Interstellar Jacket

Combining the best qualities of a hard shell and a soft shell, the Outdoor Research Men's Interstellar Jacket is a lightweight, air-permeable, moisture-defender that's ready to tag along on any and all alpine ascents you have planned. Crafted from a stretchy yet ultra-durable ripstop fabric, this jacket breathes exceptionally well to let you pursue high-output activities without overheating or being restricted, and features a waterproof AscentShell laminate to protect you from the wet rain, sleet, and snow that usually come with mountain adventures. Outdoor Research also made the hood helmet-compatible to take the question of sacrificing safety for comfort off the table before you leave your home. 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.

  • Hybrid shell jacket that's as protective as it is mobile
  • Stretchy, durable fabric keeps up with active comfort
  • Three-layer laminate offers waterproof, breathable protection
  • Regular fit ensures easy layering and mobility
  • Adjustable, helmet-compatible hood customizes the fit

Too thin and papery

I've used it once or twice and have initial impressions

I like O.R. but just found this jacket too thin. I didn't test the breathability but returned the jacket because I was worried about durability. So I exchanged it for a jacket in goretex active, which is a little sturdier.

Great idea poor execution. Very comfortable shell, decently breathable but way too thin and not durable at all. Wets out after a few hours, not wind proof, and tears easily. Had my cell phone in the front pocket for a 3 hour hike and it wore a small hole in it. I guess it's gore tex or nothing

Acentshell 3L fabric works in the rain

I have an older version of the Guardian jacket with the same Ascentshell 3L fabric. I can attest that it provides effective rain protection despite its seeming thinness and lightweightness. I've spent hours in steady pouring rain and never found that the fabric wets out, which is more than I can say for most other "waterproof" jackets. Its lightweight, thin construction makes it a very packable and reliable summer rain jacket. It's well constructed and the fabric works as advertised without adding unwanted weight and bulk. It has proven very durable over time despite its lightweight feel.

I love jackets that aren't even noticed when you have them in your pack. This is a jacket that should live in your pack. It is durable, 3-layer waterproof and so insanely lightweight that there is no reason why you shouldn't always have it with you. The weather in the mountains is constantly changing and it's awesome to have gear and clothing that can adapt to the weather, this jacket is one of those pieces. If it starts to rain, high force winds, gets colder. This jacket will help with all of those situations. Highly recommend.

How well would you rate the waterproofness of this piece? Can it be relied upon as a primary waterproof jacket for torrential downpours and heavy rain storms? Or is it meant to be more of a lightweight/emergency type piece?

Josh W, I came here after reading a truly in-depth review at Outdoorgearlab ( For lightweight/emergency, go with the Helium. The Interstellar is "raincoat for heavy sweaters." But read the review(s).
