    Simple, light, warm.

    For less than a pound, the Rab Xenon X Hooded Insulated Jacket features 60g PrimaLoft One insulation and a helmet-compatible hood to give you a extra warmth on your next day in the alpine. Elastic cuffs help you seal this jacket around your gloves to keep out snow, and a waist-drawcord does the same thing lower down. Rab designed the YKK front zipper to go up to your nose, so you can really seal out the weather when things get nasty. Plus, this whole insulated jacket stuffs into it's own chest pocket for easy storage when the clouds clear and the wind dies down a bit. The Xenon X Hooded Jacket is there when you need it, and you won't notice the weight when it's just chillin' in your pack.

    THE go-to for both wet or dry climbs

    • Familiarity:I've put it through the wringer
    • Fit:True to size
    • Size Bought: med

    I guide in the Tetons all summer. Any day that's going to be potentially stormy, which tends to me most days up high, this is the go-to jacket for me. I love that I can put a light shell over it when it's raining and cold and not have to worry about getting it damp- unlike down products. And since it's almost as light other down jackets, and packs almost as small, it makes it an easy choice to go with this tried and true piece. I'd say I've been comfortable in this jacket (with a med weight fleece under it) in temps down to about 10*F in the Tetons.

    For how light it is, it takes an incredible amount of abuse. I've guided the Grand Teton with it over a dozen times and it's showing no signs of ware thus far.

    The pic is of me summiting Tocllarraju (19,900 feet) in Peru. It's also been by go-to jacket when I work down there. When the temps drop below 10*F, I put the Rab Neutrino down jacket over it and I'm good for temps down to -30*F. And because the Xenon is synthetic, I can put on a big down parka over it and not worry about compressing the Primaloft, it keeps it's loft even when you stack layers on top of it, unlike a down jacket would.

    Highly recommended!

    THE go-to for both wet or dry climbs

    Great weight/warmth ratio

    • Familiarity:I've used it several times
    • Fit:True to size
    • Size Bought: Medium

    Bought the ebony color (is a dark blue) in medium. To help people figuring out sizes, either this jacket is for people with long arms, or I have short arms. The medium fits my body well, it is an athletic fit so you can wear it as an under layer if it gets very cold, I've only used it above freezing. Now my arms measure to a size small, so the arms are a little longer than I would ideally want, but it isn't to the point where it's a problem.

    Tldr: super warm, super light, make sure to match your measurements with Rab's chart!

    Good, not perfect

    • Familiarity:I've used it several times
    • Fit:True to size
    • Size Bought: large

    I really like this jacket. It packs up super compact, and seems to be just the right amount of warm. I wish it had some vents for the pits, and wearing the hood looks really goofy if you're not wearing a helmet. Otherwise, it's sweet. The large is right for me.

    Great layer or stand-alone piece

    • Familiarity:I've put it through the wringer
    • Fit:True to size
    • Size Bought: medium

    Kept me warm at night up to camp II on Mercedario (10,000ft Northern Andes), and in Red Rock, Nevada with snowy conditions. When layered with a Patagonia Cap 2 and R1 below, and light MHW softshell overtop I've stayed bearably warm to the teens if I'm moving and wearing a hat/buff.

    Rab Xenon X

    • Familiarity:I've used it several times
    • Fit:True to size
    • Size Bought: Medium

    When I began my research for a jacket I debated between the Rab Xenon X and the Atom LT. In the end I decided to go with this one based on the it's status as the Editor's Choice at Outdoor Gear Lab, the fact that it did not have the fleece sides, and the chest pocket. So far the lowest temperature I've worn the jacket in was mid to low 30s and the jacket did a great job keeping me warm. I have worn the jacket in a light drizzle, nothing too wet, and it obviously kept me dry. I'll update this review later if I put it through a heavier rain. As others have mentioned the hood is ugly but is very comfortable and I'm happier to be with than without. When I was deciding on jackets I didn't think I'd use the chest pocket much but I've actually come to like this quite a bit and I now consider this a significant advantage over the Atom LT. The pocket makes it super easy to pack and throw in my bag. The fleece lining around the mouth is also a nice touch.

    The only thing I don't like about this jacket is the fine toothed zipper. While it does look good and is probably lighter than other zippers I can't help but wonder how durable it will be over the years. Time will tell and I'll update the review if I have troubles with it.

