Alpha FL Jacket

Lining up 12 pitches in a day is a serious endeavor, and while you'd prefer to do it in perfect weather, sometimes that's not just how things go, so you need an ultra-light rain shell like the Arc'teryx Alpha FL Men's Jacket. The lightest Gore-Tex Pro jacket that Arc'teryx makes, the FL (Fast and Light, if you were wondering) is the speed demon of the climbing-and-alpinism-oriented Alpha series, with a lightweight 3-layer design, waterproof and breathable membrane, and taped critical seams to keep you dry without any extra bulk.

Unlike average shells, the FL is designed specifically with climbers in mind. It has a trim fit to eliminate any extra material, and an e3D ergonomic design that's articulated in all the right places to facilitate climbing movements The slim profile also makes it easy to see your harness, so you don't waste time and energy trying to grab piece of gear from it, while the removable HemLock foam hem inserts keep your jacket from sliding up under your harness and leaving you exposed. The helmet-compatible StormHood adjust with a single-handed pull, and the entire package stuffs into the included stuff sack and clips onto your harness with a webbing loop, making it easy to carry and quickly accessible when the clouds gather.

  • Complete protection from the weather in a lightweight package
  • 3-layer Gore-Tex fabric provides breathable, waterproof defense
  • Harness-compatible design ensures you have full range of motion
  • Regular fit has room for layers without being too baggy
  • Helmet-compatible hood doesn't compromises safety in weather
  • Item #ARC00MR

Close to perfect but short in the front

Familiarity:
I've used it once or twice and have initial impressions
Fit:
True to size

MY initial impressions of this jacket are that is a solid, no frills, lightweight jacket with one annoying design flaw. The material is light, moves well, and seems durable, although I haven't put the durability to the test yet. The fabric is a little noisy but not as bad as i though it would be. The jacket packs down fairly small and is easy to throw in a pack as insurance. My biggest complaint so far is that the front of the jacket is pretty short so the front of shirts and insulating layers stick out a couple inches below the jacket and can get wet in the rain. you can get around the issue by tucking shirts in and tightening the hem of the shell so jackets stay stuffed inside but it is still kind of annoying in an expensive jacket. I'm 6'0" 175 Lbs wearing a medium for reference. If the If the front was a little longer this jacket would be pretty close to perfect for me.

I am 5'7" 170 lbs athletic build, normal 42 jacket/34 waist and the medium is perfect fit by itself (which why I bought the FL). Love the color and how it moves with me. The neck/hood take some adjusting but work fine without a helmet. Packs down into the bag nicely for storing. Checked with CS folks on L vs M sizing and followed their advice - perfect fit.

Good jacket, but a significant difference from the SV. Lacks pockets and fabric is considerably thinner. The savings wasn't worth it. Got a medium and vs. a small based on chart. I was swimming in it. I'm 5.5' 140lbs. recommend a small with normal layering. Skip the FL and focus on the SV. More bag for you buck.

Bummer you’re not happy. If you can return for a small or XS , you should. 5’6” 150 and I love my Small Alpha FL and it’s fit though if I was wearing over just a long sleeve tee, I’d go XS

I have several Arcteryx jackets. It is the design and fit that sets them apart. You can get Gore Pro from many companies, but they don’t fit properly. Too baggy etc.... Not Arcteryx. Slim fit around the belly! Perfection! Be aware that the “Pro” fabric is noisy-“crinkly”. After a while, I don’t notice it, though. Recommend this highly

I've taken this skiing in Colorado and Vermont, up and down Tuckerman's Ravine, hiking in the Alps and the Whites, and watching my kid's soccer game in the rain. In all cases, this thing was money. It's comfortable, weatherproof, breathes well, also light, durable, weatherproof (did I say that already?), and very well designed. I had two Patagonia Super Pluma/Pluma jackets before this (and they were both great before I wore them out, except for maybe the zippers); this feels better, less stiff, lighter, and more thoughtfully sized and designed. For the price, there is no better hard shell in my opinion.

Lightweight Alpinism

The Arc'teryx Alpha FL is Arc'teryx's lightest 3L GORE Pro jacket. For those of us that count every gram that goes into our kits when we venture into the backcountry Arc'teryx delivered an ultralight and ultra waterproof shell. This jacket removes most of the features found in other jackets and opts for weight savings and overall usability. If you want an ultralight alpine jacket won't hold you back take a look at the Alpha FL.

Wow! What an awesome rain coat! I've only used it in limited capacity so far, but it fits great, feels awesome and keeps me very dry in the Arizona monsoon. I was skeptical of paying so much for a rain jacket, but I plan to have this one for a very long time. It is very lightweight, breathable and will be perfect for my upcoming trip to the Milford Track! I can't wait! Buy it!

I’ve worn this jacket as a snowboarding shell, snowshoeing, mountaineering, and ice climbing and it has not let me down. I have broad shoulders and the large fits great with a baselayer, Atom AR, or down puffy under it if needed. The large trim fit is just a little more voluminous than my medium Alpha SV which is the regular fit. The length is very similar. It is very waterproof and wind proof as advertised and breathes well. The hemlocks work quite well also. I hope it lasts for several years!

