2012 update is great!

The 2012 version of this jacket updated the features I didn't like on the previous models. The fit is longer, and the collar is taller. The older models fit like a belly shirt on me in the front, now it fits perfect. The collar is also said to taller, but more importantly to me it doesn't dip in the back like the old model... The knew jacket just fits like it should to me. It's a great soft shell for its niche, being just a woven fabric, but it feels tough and not too heavy. It's like a spring and cooler summer jacket, but now can be layered since it will actually be long enough to cover layers now.

Good Jacket

I got this Jacket in the fall of 11. And due the winter here in the Northeast I wore this jacket a lot. This is a great jacket for layering. If you have a CCW it pretty much makes your weapon unnoticeable, zipped up or unzipped. The main pockets are very large and easy to use when you have you pack on. Very light and rolls up easily into your pack when not needed. I do have one knock it is the the arm pocket is rather small. It would have gotten a fifth star if it wasn't for that.

Versatile alpine softshell

I've been using my Gamma LT for alpine and ice climbing over the last month in the northeast, and I'm very happy with the way it's performed. This weekend it received a nice range of conditions - hiking and snow scrambling in 5F temps on Saturday, multi pitch gully climbing and ice cragging at -10F on Sunday, and fast-paced top roping at 25F on Monday. This softshell managed my temps, sweat, wind, snow, and even running water beautifully. And it layers comfortably over my R1 hoody for a really ideal system (with 1-2 t shirts and a belay jacket).

The athletic cut is just right for layering underneath without too much excess material. Sleeve length is just right, staying just at my wrists where it belongs. The wrists have a tiny bit of stretch, but for all practical purposes are a fixed size - thankfully neither too big nor too small. The hem sits about 1" below my harness in the front and slightly lower in the back, so it doesn't interfere with anything. Collar is just tall enough to keep the wind off of my neck without restricting my head movement, even while belaying with a helmet. Pockets are completely accessible with a harness on, and will take a frozen 16cm screw just fine (be sure to cap them!). Articulation is fantastic - I haven't felt the least bit restricted even during the highest reaches. Wouldn't trade it for any other soft or hard shell, including my Alpha SV which is now collecting dust.

Not for me

Let me start off by saying, I'm sure this jacket is good for what it's designed for, just doesn't seem like much else. The material feels durable, to the point of being a touch itchy against bare skin on the inside. It's not at all wind proof but fairly resistant. I wore it sailing, and while working it kept me warm with just a cap 2 base layer in the 50's. Managed to shed splashes fine too.
My issue is the fit. It is really short in the front but more than adequately long in the back. Think atom lt length in the rear but shorter in the front. This combined with the tight fight and low collar make it tough to layer with anything more than base layers. Just not sure what to do with it, since it's not insulated at all and can't accommodate much layers without hem sticking out a ton in the front.

hey scott, may I know your chest and height measurement? I am S in Beta AR, Alpha SV, and Sidewinder AR, and curious what size this softshell should be if I want to layer it with a Thermal Pro fleece inside. Brandon are you there? for reference I am 5'7", around 37.5" chest. Thanks!

Responded on

sorry I meant 38" chest. Thanks!

great jacket!

such a great all around jacket, throw a fleece under it when it gets chilly, breaths great, repels water like a champ, fits like a glove(and a well fitting one at the) im 6' and 168 lbs, and wear a M. couldn't ask any more from it!

Good purchase

Got this jacket last month and was in a quandary on sizing. Have the mx in L...and it fits pretty well, but just a bit loose. After much deliberation I went with the medium. Nice trim fit...enough room for a baselayer or thin mid weight layer...but nothing else. I'm 5'11" 180lbs. Wore the jacket hiking and climbing in the 20 - 30's and was comfortable when moving. If I had to sit around at a belay for a long time in those temps it might get cold, but I usually have a puffy vest. I think this jacket is going to excel in the higher output activities down to the 20's.

Daily dose of Arc'teryx

I picked the Gamma LT up as an impulse purchase. It was 45% off and as an Arc'teryx addict I couldn't pass that up. I haven't regretted it one bit. It's now my daily jacket and it works great on the trails and in the bar. The titanium color is very sharp and I love the little detail of the green zipper. We all need a little bright color in our life.