    The lack of breathable fleece on the sides is both a blessing and a curse. In cold weather when it's windy I'm covered. But because the jacket insulates well I have had to unzip from time to time to let out heat.

    Negatives: More of a personal taste but I wish the jacket were more fitted as it looks somewhat baggy on me. Unfortunate no stores in my area (Atlanta) carry the jacket as I would have liked to try different sizes to try something less baggy. More color options would also be nice.

    Chest: 40 inches

    Overall I'm very satisfied with my purchase.

    Rab Xenon X vs TNF Thermoball

    • Familiarity:I've used it several times
    • Fit:True to size

    So I initially bought a Northface Thermoball hoodie because it was so lightweight. After a few months of use, I found it to be a poor cut for my size (im tall and slim), and not that warm. The baffle stitching made the jacket breathable, but also compromised a lot of the warmth. I also found that the baffle stitching would often get pulled out and cause a whole row of baffles to come undone. So i returned that shit.

    I got myself the Rab Xenon X and it is amazing. It's so good that I am jumping on backcountry to write a review (even though I didn't buy it from them, you guys didn't have my size and colour, sorry).

    This jacket is really warm for a light synthetic insulated jacket. It isn't breathable, but for me it makes the jacket much warmer than the thermoball which is exactly what I want from this insulated shell. The cut and fit is slim and close to the body which is good if you want to throw a shell over it. It is worth mentioning that the outer pertex is substantial enough to keep out light rain. The sleeves are long enough that when you put you're reaching up they don't slide up your arms. But, you will likely find that the waist will slide up if you are reaching upwards. My only gripe is the jacket doesn't come down very far over the waist. But, it does mean the jacket works will with harnesses and backpack hipbelts. The pockets are surprisingly insulated and cosy to leave your hands in (unlike the themoball). The chest pocket is convenient especially when you are wearing a harness or a backpack. The whole jacket also packs away into the chest pocket. The hood is ugly, but very comfy. The elasticated hood trim fits my head snugly keeping wind out when fully zipped up, without any adjustment.

    I fucking love this jacket.

    P.S It also makes for a great pillow :)

    Rab Xenon X vs TNF Thermoball


    • Familiarity:I've used it several times
    • Fit:True to size
    • Size Bought: Large

    Bought this jacket as both an insulating layer and by itself. It has performed perfectly in both scenarios. Have used it under my hard shell during extreme alpine conditions and was almost too warm! Have used it hiking in very windy conditions and it was warm and very windproof. I am 6'3" and 195lbs, athletic build and the large fit perfectly. Originally bought the XL but returned it because it was too large in the torso. Awesome jacket!

    Rab & PrimaLoft

    PrimaLoft has become the benchmark in synthetic insulation and is now the go-to choice for climbers looking for static protection in extreme conditions. Here at Rab we use the highest quality PrimaLoft Gold insulation in all of our PrimaLoft products.

    The technical qualities of PrimaLoft Gold insulation are second to none. Microfibres trap body heat to make it the most thermally-efficient synthetic insulation available today, which even when wet will maintain 96% of its warmth.

    Is there a difference in the PrimalLoftGold you talk about vs what Backcountry has listed as PirmalLoftOne. Seems like a lot of retail sites list it as PirmalLoftOne and I was wondering if that's the same as Gold or a lesser/older version?

    Not quite helmet compatible.

    • Familiarity:I returned this product before using it
    • Fit:True to size
    • Size Bought: Medium

    Purchase this jacket looking for a lightweight belay /over-jacket for rock and alpine climbing.
    Good: I am 5"10, 150lbs and medium fits my torso and arms fine, both over and under an Arcteryx Alpha AR shell. It is extremely lightweight and comfortable.
    Bad: The fit over my Sirocco climbing helmet is too close. The hood pushes the helmet so firmly into my head, I'll never be able to wear it for any length of time. I have had to return a First Ascend hoody for the same reason so perhaps the helmet is the problem here. Other lower profile helmets might work better. Second issue is that the zipper is small and feels insubstantial. My first zip, I didn't have the zipper pin fully engaged with the zipper box and it slide up halfway on one side. It is difficult to engage with gloves on, and I bet with cold hands too. Hood shape is a bit like a crusader's helmet if that matters to you.

