The Outdoor Research Men's Interstellar Jacket is a lightweight, air-permeable shell ready to tag along on any and all alpine ascents you have planned. Crafted from a stretchy, durable ripstop fabric, this jacket breathes exceptionally well to let you pursue high-output activities without overheating or being restricted, and it features a waterproof AscentShell laminate to protect you from the wet rain, sleet, and snow that usually come with mountain adventures.

Dynamic reach underarm panels enable mobility when you're stuck on the wall, and the pockets are situated above where your harness would go to meet the needs of any alpine expedition.

Sturdy shell when things go to hell
Before buying the OR Interstellar jacket I did my homework. I was planning a summit attempt of Cotopaxi in Ecuador, but I didn't have an Arcteryx budget. Upon first glance, the jacket was medium in its structure, light in weight, had a great hood that fit my helmet with great articulation, and the jacket had a nice trim fit that accommodated layers underneath yet fit nicely under my summit parka. I chose training days of driving rain/sleet and it held solid, I took the jacket up cold ascent to see how it would breathe at high output and it performed great. Though pit zips would be nice, it wasn't a problem. Then came the true judgement day.... The night we left the hut for the summit of Cotopaxi, the weather was horrible! There was a 40mph wind, freezing drizzle/rime ice, and my first line of defense was this jacket. Though any fabric had its limitations, this jacket performed flawless. When the gear of my teammates was failing, I was DRY in my interstellar jacket. We were forced to turn around at 18K ft and I was still DRY when my team arrived back at the hut. In the worst conditions possible, my OR Interstellar Jacket exceeded my expectation. I'd happily recommend this jacket as a rain jacket or light mountaineering hardshell. Super happy with this jacket! Picture: 18,000 ft, covered in ice on Cotopaxi

Top Notch Breathability
Of the many waterproof and windproof shell's I've tried, this is the most breathable. If you need protection from the elements, but plan to sweat while you're exploring, this thing is the way to go. I don't tend to wear out gear as quickly as a lot of people do, but to me the durability has proved sufficient for climbing and backpacking in adverse conditions. The hood is also really easy to adjust to either your head or a helmet, and moves well with you when you turn your head.

Superb light and breathable rain shell
The Outdoor Interstellar jacket kept me dry on a 2 day backcountry trip in the North Cascades where it was raining the entire time. I have also been happy using it in place of my softshell jacket for hiking and other activities. It is extremely breathable and I have had no issue with perspiration building up with my jacket fully zipped up. Hood functions well and would fit well over a climbing helmet. Jacket runs a little small which I prefer for a more fitted look but felt comfortable wearing it over a couple layers.

Allen, thanks so much for leaving that review, we always appreciate feedback! Happy the Outdoor Research Interstellar Jacket worked out well for you!

Lightweight, Tough, Packable! What else do ya need? This shell has handled some very stormy weather. Great so far for backcountry adventures. No pit zips, but I had no problem with that, this sheds heat awfully well. The medium is perfect for me with layering. This thing feels tough too -3-layer AscentShell waterproof laminate at only 11.6 ounces.

This jacket can be used for many different activities which is awesome. I love the Ascent shell material because it is very breathable and stretchy, regulates your temperature well while moving, yet is waterproof. I use this jacket for touring, hiking, and climbing. I love how lightweight it is at 11.6oz making it super easy to stash in a pack. The placement of pockets is nice when wearing a harness. Armpit vents could be a good option in the future to cool down more when working very hard. I would recommend this jacket. I am 6'0 175 and a size large fits me well.

Great Shell - but not for skiing...
I've had this jacket for roughly 8 months. Primarily used for ski touring. Also used once for mountain biking. Breathability is great and the jacket is lightweight and packs small. The result of those pros is that it is very thin and fragile. I have already put three large tears in about 20 days of use from ski touring. Also holds onto dirt. Washed multiple times with specific cleaner to remove dirt without any luck at all. Just washed away the waterproof coating... Great jacket overall, but definitely not for ski touring. P.S. I put this same review on the OR site and it was never posted. Just thought I should mention this...

Hey William, yes, it is lightweight and isn't built for durability. Did you catch some trees? I will look into the post on the OR site. I know they went through some updates and wondering if they had issues from that... Thanks for the heads up. Leta OR Rep

Hi Leta. I have brushed some trees, as I have with all my other shells - it is inevitable with backcountry skiing. Goretex Pro and Active shells have held up to years of the same, but this one only months. The OR rep I spoke with over email told me this would be a great shell for ski touring.