Performance wise it's an incredibly versatile piece. Hiking, snowshoeing, around town, I've had no complaints. I've even used it as a cycling jacket when I've forgotten my Pearl Izumi jacket. I've yet to feel clammy and wind is rarely a problem, nothing a good fleece underneath can't cure. I've actually had a couple of people sprinkle water on me while wearing it because they love watching the DWR finish in action.

Looking for some size advice here. I have a Gamma MX in L and it fits pretty well, but a little on the large side...definitely room for layering. Wondering if the M would work better for this piece. I'm 5'11" and about 180lbs. Pretty fit, but not exactly "ripped"....

Responded on

You're a classic Medium for pretty much any Arc'teryx gear.

Responded on

Got to break my jacket in this past weekend. Hike a mountain and did some rock climbing in WV. It worked really well in the chilly morning hiking....25 degrees, with a l/s wool baselayer and range of motion was good for the climbing. The medium worked out well since I didn't wear anything too thick, and I could throw a puffy vest over it if it got any colder.

Perfect Fit

I was looking for something to get me from A to B in downtown Denver where I live, as well as a shell that could help keep me cycling further into the year when I came across this product. The price tag was a bit steep, but every review I've seen seems to rank Arc'teryx among the top "activewear" manufacturers, so I gave it a shot. I just got the jacket in today and am THOROUGHLY impressed. Here's a few early highlights:

-I'm 6'3" and a trim 180 lbs, which makes fitting into clothes generally a chore. The large Titanium fits me SO well, I may have to look to Arc'teryx for regular clothing!
-The material is snug but stretchy and allows for a surprising range of motion.
-The pockets are ingenious for easy-to-reach accessibility.
-The outermost layer seems pretty water resistant, and looks designed to cut some wind as well, while at the same time, this thing breathes like it has lungs of its own.
-Did I mention the shell looks awesome!?

One thing that potential buyers should know is this: the Gamma LT is not designed to keep you warm in cold conditions, nor does it have a hood. It's pretty thin, and essentially feels like one of the nicest rain/wind coat you could generally get your hands on. However, it's fit to layer underneath other shells, which would help with warmth immensely.

Really, only time will tell on this piece, but I've got a feeling this first purchase will have me hooked on Arc'teryx for a long time.

Responded on

UPDATE: It's officially been one week since I got this in the mail, and I'm convinced it's the nicest light jacket I've ever owned. It is very water resistent (heavily tested during a rainy weekend) and actually cuts wind as well. I was able to get to class comfortably in the mornings wearing that coat over a t-shirt with the temperature in the high 40s/low 50s and gusting winds. For anyone on the fence about this jacket--check your size with the sizing chart and try this thing out. If your purchase is anything like mine, the last thing on your mind will be returning it!

Posted on

I don't quite get it. This jacket has no hand pockets and is literally a shell, as there is zero insulation. For such a price, what does it do? If it doesn't have hand pockets or insulation, it may as well be a really nice base layer. What am I missing about this product that justifies both the cost and reviews?

Thanks for any feedback

This jacket is a softshell jacket made by Arc Teryx. Most Arc Teryx products are well designed and high priced (so it is on the higher price scale for softshell jackets). The jacket does have hand pockets (they are the front pockets) that are slightly higher on the jacket so they are accessible when you have backpack with a hip belt on.

The jacket is not designed to be a base layer or an insulating layer. It is a highly breathable, windproof, jacket that will be best in snow or light rain designed for cool weather aerobic activities. It's a versatile jacket.

Green zipper. Looks really sharp. It's actually the reason I picked the titanium over the black or deep dusk. Everyone needs a little splash of color.

I'm looking for something to bridge the gap between my Arc'Teryx Atom LT and my Beta AR for spring and fall seasons. I'd like it to be fairly water resistant, but it doesnt have to be too warm (ex, dont really want a fleece). This seems to be a good match, but does anyone have other suggestions?

