Updated:
Sep 08, 2026Weather resistance isn’t usually a down jacket highlight, but the Outdoor Research Helium Down Hoodie ($350) flips the script. This updated, lighter version of the well-loved medium-weight puffy features 2.75-layer Toray Dermizax waterproof material on the shoulders, upper arms, and hood, giving it an edge during surprise precipitation. Tack on packable three-season warmth, a whole lot of comfort, and plenty of pockets, and you get a jacket that stands out from the competition.

Outdoor Research Helium Down Hoodie
For this season's top puffies, see our guide to the Best Down Jackets.
The Outdoor Research Helium Down Hoodie is best known for its weather resistance, but it still packs enough warmth for three-season backpacking and chilly (if not truly cold, per se) conditions. OR doesn’t provide the fill weight for the jacket’s 800-fill down, but after about three months of wearing it, I’ve concluded that the Helium is a bit warmer than the Mountain Hardwear Ghost Whisperer (3.3 oz. of 800-fill) but not quite as warm as the Down Sweater (5.3 oz. of 800-fill down). It’s cozy enough for three-season backpacking trips or chilly shoulder-season days at the crag, while not dipping into ultralight or midweight territory on either end.
During testing, I took the Helium Down Hoodie on a two-week trip to Lake District National Park in England and a three-day hut trip in Picos de Europa National Park in northern Spain. Temperatures swung from the 40s to the low 50s—conditions that were right in this jacket’s wheelhouse. At the upper end of the range, I paired the Helium with a long-sleeve base layer and felt comfy; on cooler evenings up high in the Picos, I added a fleece for a winning combo. The Helium is too warm to wear while hiking in those conditions, but it proved perfect for relaxing near refugios in the evenings or quickly throwing on during windy snack breaks.
All told, the Helium’s warmth level makes it really versatile for three-season wear. It’s not warm enough to wear as a go-to puffy in deep winter, and it might be a bit overkill for summer adventures, especially if you don’t venture too high. But it’s about as versatile as it gets for the range of conditions in between, and has been an ideal do-it-all midlayer for my early summer pan-European adventures.
Designers cut some grams from the previous version of the Helium, taking it from 1 pound 0.2 ounces to 15.4 ounces. The jacket packs down into one of its zippered pockets to the size of a thick paperback—think “Harry Potter and the Goblet of Fire.” That’s not very small compared to sub-10-ounce, ultralight puffies like the Ghost Whisperer and the Mythic G, but it is still compact enough to fit easily in a pack.
From a warmth-to-weight perspective, the 15.4-ounce Helium is about on the same level as the REI Co-op Magma 850 and the Black Diamond Access Down 2.0. It’s not crazy light like the Mountain Hardwear Ghost Whisperer (8.8 oz.) and the Rab Mythic G (9.8 oz.), and not even as efficient as the Patagonia Down Sweater (which packs 5.3 oz. of 800-fill into a 14.8-oz. build). It’s great for missions on which I’m not too concerned about how many ounces I’m carrying, including day hikes, hut hiking, and casual backpacking. Plus, I think the Helium’s superior weather resistance (which adds weight) compared to the other models I just mentioned is well worth the good-but-not-great packability.
Just as you’d hope for with a down puffy that’s this versatile, the Helium is highly comfortable. I feel quite cozy whenever I put it on; the fabric both inside and outside (both nylon, with a slightly lighter material inside) feels good against my skin, so I can easily wear it over a T-shirt. While the materials aren’t stretchy, the cut lets me move freely and use my full range of motion, which is always appreciated whether I’m puttering around camp or strolling to dinner in town.
The Helium's collar and hood feel good even when the jacket is fully zipped up. I often find that a down jacket’s comfort is directly related to its weight, and so the Helium, which is far from insubstantial, offers an appealing amount of heft without tipping into too-heavy territory. I wore this jacket basically every day in the Lake District, which was as cold and chilly as its reputation alludes to, and the Helium kept me cozy and comfortable in every scenario.
In its most up-to-date build, the Outdoor Research Helium Down Hoodie features a 20-denier nylon face fabric on the majority of the jacket, while the waterproof overlays on the hood, shoulders, and upper arms are 15-denier nylon. Overall, it will be slightly less durable over time than the prior-generation model, which had a 15-denier-by-30-denier nylon shell, 30-denier waterproof material, and was one of the tougher puffies at this weight on the market.
