Description

Down for cold-weather adventures.

Hit the mountain in fast-and-light style with the Rab Men's Infinity Down Jacket. Yup, chill-crushing 850-fill goose down. Wind is always a factor of mountaineering, and the Pertex outer shell wards off freezing breezes handily while you top out a climb or trek to the summit. Lycra in the insulated hood helps to secure it around your face, and elasticized cuffs lock out cold leaks around your wrists. Rab polished off the Infinity with a short cut and highly-packable design so it stashes into its own, included stuff sack and rides along in your day pack without eating up all the available space.

The Infinity jacket by Rab is designed to be super-light, yet very warm. This 850 European down jacket weighs only 18 oz and even has a hood. The Infinity is geared towards those who need lightweight performance without sacrificing warmth. Find out more about the Rab Infinity jacket in my video gear review.

I needed a down coat for mountaineering and this works well. Light weight, compressable, 850 down and a lot of it. Hood works very well and the elastic fabric holds it tight to your head. Collar comes up above chin height for extra protection. Feels weightless when it's on. Very pleased with the jacket. Things I don't like: shiny fabric looks a little too metro for me; so much down fill that you look quite silly with the hood up and generally look like a marshmello. That said , you're buying this for function more than fashion which is why I'm still pleased. Would have given 5 stars if the fabric was not so shiny.

Bought this to fill a key gear gap in my backcountry gear closet, and it's become a day-to-day piece as well. Great fit/cut, super cozy, and an awesome burnt orange color (Juicy). I'm 5'7", 150 and the small fit perfectly. And it packs super small -- ideal for lugging along as that extra layer.

In case anyone thinks he's kidding, he wears that jacket every day to the office... must have when it's single digits outside.

I'm 6'0'' and 155 lbs and wondering whether I need M or L. Looking at having it for a long time, so if I put on 10 or 20lbs within the next ten years what will be my best option for then and now? I know down only works when it's close to the body (plan on layering it, obviously). I always assumed large for a puffy!
Thanks

I'm 5'10", 200, with a 41" chest and a medium is too small for me in the chest and shoulders. The large fit fine. It sounds like you are completely safe in a medium, unless 100 lbs of that 155 is in between your neck and your navel.

Would this fit a tall thin dude? 6'4" 215....

Would this fit a tall thin dude? 6'4" 215. Most jackets run a bit short, does this one?

I can just barely get away with the sizing on the Patagonia Down Sweater (XL), but it's too baggy.

I wouldn't bet on it. They're cut short to fit over a harness while still giving access to the loops, so it'll probably not be long enough.

every site I have visited demonstrate variations in the color especially the blue. Your sites basic overview demonstrates a very royal blue (as do most), while individuals photos demonstrate a smoky blue. Just trying to decide on wh/ color I like prior to purchase

The cubed pillows surrounding you, and especially with the hood on, make you look like a complete buffoon. That said, you will be the warmest and least encumbered buffoon to tromp around in the sub-zero. Rab did everything they could to make this jacket light, including stretchy wrist collars instead of velcro. I would have preferred velcro. The electric orange might as well be used for highway markers, as you can spot me from space. The Pertex behaves like most other ultra-light dwr nylons. It weights nothing, and really isn't nearly as ripstop as they make you believe. I did easily tear a nice little hole in the back, but that's the trade-off for weight. I'm 5'9", 150 pounds, and the medium is roomy enough for a couple layers underneath.

I've had both the Mountain Hardware Sub Zero and Phantom. This jacket is a solid upgrade from the Phantom, and I will never look back.

Just be warned, if you put the hood on, you'll be warm, but no one will take you serious.

Warmest buffoon ever.

Anyone know the country of manufacture on the RAB Infinity down jacket. Also how would this compare with say the Western Mountaineering Hooded Flash jacket? Thanks

Mine says that it's made in China. Also, while I don't have any experience with the WM Flash Jacket the Infinity would be a much warmer jacket due to the amount of down, 7.4oz in the Infinity vs 3oz in the Flight but the Flight is also half the weight of the Infinity (if manufacturer claims are accurate). I haven't had a chance to put my Infinity on a balance but I would guess that it's under the claimed 18oz total weight for size medium, the review at the bottom says that their large only came in at 16.2 oz.

Purchased as a go between down sweater when an ultralight is not enough and a big-heavy is too much. I use this jacket throughout the winter on cold days (fly fishing, skiing, backpacking). It compresses well for its size and is light weight. The Pertex shell is amazing, brush, small flies - it doesn't tear easily. It also layers nicely and can fit under shells without much issue.

Weight, a bit heavy to lug around everyday unless you know you need the extra warmth. But a great piece to have with you when the temp drops without carrying a high altitude option. Makes a great pillow and nice to see some different color options from every other jacket on the market.

Compare its weight and size with 7+ ounces of fill to the Patagonia Dwn Sweater with 4.5 oz and I think you will find it a great alternative for deep winter use.

My size large jacket is actually only 460 grams (16.2 oz) vs. the 510 grams (18 oz) Rab gives in their specs for the same size large. Jacket has an interior pocket on a the left side and very beefy zippers on front and hand warmer pockets. Hand warmer pockets are unlined with all the down to the outside of the pocket. Down has excellent loft and the hood is loaded with down. Chin area of jacket has a micro fleece lining, about 4x5 inches on each side - which I thought was a nice touch. Very impressed with the quality. Looking forward to testing the warmth as winter approaches.
