    Perfect on the go rain jacket!

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

    I bring this jacket everywhere in the summer! It is super lightweight and compacts pretty small so I transfer it amongst my different packs. I use it for hiking, biking, and around town. Despite its lightweight, it has kept me super warm and dry all summer!

    Backpacking in Washington

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

    I bought this jacket to take with me on my hike through Washington on the PCT. Let me start by saying it is incredibly light weight. I had people ask me if it was really going to be waterproof or not. And initially I didn't actually believe it would be myself. But then (in true Washington fashion) . It rained. A lot. I threw on my jacket and wore it for three solid days. And let me tell you it is light. Very comfortable.
    My only wish for this jacket is for it to have armpit vents (or whatever the technical term is).

    Great Ultralight Jacket

    • Size Bought: Large

    This is the perfect jacket for travel or throwing in your day pack when there is a chance of rain. I found the minimal features to be just right. The hood is an ample size, and has a draw cord which is a nice feature. It stuffs very easily into the internal pocket. There is also a bottom cinch if you are in some real wind!

    Great ultralight jacket

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

    Incredibly light, stows in own pocket and clips to backpack, great for unexpected summer downpours. Comfortably cut. Definitely sweat when exercising but the small size/light weight convenience is an adequate trade off.

    Great lightweight jacket

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

    I bought the Helium Jacket after my North Face jacket lost all of it's waterproofing and even re-proofing it didn't work. I live and hike mostly in Colorado, so we don't have rain super often and it's usually not for long periods of time, so this jacket works well, as it's super light and doesn't take up tons of space in my pack. (It folds into it's own packet nicely.) It doesn't have much in terms of pockets or extra features, but since I don't wear it often or for long periods of time, it does the trick. Overall, I'd buy it again.

    Perfect Lightweight Rain Jacket!

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

    LOVE this jacket. I needed a lightweight and breathable rain jacket to bring on long wet weather trail runs and have handy on climbs when the weather turns and this fits the bill! It is so light - easily fits in my hydration pack or clips to my harness. Bonus points for the bright green color.

    The material feels really lightweight, hard to believe it's as waterproof as it is - but so far rain beads up nicely on it (unlike a couple other light rain jackets I tried). Fairly breathable - no pit zips, but can always leave the front open or leave the bungies loose.

    I don't really miss the pit zips or hip pockets on this - it's not what I bought it for. I have another rain jacket - a bomber goretex shell with pockets, pit zips, etc- so for colder weather, longer trips, etc I've got that one - but it's bulkier (can't clip to harness for windy belay stations and takes up most of the hydration pack or must be bungy'd to the back). I tried on the Helium HD in store and didn't feel those features were worth the extra $50.

    Size wise: 5'5", 130 lb, I'm a S by OR's size guide but purchased a medium because I've got more of climber build/muscular upper body and it drives me CRAZY when things are tight on my shoulders. I'm really happy with the fit of the medium and it's loose enough that can fit a lightweight down jacket or insulating layer under it in cooler months.

    No pitzips

    • Familiarity: I returned this product before using it
    • Fit: True to size

    I didn't end up keeping this jacket for two reasons:

    1) No pitzips!

    2) The material had a very plastic feeling to it.

    Finding a ultra light rainshell with vents is kinda tough.

    Or makes this jacket with vents and more pockets, adding 2 oz. its the Helium HD.

    A favorite of mine until I went to a goretex Active shell was the Marmot Super Mica. Similar ultra light thin fabric but with pit zips and reenforced shoulders for carrying a pack.

    Fabulous jacket!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    I am hiking the Camino de Santiago in Spain in September and needed a very light jacket that was waterproof. I looked at the reviews and it looks like it might do the job (along with my rain pants!). The jacket only weighs 5.5 oz which is helpful in keeping my backpack light for the journey! I'm 5 feet 4 inches and weigh 125 lbs. - the jacket is comfortable over a light under layer. If you want a big bulky jacket under then go a size up. :-)

    OK, here's a helpful followup. I returned from my trip and after hiking 3 days straight in the rain the jacket did leak a little. In the driving rain my head was not protected as much as I would have liked (the hood does not cover your head as other jackets do). Overall, however, it provided protection from the elements and definitely was light weight! :-)

    Best Lightweight Rain Jacket

    • Familiarity: I've put it through the wringer

    This is the perfect lightweight rain jacket to stash in your climbing, backpacking, or skiing pack, or just clip onto your harness. It's so lightweight, you don't even notice you're carrying it! It has the OR armpit zips right down to your waist so it's easy to get some added breathability without compromising access to your rack on your harness. The lightweight wire in the hood also helps give the hood some added form for keeping the rain out of the eyes. I love OR's stuffing system on most jackets, including this one, where you can stuff the jacket into the pocket and use the loop and clip (or your own biner) to clip it to your harness or on the outside of a pack.

