Stay warm when you play in the mountains.

The Rab Men's Infinity Endurance Down Jacket provides lofty warmth whether you're making an ascent on a snow-capped mountain, belaying your friend on a freezing ledge, or just chilling around a campfire at night. This jacket's Pertex Quantum GL fabric helps keep it super light, and its Pertex Endurance coating makes the Infinity Endurance windproof, breathable, and highly water resistant. Insulated with 210 grams of 850-fill power, hydrophobic European goose down, this jacket is extremely lofty, very warm, and extremely light for the heat it produces.

The Infinity Endurance has a huge hood that you can adjust to cinch down tight over your head when it's windy, or you can loosen it up to make room for a climbing helmet. It also has a wire brim to give the hood nice and sturdy protection from sunlight and falling debris. This jacket has elasticize cuffs and 2 drawcords at both sides of the hem so you can prevent any unwanted winds from blowing up in it. Rab included a stuff sack for this highly-compressible jacket so you can take it with you anywhere whether you're concerned about space or not.

yet another quality product from RAB

  • Familiarity:I gave it as a gift but have feedback to share
  • Fit:True to size

I bought this jacket for my dad for Christmas to replace his old Mountain Hardware Kelvinator, which he was never extremely happy with (he wore it on our climb up Mt. Rainier last summer and was upset with how poorly it performed in windy conditions). The Infinity has really good quality, water repellent down which makes it warm and practical in harsh environments--perfect for his mountaineering pursuits. The hood is helmet compatible, which is a huge plus for climbing or skiing, and the jacket compresses really nicely as well. Not only is the Infinity perfect for spending time in the mountains, but it also looks great and is an awesome jacket for casual wear around town.

THE VERDICT: Dad loves it, daughter is jealous. You should probably buy this jacket.



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

Probably the best ~20 oz down jacket. Love it!


Darn Fine

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

I tried on all the high end down coats at the Backcountry warehouse just west of SLC, UT ( very patient and friendly employees there). The Rab fit me the best, had excellent loft/warmth and very usable cut for everything from loafing to work to needing it camping. I'm not saying that it is solely an inferno; I've been impressed how comfortable it is up to about 50 degrees. Walking around a store in the winter with the front open is pretty comfortable.

It does well as a packable near infinite barrier to the cold. I got stuck on some hot springs and didn't really have a torso underlayer to walk the 7 miles to the car after dark and -5 degrees F. I just put up the hood and sinched the waist. The wind was a little chilly at times but I felt fine generally. It saved many parts of my body that day, most especially my a**.

Does the infinity have the same feature as the Neutrino Endurance to be able to strap down the hood when you are not using it? Besides the front pocket what are the differences between the two models? Thanks

I don't think you can strap down the hood on it.

Hey Aja- The Neutrino is a warmer jacket, and it runs a little longer,

but both are simply outstanding jackets, I own both models and am very happy with them. I would say you could wear the Infinity down to 25 degrees(without a layer), and the Neutrino lower than that. They are both very warm though. I got one as a X-mas gift and decided to hold onto it. You'll be well served with either coat, you'll just need to layer up a bit more with the Infinity Model.

the picture makes it look like either the sleeves are long or the waist is short. Does anyone have a comment on fit?

Best Answer

I have found that the sleeves are unusually long which makes me consider returning it. Additionally, a previous commentator stated that the down was NOT hydrophobic, which is counter to what the product manufacturer states on its website. So either he knows something that he is privy to or he is misinformed......

sleeves are long which works for me (36" sleeve) but also work well for reaching. Hydrophobic coating on down was added in current model year, older models/colors will have regular down.

Is the down in the Infinity Endurance...

Is the down in the Infinity Endurance hydrophobic? Is hydrophobic down water resistant?

The down in this Jacket is not Hydrophobic, which usually means that the manufacturer has coated the down with a special coating that makes the down resistant to absorbing water. This jacket does have a Pertex shell though, which is a water resistant fabric, so you can wear this in wettish conditions and it should shed water for a bit.

Have recently purchased this jacket, I am now concerned as to whether or not this jacket does have hydrophobic goose down or not. According to the Rab website and the tags attached to my jacket, it does have hydrophobic down....yes or no?

Best Answer

According to every piece of marketing for this jacket, it does indeed have hydrophobic down. People who are saying it doesn't may be getting it confused with the regular Rab Infinity (not Endurance) model which does not. That was one of the several improvements in the Endurance model.

It depends on the model year-their current models have the coated down while the previous years were just regular down.

If the tag mentioned it - it sounds like a pretty sure bet.
