    Stay warm forever.

    Belay duty's never exactly fun, and it's even less exciting when you're sitting there in a blizzard for three hours while your partner searches his way up the first pitch of a rime-coated cliff. Luckily, the Rab Infinity Endurance Women's Down Jacket will protect you from the cold and snow, even during the most unpleasant belays you've ever experienced. Decked out with super-light and water-resistant Pertex Quantum GL and Pertex Endurance fabrics, the Infinity will resist moisture, but it's also been absolutely loaded up with 850-fill hydrophobic down, so you'll stay warm even if your jacket does get a little big soggy. Since the down's so lofty and the fabric's so light, the Infinity weighs just over one pound, so you'll hardly notice it's there when you're wearing it, let alone when you've packed it into its stuff sack and hidden it away in your pack.

    Lightness doesn't mean the Infinity is bare bones, though. It has all the technical features you'd expect in a big-time alpine expedition jacket, like an adjustable and helmet-compatible hood with a wire brim, an miniature baffle behind the front zipper, and elasticated cuffs and a hem drawcord to keep snow and drafts from sneaking into your downy comfort zone. Four zippered pockets give you enough room to store essentials like snacks, lip balm, and gloves, and the regular fit's roomy enough to allow for layers without drowning you in extra fabric. When you need seriously light warmth in rugged alpine conditions, the Infinity's a tough jacket to beat.

    Great Fit and very warm!

      I was on the hunt for the warmest puffy of them all. This one was a top contender! I did return it only because they didn't have the color I wanted in stock. That being said, I tried it on and the fit was great, just low enough in the back to keep your booty warm and keep the heat in. It's comfortable when fully zipped which as a petite woman, I struggle with the collar covering my nose and therefore breathing capabilities. This jacket has a separate collar from the hood which I think makes the fit much more flattering and comfortable. It also passed my warmth test in that I couldn't wear it in doors for too long! Very very warm!

      Here is another photo of the jacket's leaky seams; Rab told me this was normal.

      leaky down...continued

      To update: Rab contacted me after this post and took a second look at my jacket; after having done so, they have concluded that the down leakage is "abnormal," contrary to their original conclusion. I wish they had ruled that in the beginning, as they no longer make the black/blue color combo I loved so much. However, their level of customer service is astounding, to say the least-- they are going to let me keep the old, "leaky" jacket, and they have also sent me a new jacket, in the topaz color, for free, to use as needed throughout the winter. Since they did not have any more "subtle"/"muted" color combinations, they are additionally going to allow me to exchange the brand new replacement jacket for a new color this fall, even if I use it, all the while still being able to hold on to my old, leaky black/blue one. I must say, the customer service at RAB is like no other I've ever experienced; they blow all other guarantees out of the water. I'm relieved to know I have a jacket that will safely keep me warm during deep-winter excursions under the harshest conditions, and that I'll be able to exchange it for a more muted color once the Fall comes around. So long as it all works out as promised, I'm hoping to hold on to that new RAB for a long, long time!

      Awesome Except for Leaky Down?

      I have owned this jacket for a year, and it has kept me warm and dry while backpacking in sub-zero temperatures. It packs down to about the size of a Nalgene bottle and is very lightweight compared to other jackets on the market that aim to provide a similar level of warmth. This ranks the jacket as one of the most efficient when it comes to weight-to-warmth ratio. The Pertex Endurance coating also sheds snow, ice, and light rain well, although, while stuck between me and my backpack, the back of the jacket did get wet during strenuous trekking. The jacket comes with a hood, which at first I was hesitant about, but it really did come in handy while hanging out at night and while sleeping (I found it too warm, however, to hike in-- it's like wearing a sleeping bag on your head). The wire in the hood's brim does give the jacket added weight, but it gets the job done, especially when it's snowing heavily. I also found I can use the wire in the brim to wrap the hood securely at the back of my neck while I'm not wearing it, since the hood is not designed to roll up or detach. Finally, the jacket is slim-fitting (for a puffy), has easy-to-access oversized pockets, and has a long back length, which keeps me covered and warm. HOWEVER, the stitching along the seams of this jacket are the worst I've ever seen, and all that expensive and warm high-tech down is forever finding its way out. When I sent back to RAB USA, thinking it might be defective, they returned it to me with a message that the leaks along the seams were "normal." I cannot understand how this would be accepted as "normal" on a piece of equipment that is supposed to be so high-tech. The amount of feathers seeping through the seams of this jacket is alarming; I have never seen anything like it. It is why I refuse to rate this jacket anything over three stars; at a cost of over $400, it should not be losing its insulation so easily!