Gave as a gift but have heard some feedback. This is a super light, waterproof, VERY PACKABLE jacket. He initially used as a later during a touring session and said it was the perfect jacket for the trip. Gore waterproof seals the deal here and you can never go wrong with any Arc'teryx products.

I finally broke down and bought this for couple of years ago, and couldn’t be happier! Everything you need, and nothing you don’t. Perfectly designed. The sleeves run a little long so they stay over your gloves when your hands are above your head, the hood is easy to adjust and fits over a helmet, and just one breast pocket—perfect for a phone or a bar. The jacket breathes really well and has held up to abuse. It even has little foam pieces to help keep it tucked under a harness. It rocks! I’m 6’1”, weigh about 170 and got the size medium. I wear it over an R1 Hoody and a light top and it fits like a glove.

Agreed--nailed it again, Stan! Thanks for touching on features that are stand-outs for this lightweight, technical shell with its activity specific design.

First off, I am an athletic 242lbs at 6'3", and the Large is a great fit, but with a very thin layer underneath. I am buying the XL for those times I will need more layers underneath. I have used in significant downpours over the last two months, and the jackets is fantastic. I have yet to be let down by any of my Arc'teryx products so far. An added note, the colors displayed in the photos are not how they will appear in person. They are not as vibrant and bright...

Best shell i have ever purchased and amazing for backcountry snowboarding. Super light with only the pocket you need (be honest with yourself) great hood and packs tiny tiny so bringing it Japan was amazing. The fit is great, i'm 6' 185 and fairly muscular usually where a medium in shirts and the large is perfect. Enough room inside i can fit a down jacket under it for extra warmth but not so huge there is material flying around everywhere. I suggest this jacket to everyone who asks, which is all the time. If only it wasnt so damned expensive for so little material.

There is no better lightweight GoreTex jacket on the market. You get full Goretex Pro protection in a minimal and sleek package. I use this for everything; hiking, fly fishing, climbing, splitboarding, and mountaineering. It has withstood deluges of rain, horrible blizzards, and been with me to the summits of several mountains. The fit is a bit unique but not unlike the rest of the Alpha series, although the torso fits a bit more slim. Don't worry about not having pitzips, you don't need them. I regularly wear this on the skin track up and it breathes just fine. For the price I cannot find a better jacket and have tried many. Be aware that it is not cut for the ski resort, but if you need a four season jacket for every type of alpine adventure this is the ticket.

Arcteryx Again

My last Arcteryx jacket, a Sidewinder, is still quite waterproof after 15 years. But my new Alpha FL is everything I wanted and have come to expect from Arcteryx. It is light, no pit zips or hand warming pockets, perfect ski coat with great features. Waterproof enough for a snow day, warm enough to layer underneath. This coat will become a staple on the boat in the spring. Why did I wait so long? Nice job Arcteryx!

Swiss Army Jacket

This is my go-to for ice climbing, ski touring and as an emergency shell. It has a nice long cut which I like when I'm climbing and it wont come out the bottom of my harness. Its super simple, velcro cuffs and the hood and face coverage is amazing, especially with a helmet. I'm 5'11" and 155lbs and went with the MED. I'm super happy with the breath-ability and wind/rain protection. I'd only suggest the Alpha AR if you want a lot more thicker protection, but I use this shell more due to the need for both protection AND breath-ability.

LOOK NO FURTHER

They (Arc'teryx) definitely make THE BEST hardshells in the market. I have both the Alpha FL and the Alpha SV and love them. I have to say though that my favourite one is the Alpha FL. I work as a professional outdoor guide in the Andes of Peru and over the past years I've tried several rain jackets from different brands. The Alpha FL fits perfect, it is packable, VERY light and rough. The only downside for most will be the absence of ventilation pit zips, but if you use an adequate layering system underneath the shell you won't be clammy nor heat up as much!. Hand warmer pockets are also absent, which, unless you want to use this for wearing around town, should not be a problem. Personally, I never used the handwarmer pockets of my other jackets because when i'm on the go, I generally have my hands busy holding the hiking poles or a camera. If you tend to get cold hands easily, then just get a pair of softshell gloves + liner to have both hands warm and operating. The Alpha FL will be perfect for most people. Is good for hiking, backpacking, traveling, etc. Just get this jacket. You won't regret!. This garment is designed to be worn with a base layer plus a midweight insulated layer. If you intend to wear it using more than 2 layers underneath for freezing winter conditions, then go one size bigger than usual. If I had to choose ONLY one hardshell, this would be it! Is just perfect for any outdoor adventure where you want to have reliable potection without carrying a bulky/heavy jacket!

This is agreat jacket for several reasons: - ultra light - awesome color (Rohdei green) - good sizing (nor perfect) - great material Now, I wish you could collapse it into the chest pocket, instead you have a little bag attached that can be easily lost if you are not careful. I totally trust this jacket, at 40 miles winds and frozen rain it was a bomber. It fits a little big when using it without any layers but it's perfect on top of my fleece and my down jackets.