Lightweight hardshell is nearly perfect
The OR Interstellar is a very good hardshell - I picked it up this winter to replace a 3L Mammut Gore-Tex Paclite and have used it for inbounds skiiing, touring, and summiting Mt. Washington. The Interstellar shaves quite a bit of weight from traditional 3L shells, but still kept me well protected on Mt Washington where the summit temperature was -21 degrees Fahrenheit, with windchill in the -65 range. It also fits well with a clean athletic shape but just enough room to layer a wool baselayer, an R1 hoody, and a Nano-Air/Atom/Proton softshell insulation layer without compressing the insulation. Bonus for the easily adjusted, well-fitting hood, and the three external pockets - one Napoleon and two handwarmer pockets. I do think it would be improved with pit zips, and I find the front zipper to have too much resistance as it passes over the neck, so one star off for that. Overall an impressive piece that likely gives up a little durability against heavier hardshells but really works as you would expect a performance hardshell to work.

Really great review, Christian, thank you. The pit zips comment is challenging because the goal is light weight and packability, both are negatively affected w pit zips. Thanks so much! Leta OR Rep

Close but not quite
The stretch, the price, and the weight are very good! I'm 5'10", 170lbs, and typically wear medium or large tops and large bottoms. I tried the Interstellar in a medium and it fit well except for the hips. The hem was too tight and I would not be able to start the zipper if I was wearing ski bibs or a midlayer. I also found the hand pockets to be too low for wearing a backpack.

The interstellar jacket is magical. Usually, shells sacrifice either breathability or weather resistance for the other. Somehow, Outdoor Research has managed to make this jacket light, breathable, windproof, AND waterproof. Definitely the best jacket purchase I've made in a while. Heads up: the outer membrane will become saturated and you will look

Seems decent, but not a great fit
I ordered a few rain jackets to hedge my bets and this one didn't make the cut. Main reason came down to fit- the bottom hem seemed too tight, even with the tensioners loosened all the way. The sleeves were plenty long and shoulders fit well, but I could see this being hard to layer under, as there wasn't enough stretch to make up for the hip tightness.

Thanks Nick! What jacket did you end up going with?
May 25, 2018
Hey Nick, so sorry! This Interstellar is a trim fit, but I will ask out product folks to look at the cut. Great news about Interstellar is that it won Gear of the Year!! Sorry it didn't work out for you! Leta OR Rep

I agree that the current iteration of interstellar is more trim in the body. And it actually worked better for me than many other jackets on the market, so I have got it in Solaria color for my bike commuting.

FIRST IMPRESSION: The Interstellar Jacket is LIGHT! I really like the athletic fit and minimalist design of this shell. It's trim, with a perfect waist length to tuck under a harness. The sleeves are long enough to cover the back of my hands. The fully zipped collar completely covers my neck and chin. The hood fits over my climbing and backcountry ski helmets. The fit is definitely DIALED! My only dislike are the partially elasticized wrist enclosures. I think there are more functional and durable enclosure choices for this type of jacket. I was concerned the Interstellar jacket was going to be just another frail and anemic offering currently popular in the climbing and backcountry skiing shell markets. Boy was I wrong. The Interstellar is LIGHT (<12 oz), stretchy and the 3-layer AscentShell appears very durable and abrasion resistant. Imagine if the Helium ll and Ferrosi hoodys had a love child. This is the Interstellar! IN THE FIELD: I took the Interstellar on it's first mission yesterday. We backcountry toured from the Sugarbowl ski area to the backside of Mount Judah in search of Spring corn snow. Temps at the parking lot were cold (28 degrees) and clear. I layered the jacket over a thin base layer and threw a mid-layer in my pack. That 2-layer system was perfect for the ascent in cold temps. Not once did I have to think about venting or adding/removing layers. Once on top we traversed the ridge to our intended ski line in howling winds. I flipped the Interstellar hood up and cinched it down tight. On the leeward side we found full sun, no wind, and PERFECT corn snow conditions! Amazing turns ensued. On the skin back up I intentionally kept the Interstellar on and zipped tight. In the full sun I could feel the warmth being generated from my core, but I never really broke a sweat. I had to vent my Patagonia Refugitive goretex pants, but the AscentShell breathed like a champ! The Interstellar jacket will fit perfectly into my 3-jacket quiver, between the Powslayer and Helium II. It's a full value 3-season shell, with fast & light 4th season applications. I plan on using it all Summer for backcountry skiing and climbing in the Sierra, and taking it with me on a trip to Iceland and Norway in September. The Interstellar is one impressive jacket Outdoor Research!