      Warmest you'll ever be on a snowy 14er

      I couldn't be happier with this jacket. It has kept me warm no matter what I'm doing. From standing watching a parade in 20 degree Temps, to taking a snack break atop a snow covered mountain with negative degree wind chill I am warm and comfortable. Don't be scared off by the price, it is so worth it!

      Like a stylish sleeping bag!

      • Height: 5'2"
      • Weight: 130lbs

      This jacket is the warmest jacket in the world! From those frigid mornings on the mountain to the cloudy cold days climbing, this jacket is key! It is lightweight, feminine, water resistant (water just rolls right off the material), and most important it is warm! I am 5'2 and 130 lbs, I went with the medium. It provides enough room to layer under but still fits in the arm length and the hips. The draw cord at the hem helps cinch it down to avoid the snow and wind and literally feels like you are in a sleeping bag! The hood is big enough to fit my ski helmet and can be adjusted in the back to fit the circumference of your head as well as around your face to prevent the hood from falling down in those windy conditions. The wire brim is ideal in shaping the hood to your specific helmet shape. I get compliments on this jacket on the hill and off. Overall, this jacket is the bomb and I can't imagine a winter without it!

      Best down jacket I have owned!

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: XS
      • Height: 5'2"
      • Weight: 100lbs

      I bought this jacket couple summers ago as it was on sale and looked pretty cool online. Little did I know, this would turn out to be the best winter gear decision I have ever made! Here's my two cents:

      1. Extremely warm - I used to suffer from complete numbness in my fingers while skiing. I didn't have numbness a single time after owning this jacket!)
      2. Very easy to layer - Its super puffy, but fits surprisingly well under ski shells)
      3. Perfect lenght - I am 5.2 and no one makes ski gear for petite women. Rab nailed it! I am very happy with the length of this coat.
      4. Lightweight - The down makes this jacket very lightweight and compressible
      5. Comfortable - Its like wearing a cloud!
      6. Stylish - I have this jacket in a shiny black. It looks super gorgeous!

      1. Wish I could roll down the hood of this jacket but there is no zipper or strap for it.

      Buy this jacket! You will not be disappointed!!

      Warm, feminine, awesome!

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

      This is a great jacket by rab - I've been on a quest to find an alpine puffy for frigid belays in the Cascades that looks vaguely feminine, and this fits the bill. I'm 5'8" 135lbs, and the small fits well over my shell. Also rare for my size, the sleeves and torso is long enough. Love the wire in the hood to stay put over helmets without feeling pinched down. Soft cloth near the neck and hands - great touches. One thing I wish it had is the ability to unzip from the bottom to free up my harness. Overall great product though - kept me warm ice climbing in 7 degrees in Cody, Wyoming, and cozy in camp in the Cascades!

      Favorite belay (and everything) parka

      • Familiarity: I've put it through the wringer
      • Fit: Runs large

      Bought this jacket because I knew I was moving to a land where winter lasts for 6 months - ended up living in it during the polar vortex in December where my state saw some of the coldest temperatures on the planet.

      It runs a bit generously, but this is alright with me, because I've been able to toss it on over pretty much anything I've been wearing. Definitely not a super form fitting puff - some gaposis around the hips and wrist gaskets - but when layered, the puffiness kind of fills in these gaps and eliminates drafts. The hip elastic closure helps, too. It's not a sloppy-big fit by any stretch of the imagination.

