Tech Specs

Pertex Quantum
PrimaLoft Gold
yes, helmet-compatible
2 hand zip, 1 chest zip
Claimed Weight:
14 oz
Recommended Use:
hiking, alpine
Manufacturer Warranty:

Simple, light, warm.

Coming in at less than a pound, the Rab Xenon X Hooded Insulated Jacket features ultralight yet warm PrimaLoft Gold insulation, a packable design, and a helmet-compatible hood to give you the extra protection you need for alpine excursions. PrimaLoft Gold is comparable to down in terms of warmth and weight, but unlike down, it won't lose its insulating properties at the first sign of moisture. Pertex Quantum is light, yet durable to withstand frequent brushes with rocks, and the slim makes it easy to layer this piece under a technical shell in winter.

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 its 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.

  • Packable jacket for fast-and-light pursuits
  • Light, durable, and water-resistant fabric
  • PrimaLoft Gold for high warmth-to-weight ratio
  • Slim fit allows for easy layering
  • Stuffs into own chest pocket
  • Hood fits over or under helmet

Amazing Jacket!

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

Without a doubt this has become my “go to” warm up layer here in NH. Amazingly light, packs small and incredibly warm make it perfect for hiking. I replaced my fleece with this jacket saving weight and room in my pack. Climashield has proven its worth over and over in our cold wet environment. The pertex shell sheds light moisture. The hood, although “unique” looking is functional and warm. I use climashield now in my sleeping bag and my puffy, it’s the best insulation out there. The left zipper is different but then again so is driving on the left side of the road, you get used to it. I highly recommend this jacket.

Wow! Synthetic? Are you sure?

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

I live in the Northwest and rain seems to come at any time so down is only practical in the mountains mid summer, or the dead of winter. I have had several down jackets and many synthetic jackets. This jacket is the best of both worlds! Like other reviews stated it doesn't breathe as well as the black diamond first light hoody or the competing Patagonia version of that jacket. That said it is a MUCH warmer jacket. Over the years of Alpine climbing I have found that I rarely hike in my insulated jacket, so essentially my jacket becomes a belay parka or for when stopped and taking a break. This jacket fits that bill perfectly. It is ultra light (feels like a down jacket in hand), the DWR is excellent, still very warm when wet from rain and leaking through (not suppose to be a rain coat).
Liner is smooth which means it slides on over my Patagonia R1 perfectly. The belay zipper allows the Hem of the jacket to keep your backside warm while having good access to your belay device and harness. No more bunched up jacket between you and your ATC. I didn't realize how much I would appreciate that feature, and can't believe other brands don't add it. So over all this is by far the best synthetic jacket on the market in my opinion, especially if you run a little cold like me.
I'm 5'6" and weigh 149lbs athletic build. The small was to tight around the chest, but the sleeves on the medium allowed air to blow up sleeve (easily remedied with a little stitching to fit my dainty wrists 😀) since the slight modification this had been the best insulated jacket I've owned ever! Oh yeah I forgot to mention that after being in a down pour and water leaking through, the jacket dried out in about 45 minutes! If you have been looking at this jacket and noticed it rarely goes on sale, there is a reason for that. It's simply amazing! If in the market, buy this jacket!

Awesome review, Dan!

Thank you for the feedback.

excellent jacket for bicycling all winte

  • Size Bought: medium

I wear this jacket for several winters now in Boston. It is light and warm. I go in the snow and rain with it. I bicycle with it. Just an excellent material. Like it very much.

Go-to for synthetic insulation

I wear this under my hardshell on cold days while skiing. Also wear it on chilly fall days when I'm out on the river.

Just alright

  • Size Bought: Medium

I personally didn’t like this jacket. The fit was pretty loose and long compared to other manufacturers. However the thing that bothered me the most was warranty only covers 3 months after purchase. I contacted rab directly. My zipper stopped working ;would go up and down but not close the pocket. They suggested I took it to a luggage store.
I just don’t see or, arcteryx , Patagonia handling this , this way.
Positive. Nice style , nice hood. I won’t buy this brand despite liking the style a lot.

It's probably because there a European company and the shipping cost to ship it halfway around the world is too costly. I tried to go through a warranty clean with montane, who is also a European company. I believe the shipping would cost more than the jacket going from continent to continent. I have four rap garments that I've had for at least 5 years with no issues their quality is superb up there with Patagonia as far as dependability and quality... these big brands that people use to climb Everest and all the other highest peaks in the world need to depend on these mountaineering companies because their life depends on it , so you don't really have to worry about a warranty with these companies they're built perfectly 99% of the time.

Unanswered Question

Would you all recommend this jacket or the Arc'teryx Atom LT Hooded Insulated Jacket. I live in North Holland currently where it is quite rainy and cold, so I am looking for something for these conditions.

Very Happy

I was worried it was a little too techy looking when I first opened it but this jacket has quickly grown on me. Taken it camping on the AT and was perfect for sub 30F mornings, the hood looks a little ridiculous but is super effective at sealing heat in and makes a big difference. I just wore it in Michigan working outside all day in 24F with high winds and was astounded at how well it blocked the wind and kept me warm with a wool base layer and microfleece underneath. I kept waiting to pull out the down but never did!
The shell seems pretty thin and I worry about doing any bushwhacking in this jacket but to its credit there are no signs of wear whatsoever. packs up small and light with no effort. 6' 180 with broad chest and shoulders and large fits me perfectly, handsome cut but not too tight in the midsection.

Did I get a lemon?