Responded on

Hey Tyler- The Gamma LT is exactly what you want, but if you don't mind waiting Arc'teryx has a new jacket called the Acto MX (both jacket and hoody) which I think would suit you much better. Its not on BC yet, but will be soon I imagine. Heres a pic of it:

Gamma LT

The Gamma LT is a light weight softshell that uses very adaptable textile material that takes the role of a second skin. It is extremely breathable, sheds moderate rain easily, and resists all but the most powerful gusts of wind. This was my first step into the world of softshells and it is alo my first Arc'teryx product. This jacket does not include a laminate, which is the genius in the design of this piece. I own a gtx shell that is impenetrable (both windproof and water proof) but this softshell picks up where other softshells drop the ball, because it has not laminate it is EXTREMELY breathable. By no means should this softshell be an end all, there is a time and place for complete waterproofing and windproofing, but in the city this unlined shell has handled everything I have put it through. I hope to really test the piece in the backcountry this summer, and I plan to make it my go to jacket for everything except torrential downpours. I am 5'10" 170lbs and the medium fits PERFECTLY. The size is also roomy enough to fit a fleece under it on chilly days. Overall, I am glad to get a softshell that is the perfect medium, it combines reasonable features such as wind resistance, water resistance and amazing breathability, with superior comfort, fit, great stretchiness and a sleek look to make an amazing softshell.

Question rco. What color is the jacket you posted. It looks like the Titanium color, but the titanium in the picture has a green zipper and black shoulder pocket, neither of which I like. I was looking for a jacket exactly like the one you posted...all gray.

That is the deep dusk colorway it is a little light in the picture but it is more gray than the online shot looks

How would this compare to the Mountain Hardwear Synchro Jacket in terms of water and wind resistance? I'm looking for a light softshell to wear on chilly/windy crag days and camp nights, it doesn't have to endure any harsh conditons.

Best Answer Responded on

This particular jacket is quite different from the MH Syncro. The Gamma LT jacket is a stretch woven construction, with no membrane, so it's way more breathable and stretchy, but doesn't offer as much weather protection. A better comp would be the Arc'teryx Venta AR or SV, both of which are Windstopper. Or, my favorite, because it fits in between these, is the Gamma MX. Lots of reviews on that page to inform your decision.

The perfect warm weather jacket

Loving this jacket! Bought it as a general spring summer autumn active jacket. It was my first soft-shell so didn't know what to expect. I now find I wear it doing pretty much anything from warmer Feb days in the uk, right through until the temps drops in late November. It's just wind proof enough to stop most breezes, and those that get through seam to help the breathing and stop things getting stale.

It's got no noticeable thermal properties, but it's strengths are in providing a barrier without stopping breathing. I wear it hiking in pretty much anything except the warmest of days, relegating the goretex shell to the pack until it really throws it down. It even does it as a cycling shell through the winter.

And to op it all it looks great. i'm 5'9" and 80 kgs (170lbs?) and a medium is perfect.

This is one of m favorite Arcteryx pieces. It is a little roomier than my epsilon AR but still fits great. It resists wind well and has fared well temperatures in the 30's with just a t-shirt underneath. I am 5'9 and 170. I wear smalls in all of the technical waterproof shells but have found the medium in their soft shells and fleeces to fit well. I have a medium in this jacket and it was a great choice. A great jacket for around town and will easily go over any clothing since it doesn't have a fleece liner. GET IT!

Almost a hard shell

Great piece to be used in the mountains or around town. The fit is great with an athletic style, and I like the long back and shorter waist. Great mobility for climbing, hiking, and I've used it on commutes on my road bike. I've worn it in some steady downpours with it keeping me dry. The weather resistance is sweet..... It sheds rain like a champ. Windy days are no problem at all just as long as the temp not to cold. Breaths well when your putting out some hard efforts. Another great tech piece from Arcteryx.

I am 5'10" 175lbs with reasonably broad shoulders. I wear a 32/33+ length sleeve when I buy a button down shirt. The sleeves on this jacket are fine, but both the Medium and Large would fit if you wear 34/35 sleeve shirts. The M is perfect with a longsleeved shirt with a Tee Shirt over. The L probably fit me better on the torso bc it gave a bit more room for layering, but the L was quite a bit longer in the torso. To the point where it looked funny. The sleeves were not much different at all btw the M and L. If you are btw 5'11" and 6'2" and weigh 175 to 215 get a large or bigger.

Simply Awesome!!

I am very happy with my purchase! I bought the everglade color and all I can say is that I am very impressed.

It has an athletic cut to it which means its going to be fitting more close to your body but you surprisingly still have room to move around freely. This jacket may seem a little pricey but it is most definitely worth it. Highly recommended!