      The Pertex shell is surprisingly resilient for how fragile it looks and feels. Except when you get yo-yo'd by your partner into someone elses ice tools, when I learned that Tenacious Tape sticks well to it, too.

      I've turned this jacket into a daily driver: wearing it downtown, to work, as an apres-tour hut fashion statement, while belaying on -10F days in the shade, and so-on. At first I was a bit put off by the trashbag shiny, bright fuschia lined colorway (dark shark), but enough of my lady friends have oohed and aahed over it, that I'm starting to come around.

      Who am I kidding, I love ugly, bright colors.

      (5'3", 115lbs - I wear a USXS/0 in pretty much everything, went for the UK8/XS)

      Best down jacket to date!

        My Patagonia Fitz Roy hooded down jacket totally let me down. It was pretty heavy, but not very warm, and the way the hood fit was terrible. I bought the Rab Infinity with high hopes, and it did not disappoint. It's lighter than the Fitz Roy, but WAY warmer. And the hood and neck fits great. It's super comfortable. I bought it in the spring and figured I'd have to wait til fall to put it to use, but Memorial Day was unusually cold where I camped, and I got to try it out. At 24 degrees I was warm with my Infinity jacket on! I would have been cold with my old Fitz Roy. Overall this is one of the best purchases I've ever made at Backcountry.

        Outstanding warmth

          Just took the Rab Infinity out for its first spin: several days of minus 4 degree temps in Bryce Canyon, Utah. This jacket was outstanding! Tired of being cold wearing my Patagonia down sweater in sub 30 temps, I purchased this jacket based on reviews and online help. I got exactly what I was looking for: outstanding warmth in low temps,even during long lunch breaks.

          The fit is perfect. I am 5'7" and weigh 120#. I bought the size small, which fit perfectly over layers (wool tee, long-sleeve shirt, beanie and even a fleece sweater, but that was overkill). It also layered nicely under my waterproof jacket.

          Two pluses (beyond the incomparable warmth) are the handwarmer pockets and the hood. Wearing only liner gloves for picture-taking dexterity, the pockets kept my hands plenty warm. The hood fit easily over my beanie, and the elasticized edge is a nice tough, keeping the fit very comfortable and helping to hold in the heat. Also, the soft fabric near the chin was a very pleasant discovery.

          Only gripe -- the color and odd sheen. I have the Shark color, shiny and not flattering by any stretch of the imagination. But I bought the jacket for warmth, and it has delivered in spades, so I would highly recommend it for anyone whose priority is to stay warm in bitterly cold temperatures.

          Amazing and light

          • Familiarity: I've used it several times

          I bought the Shark,and took it to Everest Base Camp this fall. I would have been very sad not to have had this for night and later in the day. I also take it BC skiing as a layer to put on when we stop for lunch. I love the color and the weight.

          LOVE it!

            I took this jacket on my winter ascent to Everest Base Camp. Although it was too warm to hike in for most days, it was necessary for the bitter cold nights. It packs down incredibly small and is very light. I bought it in green and the material is so lightweight that it shows the darker feathers, so it looks dirty...that is my only complaint!

            LOVE it!

            this jacket ROCKS

              My boyfriend gave this to me as a birthday present because I'm always so cold. Living in the Northeast, it gets pretty awfully cold here in the Winters and I had trouble finding something that kept me warm enough. That being said, this jacket ROCKS. I have put it to the test wearing it while walking the dogs in below zero temps, hiking, and skiing. When the hood is on and you're all zipped up you feel like you're in a toaster oven. And the great part is the jacket is so light! I was skeptical when I first got it that it would be able to keep me warm because of it's weight but it quickly passed the test. I love that I can stay so warm without the bulk and weight of some other jackets out there. The fit is great too, stylish and true to size. I would definitely recommend this jacket!