    Great and versatile jacket

    • Familiarity:I've put it through the wringer
    • Fit:True to size
    • Size Bought: M

    I have had one of these for some time now and love it. I wear it primarily in either a casual setting, but I also carry it up multipitch rock climbs quite a bit. It is lighter and as small as my rain jacket when packed, and way warmer. For a multipitch layer, i highly recommend it. I do have some cord (and duct tape...) backing up the carabiner clip loop, but only because I'm paranoid of getting it caught on something and tearing it.

    fully functional warmth

    • Familiarity:I've used it several times
    • Fit:Runs small
    • Size Bought: medium

    Let me start by saying that before I purchased this jacket/hoody, I had read reviews that actually complained about it being too warm.. let me verify that this hoody is exceptionally warm! With its Pertex Quantum and PrimaLoft One insulation this thing is extremely wind resistant and water repellent. It has a very slim fit and feels really well built. Usually I wear a large, but Rab is a little different, I wear a Medium and I am 6'1" and slim and Medium is a perfect fit. With the Xenon X's lightweight and synthetic insulation it has quickly become my favorite and go to mid layer. My one complaint with the jacket is the hood, it has a strange box stitch to it which makes it practical for skiing and snowboarding because it fits over a helmet but is very unappealing. I do really love how it fits into its own chest pocket and compresses extremely well. All in all, I highly recommend this to anyone looking for an extremely solid and warm mid layer.

    Put it like this, if this jacket were stolen or lost, I wouldn't hesitate to replace it.

    Atom LT alternative

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

    Fit, finish, and warmth seem very similar to the Arc'teryx Nuclei and Atom LT. It's super lightweight, and for that I'm not expecting durability and will primarily wear it under a hardshell. I'm 6'3" and slender; the medium fits great. Long sleeve length, good in the chest and armpits, and not too athletic-fitting...nicely trim. For what it's worth, Rab's Exodus softshell in the same size was super tight in the armpits, so the sizing is definitely different between the two Rab models. Lastly, it has a huge chest pocket, which I like. "Handwarmer pockets" aren't tricot or fleece...just the pertex with insulation.

    Hopefully it'll hold up better than the OR Havoc it's replacing. The face fabric on the inside and outside of the OR really started to wear down after one season of skiing. Not enthused...

    Customer feed back.

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

    Fit in the torso is and chest is very athletic and the hood fits amazing for being not adjustable . Sleeve cuff fit great but but fabric hangs a little long after a few wears. Lots of PrimaLoft insulation on the front but hardly any on the back.

    Best Jacket I have ever purchased

    • Familiarity:I've used it several times
    • Fit:True to size

    I have had the jacket for less than a month, but I have worn it hiking, to work, out to the bar, and also in freezing rain/sleet. It has performed well in all situations. The jacket is amazingly lightweight and compresses down to its own pocket (which I don't intend to use much), but in my gym bag I can put it in the small outer pocket usually used for accessories and pull it out in a moment's notice to get warm after I have cooled down too much outside. I did a few hours of errands jumping in and out of my car into shops and grocery stores and even when it is pretty warm inside, the jacket breathes very well, making it almost unnecessary to take the jacket off indoors if you layer lightly underneath. The warmth to weight ratio claims of the primaloft gold insulation is legit. This jacket holds in much more heat than my 300 weight Mountain Hardwear fleece. The shell is not fully windproof, but does do a good job blocking moderate wind and the finish does repel light water droppings and the jacket dries fast. However, I would still recommend an outer shell for real rain or wet snow. As for Fit; the medium fit perfectly (still allowing room for baselayer and midweight fleece underneath without being too tight). I am 5'10" 185lbs with a 41" chest, muscular arms & shoulders, and a 33" waist. I also tried the large size and it was little baggy and the length of the jacket and arms was a bit long.

