jacket is one of the least used that I own. There is really nothing special about this jacket except that it looks great and can hold off some light moisture. My Epsilon AR doesn't get used very much because I have other jackets that do a better job of keeping out wind/moisture that are even lighter than this jacket. But If I want to look good at casual events, I usually bring this jacket along.
The two mesh pockets on the inside are huge! I could probably fit 2 footlong meatball sandwiches in these pockets (they would be nicely squished though). I usually keep my keys or my cellphone (small Nokia) in the arm pocket. If you are looking for a very simple, nice looking, nice fabric jacket than this might be the jacket you should get.

Great breathable tough softshell

Love this jacket (2009 edition). I've had it for a few months now and have been super impressed. To start, the jacket breathes very well. I use it for skinning uphill in the backcountry and for winter peak bagging. The jacket also has a great finish and water beads up and rolls off beautifully, although it will wet out in the rain. Construction quality is superb and durability is solid. This jacket is a jack-of-all-trades as it works is a wide range of temps and conditions. Nit picks, the sleeves don't have a cuff so they will slide down as far as the length allows. If they moved the pockets back to the chest and added a hood it would be perfect.

What a jacket. Lightweight, very water resistant, very wind resistant (20-30 mph), great fit, asolutely dig the orange color, no cons whatsoever. After roughly twenty-four combined hours of hiking in dry conditions, light rains and moderate snows, the water still beads, and the pits smell like the outdoors. Size L fits 6' 2" 205lb frame perfectly with great range of motion. Makes me sad I have so many other great fleece and lightweight jackets, cause now they are going to sit in the closet as backups. I'm sure they will get over it...

I can see why reviewers would describe this as "gutless" or "nothing to it" and as their "fav." While I'm not sure what technical niche it fits, it feels and looks great. The fabric drapes really well and moves with your body, and it simply looks good. So while I only wear it around town, I'm happy every time I put it on. It'll keep the weather at bay but I wouldn't expect "too much" of it. It's just a comfortable, good-looking, functional jacket.

Great design

It was time for me to find a new soft shell and re-vamp my layering system. I chose this jacket because I really liked the fact that there aren't lots of extras on the jacket. It is simple, but well thought out. I really like the tapered and offset sleeves. The jacket fits great and does not get in the way of my gloves or get snagged on anything. And the fit is excellent for a guy who is 6'5" with long arms.

Everything and More

Unfortunately, circumstances won't allow to live in this jacket, but as far as possible that's exactly what I do. I find myself looking forward to inclimate weather just so I can test the range of it, and so far so good. Thoughtfully designed, and flawlessly manufactured this garment is virtually seamless, and the only drawback to owning the jacket is that my other jackets come up short by comparison.

Negative Reviews:

After receiving this jacket in the mail, I was unimpressed with the material on the inside. The outside fabric seems durable enough, but the inside doesn't seem useful for anything. It is not fleecy feeling at all, in fact it just feels like scratchy nylon. There doesn't seem to be any insulative properties to it at all, beyond blocking some of the wind I guess.

Neutral Reviews:

I ordered this jacket for my husband as a layer under his Theta-AR-something shell, and when it came, it was basically another "jacket", not something warm for underneath a shell, even though the description said microfleece and "layering". It was really nice, cool color, and cut - but like many Arcteryx jackets, there was nothing to it, in the Northeast, I would freeze in it! So I sent it back for more of a fleece.
