Product Reviews

Rated 5 out of 5 by from So far a great buy! [This review was collected as part of a promotion.] Have not had it out on the trail yet but did test in a total Florida downpour for about 10 minutes. Held up very nicely. Planning to use as a shell and rain gear on Kilimanjaro

Rated 3 out of 5 by from Waist level cinch tore from jacket upon first use [This review was collected as part of a promotion.] Material is really lightweight and seems to be good and breathable. I wish pockets were bigger. I give 3 stars because it's a delicate jacket. If you don't be extra careful with it, you could have my experience. I pulled cinch at waist level and it tore from the jacket. I had to return that. Now that the return process is over, I think I'll get the same jacket again and just treat all the cinches super delicate. I'm pretty sure this is a great jacket, that's why I'm going to get it again, but just be careful with the cinches as mine tore from jacket on first try. Before this I had the Interstellar jacket and the Ferrosi hoodie and both of those have been great.

Rated 5 out of 5 by from Wow, who stole the weight from my jacket? I have owned a steady stream of wind and rain shells, starting with a scale-busting 60-40 cloth parka back in he 1970's, back when only heavy plastic and oil cloth were waterproof, and breathable and waterproof could not apply to the same jacket. I currently have a heavy, classic, Goretex 3 layer shell, two ultralight OR pertex windshells (love them), a softshell, and a couple of well-worn breathable/waterproof shells by other well-known manufacturers. This new shell awaits field use, but it is certainly the lightest weight shell I have ever owned. This is so light that it will always be in my day-hike bag, my backpack, and in my travel bag, even when skies are blue the air is calm, and no rain is expected. Breathable, Waterproof AND good-looking! This is one of the few lightweight items in my closet that has a two-way main zipper, thank you Outdoor Research, that gives me greater flexibility in how I wear the jacket. I find that most of the catalog models who wear shells in outdoor gear catalogs are slender - six-foot tall guys who wear a size Medium, and many reviews are by equally slender folks. Maybe I am the only chunky outdoorsman around, but at six-feet and 235 pounds, I wear an XXL. This XXL fits well (not overly baggy) over a couple of shirts or a down vest, and I could easily wear it over over my Helium down jacket without feeling constricted. I have a somewhat long torso, but this jacket is still long enough to cover most of my buns, so that when I vigorously hike, I don't have to worry about rain getting between the bottom of my jacket and the top of my rain pants. Like all ultralight clothing, I suspect that this will scuff or even tear if you regularly drag yourself over boulders or through thorny thickets, but my experience is that pertex diamond fuse fabrics hold up well to moderate use. I cannot imagine that shells this well made will get much lighter, and certainly, they won't beat the price I paid for this on sale.

Rated 5 out of 5 by from Awesome versatility I got this jacket last fall and have used it in a variety of scenarios, each time being very pleased with how it performed. I first used this jacket to climb a winter 14er, and the jacket was incredible. It did an amazing job blocking out just about all of the wind, but almost more importantly it kept me warm. I've worn this jacket about a dozen times skiing now and it's been awesome. The waterproofing on the jacket is great. I've skied in some wintery mixes/rain with this jacket and have never once gotten wet. My GORTEX gloves got wet before my torso ever did. One of my favorite features about the jacket is the material, and how lightweight it is. On some of the hotter spring ski days, I was able to stuff my entire jacket into the pocket of my bibs. The same applied to the hikes I've been on - super easy to store in a backpack without taking up much room. The length of the jacket feels a little long compared to others, which threw me off at first, but now I like it. The length of the sleeves could be considered a little long, but I like that because I can easily velcro them around my gloves. I'm 6'1 with an athletic build and a medium fit great. I think my only complaint about this jacket is the lack of armpit zippers. If those were added I think this would be a 10/10

Rated 5 out of 5 by from Light, breathable, and dry. An absolute steal if you grab it during the end of season sale. We've been blessed with a wet winter in CA, so I've had ample opportunity to test this jacket and it's performed admirably. With Outdoor Research, I don't feel like I'm paying for the brand rather than the quality. I'm 5'10" and 150 lbs. and the small perfectly fits a trim fleece and down jacket with enough room to move. I'm the only one at the office with a dry torso.

Rated 4 out of 5 by from Weird sizing This jacket is light and has a bunch of pockets which are nice. I like the hood fit with and without a helmet. Like other reviewers, I have also experienced fraying of the face fabric around the cuffs and other areas after not too much use. My biggest gripe though is the fit of the arms. I'm 5'10", 165lbs, broad shoulders, athletic build, and have long arms. I ordered a Large originally. It was comically large. I swapped for a medium, and it is somewhat trim fitting. I can't layer much underneath (sweatshirt thickness max.) because there is not enough room around the elbows, and I can't bend my arms to reach my collarbone. My arms are not particularly large in diameter. The medium also does not reach my wrists with my arms raised straight at shoulder level. Kind of a bummer with gloves.

Rated 5 out of 5 by from Perfect for ski touring I finally got to take this jacket ski touring and I love it. It checks all of the boxes. I'm 5'8" 150. I have tons of OR jackets. I'm usually a medium but with my hard shells, that doesn't leave room for layering / throwing it on over a puffy on cold days. This jacket fits bigger than most so I can easily put it on over my ski puffy or a hoody mid-layer, but it doesn't feel too baggy. Other things that are great: - It's super light and packs small. This was key for me since the hardshell is often in the pack. - The hood is big enough to go over my helmet - It has glove stash pockets - It has the foam inserts so it stays put under a harness (haven't verified how well it works yet) - Zips up from the bottom too for belaying Only 1 day in it but so far, it's exactly what I've been looking for for touring and ski mountaineering. I also think it will be good for winter alpine climbing.

Rated 2 out of 5 by from Nice fabric with unknown performance and odd pockets I generally like OR and Ascentshell from previous jackets and have been looking for something like the Helium Ascentshell for ages. It ticks many boxes in being light, functional and versatile but also leaves you frustrated in that it could be so much better with a few minor changes. Really makes me wonder if they have real users test or design these jackets. Fit of this jacket is good. I'm 6" 180lbs 40" chest average build and arm length and Medium fits well. Has room for layers (fleece + light down/puffy) underneath but can be worn without as well. It has a long hem which is good for staying under pack hipbelt/climbing harness with foam pieces in the hem. I got yellow color which is nice to be visible on the mountain with bright color and it looks good. Unfortunately, this color/material attracts dirt easily and isn't easy to clean. I've only worn it for 1 month on 8000m mountaineering trip where the majority of the time is on glacier/snow and the cuffs are dirty looking and can't get them clean. Also the cuffs have started to fray so not confident about how long the jacket will last. Material isn't crinkly/noisy and soft/light so moves well. I feel like this Pertex Ascentshell doesn't breathe as well as standard Ascentshell and might not be as durable, but this is just based on feeling and not any standardized testing. It's too bad that OR didn't share a comparison of the performance between Pertex Ascentshell vs Ascentshell to see which is more breathable and waterproof based on their testing. The pockets are a disappointment. They advertise: High Hand Pockets Placed Above Hip Belt and Harness & Dual Internal Mesh Stash Pockets. But the hand pockets are directly underneath hip belts and harness. Napolean style large chest pockets would be much more functional and wouldn't interfere with harness. The external chest pocket is very small and barely fits a small phone. The mesh stash pockets are too narrow for skins.