    Good Jacket; not what I needed

    • Familiarity:I returned this product before using it

    I really like this jacket. I've read several favorable reviews, and I agree that for it's specified use, it's probably as good as it gets. However, I mainly use jackets for my daily winter walks, and this jacket was over-kill for me. It's a little too loose fitting, and believe it or not, a little too warm for what I needed. A small was too small, and a medium was too big, so I'm out of luck on this one. It's light weight, looks good, has a decent hood for someone who doesn't need to wear a helmet (fits close to the head to keep wind out). I returned this item and just received the North Face DNP Hoody. I haven't even had the time to "test" it around the house yet, but it's promising. I wish the Rab Xenon X had worked, but it's still a good jacket.

    perhaps the best jacket ever!

    • Familiarity:I've used it several times
    • Fit:True to size

    This is my first Rab purchase to add into my rotation and I can not be happier. How can this jacket be so light, so warm, and so comfortable. I am blown away - I have been a die hard Patagoniac for 20+ year. Well, hello Rab! Please be aware Rab has a european cut, fits slim and true to size. btw - Backcountry rocks!!!

    Quiver Killer

    • Familiarity:I've put it through the wringer
    • Fit:True to size

    I bought this jacket after I had a MB UL Down wet-out on me on a snowshoe trip. I was looking for something that was light, packable, but would hold up to nasty winter weather. The Xenon X delivers in all these aspects as well as others. To start, the materials, cut, and construction are top notch... clean, comfortable finishes around the neck and wrists and excellent articulation in the arms and hood. The large size of the napoleon pocket was a pleasant surprise as you can stash goggles or a map in there. The jacket is warm for it's weight, but don't expect it to be a furnace as my other 80/100 gram jackets are definitely warmer. If you are looking to compare this jacket with others, I'd say it's like an Arcteryx Atom LT with insulation instead of stretchy side panels, more weather resistance, and a better hood. The fit is much more refined than the boxy Patagonia Nano series and the materials are higher quality. It's one of those jackets that you'll be reaching for 90% of the time. It certainly lives up to the hype that surrounded the original Xenon.

    Update- I've now had many many days out with this jacket and it continues to be exceptional. What I've found is that the jacket provides much more protection that I was initially thinking. Several times I've been out in freezing or nasty near freezing conditions with heavy snow and wind and have grabbed this jacket. I had been fully expecting to get some protection form it and then have to add a hardshell, but I have never encountered conditions that threatened to overwhelm the jacket. This jacket is way more trustworthy than it's 14oz weight would suggest. I continue to love it.

    Simple, light, warm and good looking!

    • Familiarity:I've used it several times
    • Fit:True to size

    I have had several light down and synthetic jackets. This is the best by far! Plus, it looks good! It has a slim cut which fits slim people better than the straighter cut of Patagonia or North Face. Great in wet conditions, packs compact, and warm for the weight. In one month of use climbing and skiing it has completely replaced all my other jackets.

    OutdoorGearLab Review

    Outdoor Gear Lab's Editors Choice Award.

    This video review is for the Xenon which is an older version of the Xenon X listed here for sale. I've read that the newer Xenon X is a couple of ounces heavier due to a different shell fabric.

    Is there a difference in the PrimalLoftGold listed under the specs on Rabs site vs what Backcountry has listed here as PirmalLoftOne. Seems like a lot of retail sites list it as PirmalLoftOne and I was wondering if that's the same as Gold or a lesser/older version?

    I'm thinking of purchasing this jacket for my adult son. He is about 5'10" and 165 pounds. Would the medium be the correct size, and will it allow him to layer underneath?

    Best Answer

    I purchased the Xenon from Backcountry about two weeks ago. I am 5'9", 160 lbs, 40"" chest, and the medium fits great. I haven't yet worn it in the backcountry, but just came back from a week in the wilderness of NYC, where I wore it over a baselayer t-shirt and long-sleeve Nike thermal with plenty of room. This combination kept me warm down in the 30's with strong breezes.

    will you guys be getting anymore of these in stock, specifically Ebony in Medium? :-D

    In the picture of the jacket, the black one is shown without a hood, and looks like a different jacket. Is this a mistake, or is the black version of the Xenon X actually different?

    Best Answer

    Hi Jack,

    Sorry for the confusion- that's our bad on the picture! The Black variant is the same build that you see in the Ebony and the Ink, we'll get that all fixed up. Please do feel free to contact me with any further questions or concerns,

    Is this an updated version of the original...

    Is this an updated version of the original Xenon jacket, or is it a totally separate product?