  • Fit: True to size
  • Size Bought: Large

The jacket is nice, warm, and can be very comfortable if the seam under the armpit wasn’t so high up. It’s quite annoying for it to be all up on my armpit. I read that these are the same problems with the other rab jackets too. If the seam weren’t so high up, this thing is definetly a top 3 best synthetic mid layer out there

I think it is the way they cut their jackets. I had this jacket, and loved it immensely, which made that stupid quality all the more infuriating. I ultimately returned it for the Patagonia Micropuff and haven't looked back. That being said, this jacket is phenomenal in almost every other conceivable way, but I completely agree with you. Maybe Europeans don't have shoulders?

Nanopuff edit

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

This jacket is an improvement from the Patagonia Nanopuff because it doesn't have all that stitching. This creates larger air pockets in the jacket thus creating a larger thermal layer to trap body heat and warm you up. Also, the stitching squares aren't there to get snagged on things. The jacket has a little extra insulation on the front body which I am not complaining about. I have at least 3 RAB jackets and they are VERY high quality but keep in mind, they are a European company so it will have a left-handed zipper and European cut.

The best synthetic jacket

This is a great fitting warm jacket for layering

Great Piece!

  • Size Bought: Medium

If you like the Nano-puff jacket but want something that will cut the wind a little bit better then you should go with this. It comes in at the same weight and fill of insulation but since it doesn't have the stitching and is one continual piece it will stay warmer (keeping your heat in, and the wind out)
The hip pocket has a stow tag for clipping onto a harness. I'm 6' - 165lbs I went with a medium and it fits pretty well. If you want to layer more underneath you may want to go with Large.

Great Piece!

What a great jacket

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

I was leaning towards buying the new Patagonia Micro Puff hoody but got a great deal on this Rab jacket that I couldn't pass up. So far I am super impressed. The jacket feels great, packs up very small, and fits well (I'm 5'11" 185lbs athletic build and got a large). My only criticisms are that the midsection is a tad boxish and the zipper is the opposite of what I'm used to. I won't get a chance to wear it in the cold for another month or so and will try to update my review then.

Unanswered Question

What's the ballpark temperature range for this jacket?

Unanswered Question

What colour and shade (light or dark) is the interior of the Ink version of the Xenon X?

I am looking for the interior colour to be non-contrasting to the exterior colour. For the Paprika version, the interior colour seems to be bright orange, contrasting from the dark red on the exterior.

Great outer and mid layer

To continue my quest to wast.... I mean invest more money on climbing, I started ice climbing last winter. So far, I only had to sell my left kidney and what I find at home yet don't expect. But I digress.
I quickly realized I don't have a good midlayer/outerlayer jacket, because I was shivering during belaying. After asking around, I picked Xenon (not this one, I bought BackCountry exclusive one, because it was cheaper). So far, I love it and it saddens me that I have to put it away, because winter is over.
It is really light, yet surprisingly warm. Maybe too warm.
And there lies it's only fault: it's too good of insulator and not breathable.
But it's hella better than freezing.


    Rab comes through again with a smart, USABLE, versatile jacket. Quality is there too. Lightweight, more of an athletic fit (you can put light layers under it just fine); compressible in the backpack or ski bag for layering under a shell. As a layering jacket, if you find that down is just too much heat, this is your other alternative. No hybrid fabrics on sides or pits to dump heat quickly but overheating hasn't been a problem. And don't underestimate the power of Pertex Quantum as the outer ultra-lightweight fabric--very strong, wind resistant, water resistant, and helps hold in the heat.

    Used product

    • Fit: True to size

    I am disappointed that I got an used product with a lot of wrinkles on the jacket. Don't fool me this is a new jacket as I have eyes. I have bought quite a lot items here, but if we found the items defective and we still have to pay the shipment fee, thank you you guy.

    Not slim fitting as described

    • Fit: Runs large
    • Size Bought: large

    I own lots of Rab clothing as I'm 6'4" 175 and their size large fits great- long arms and an athletic fit in the midsection. If you're tall and slim u know what I'm talking about... I expected the same with this jacket but was disappointed to find the fit more "regular" and not slim fitting in the mid-section thus greatly reducing its thermal ability (I've learned my lesson with other brands). I returned it. However if you looking for a synthetic jacket, this one has been voted the #1 synthetic jacket by Outdoorgearlab for the past several years so I have no negatives against its quality/thermal ability.

    I have the same build as you and value a slim fit and long arms. What jacket did you go with instead?

    Hey Ed.p: None. I didn't find anything so I'm waiting till later this Fall (2017) and see what everyone offers. BTW, my go-to down jacket is the Eddie Bauer MicoTherm Stormdown Hooded jacket. Yea, I know what you're thinking... EB...no way. I'd say take another look at their stuff, esp their FirstAscent line of outerwear.. its legit, warm and very good quality. And they offer Tall sizes (I wear their Med Tall size for a snug fit in the body but plenty of arm length). Its the warmest jacket I've owned as the fit is perfect. Also- not sure u heard but EB will be the first manufacturer to offer a new type of down garment this Fall. The new process is such that the Down is the jacket material- no outer or inner material (I guess). Its brand new, nothing else like it on the market and EB w/b the only guys offering it for a couple of years from what I read. It w/b a game changer. I'll be watching for that when they release it.

    Unanswered Question

    Is this the new model with Active insulation or the older model with regular Primaloft Gold?

    Ebony ?

    • Familiarity: I've used it once or twice and have initial impressions
    • Size Bought: Medium

    I have lightly used the jacket so far and it seems very warm and packs down small. I did extensive research before this purchase and it seems to be all it's cracked up to be. I want to note that the color ebony looks more like dark blue. I asked several people what color it looked like to them and they all said navy blue. I always wear medium shirts and that's what size I bought. It's a nice slim fit. I wouldn't be able to wear too much underneath it.