    I'm 5'3" and about 135lbs and normally wear my OR jackets in a S, but go this one in a M to fit over my down jackets in case I need it for cold-weather protection. This setup works great and avoids me having to carry an extra jacket in the alpine.

    Essential Part of the Climbing Kit

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

    The Helium II is the jacket I take on every multi-pitch. It packs into its own small hem pocket, and has a clipping loop, so it sits on the back of my harness without me noticing it until I am happy to pull it on as rainclouds move in. I have scraped around in plenty of granite wearing this jacket and it has held up really well and is still very water resistant.

    I have also used this jacket as a wind layer while climbing and even while backcountry skiing. It cuts wind and breathes surprisingly well.

    The cut feels true to size.

    No frills, LIGHT.

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

    Very simple jacket--no hip pockets (-1 star) make it annoying to grab gloves/other things from underneath or your pants pockets, but for the ridiculously light weight of it, I can put up with small annoyances. I am 5'6, 140 lbs and normally wear small-medium. I got this in a M, and it fits very well--it's fitted, but it has enough space underneath for a light down sweater. Have yet to try it in pouring rain, but it's definitely an effective wind blocker.

    "Simply" the Best

      The Helium 2 jacket is simple and the best. The fit is great, it still repels water after much use, it'll make you feel light and fast, and you won't go anywhere without it. The jacket will get compliments time and time again. I'm normally a size Medium and the W's Helium in medium fits me well for spring/ summer layering. If you need more layers underneath you might consider buying it a size bigger.

      Why leave home without it?

        Stuff this jacket in the bottom of your pack and you'll never notice it's there. The one day you get your ropes stuck and the storm rolls in overhead you will remember it's there and be forever thankful. Check out the orchid with pink zippers -awesome colours!

        Love It

          I love this jacket. It's lightweight, breaths, keeps me dry and folds up into a small pocket. I like its simplicity and feminine style - not too teched out with features I'll never need. I live in Thailand where during rainy season, it's still hot. This jacket has been great at keeping me dry without making me sweat. I'm 5' 3" and 130 pounds. The M/M fits we well. There's room for layers and to move around, but it doesn't look too big.


            The new Helium 2 jacket is amazing. It's lightweight, compact, and well made. OR has done a great job with this jacket. It has been the perfect jacket for all of my spring climbing and skiing exploits. I always have it in the bottom of my pack for when the wind or the rain pick up. It's SO light and such a great layer. I can't say enough good things about this jacket!

            Weightless protection!

              Ladies, this jacket is WEIGHTLESS! Ok, it's 6oz. But 100% waterproof, very windresistant, and cute colors! It also breaths really well--probably because the material is so thin). This is the perfect ultralight jacket to put in your pack and forget about until the showers come.

              Just a note--when it comes to gear, I do like to go as light as possible as I am a smaller lady (5'4", 115lbs and the Small fits well) and this is definitely a keeper. Especially for the price, you're getting a high-performance shell that is more durable than you'd think...

              Lovin' This Jacket

                Rain jackets aren't heavy anymore! This jacket is simple, light, and fits great. The thing that keeps me coming back to OR Gear is how they keep it simple, and just make it right. I keep this in my climbing pack, and I always forget it's there until it starts raining, and then I'm psyched that I won't be soaked on the hike down.

                Would a men's small be comparable to a women's medium?

                Soon I will be traveling around southeast asia for about a year. It will be hot and humid. It's important for me to have a waterproof, windproof, and lightweight (preferably able to stuff into its own pouch) and breathable jacket. I'm considering this jacket or the Marmot Precip, the Mt. Hardware Plasmic or the Marmot Crystalline. Does anyone have comments to help my decision?

                Hey Lisa, this is Leta, rep for OR for why not buy the women's medim? Color? The men's small is not exactly cut like the women's medium, but could probably work. I own this jacket and absolutley love it - it is a perfect choice for what you are describing. Have fun!


                Does anyone know if there will be more sizes coming in anytime soonish?