That doesn’t mean the updated Helium can’t hang, though. I’ve worn this jacket for about three weeks’ worth of actual testing days, and it still looks brand new. Its materials might not be as burly as something like the (heavier) Patagonia Durable Down Parka or the Rab Microlight Alpine, but the construction quality seems high, and its fabrics are mostly in line with competitors like the Down Sweater and the Black Diamond Access 2.0, which have 20-denier nylon shells. You might have to pay a tad more attention to the thinner waterproof sections, but everything I’ve seen so far from the Helium points to it being a major part of my kit for a long time.
The protection on this jacket is far better than on any other puffy I’ve ever worn, hands down. As with its previous iteration, the Helium features waterproof material on its hood, shoulders, and upper arms. This time around, Outdoor Research built it with 2.75-layer Toray Dermizax in those areas, a change from the 2.5-layer Pertex Shield of the previous model. Although the waterproofing is only on the jacket’s upper portion, that’s the area of the puffy most exposed to the elements. You’ll certainly notice the added protection in a light rain or in drippy conditions when you have to be more careful with a standard down jacket.
Many of the days I spent in the Lake District were rainy, but I often didn't feel the need to put on a rain jacket because of the Helium’s added protection. At one point, I decided to walk to dinner about 15 minutes away without a shell to really put this puffy through its paces. It was raining hard—truly coming down—but the top half wicked water away and the down stayed dry. I was pleasantly surprised, as I’ve simply never had a puffy that I’d trust in wet conditions. Of course, keep in mind that the rest of the Helium is not waterproof, so I would of course throw on a rain jacket if the forecast calls for sustained precipitation. But for quick bouts of rain or flurries, this is all the coverage I need, and it's a great reason to keep reaching for this jacket as my daily driver.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
Responsible Down
The Responsible Down Standard (RDS), developed by Textile Exchange, is the leading certification for responsibly sourced down and uses third-party audits throughout the supply chain to verify animal welfare, responsible farming practices, and safe working conditions. Recycled down is another responsible choice that helps reduce demand for newly sourced down while keeping existing materials in circulation. A green check mark indicates a product uses responsibly sourced or recycled down, a yellow check mark indicates the brand sources responsible or recycled down for the majority of its products but does not specify it at the product level, and a red X indicates the product does not use responsibly sourced or recycled down.
PFAS-Free DWR
Durable water-repellent (DWR) finishes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are used in outdoor gear for their strong resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product uses a PFAS-free DWR, while a red X means the DWR contains PFAS.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Repair Services
Repair services extend the lifespan of outdoor gear and reduce overall consumption, though programs vary widely. Some brands offer comprehensive repairs for a range of issues, while others provide limited or no repair support. A green check mark indicates a robust repair program, a yellow check mark indicates limited repair services, and a red X indicates the brand does not offer repair services.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one of the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
Hood
I’m a fan of the Helium’s hood design. The single cinch on the back is easy to use, and the hood fit my head well while I was wearing a hat and kept out the wind. Outdoor Research mentions offhand that the hood can fit over a helmet, but a fair warning that that might be a tight squeeze. And of course, the waterproof material on the outside of the hood is fantastic for keeping your head dry.
Storage
The Helium’s pocket layout is fairly standard, which is to say welcome and helpful. It has one zippered chest pocket, two zippered hand pockets, and an internal mesh drop pocket. The hand pockets have a fleece lining that’s great for keeping my hands warm and cozy. Storage isn’t anything fancy, but it works during the activities the Helium is designed for.
Tester: 6’2”, 175 lb.; 41” chest, 31” waist
Size tested: Large
I went with my typical size, large, and the Outdoor Research Helium Down Hoodie fit mostly how I want an everyday puffy to fit. The arm length hits right past the wrist, and the body length feels spot on. I preferred the cut to that of another Black Diamond puffy I was testing, which was a bit too long in the torso; I think the Helium's silhouette is a bit nicer for regular use. Plus, it’s great for layering: I can easily throw two layers underneath and a shell on top for maximum warmth.
Patagonia Durable Down Hoody ($365): Durability Focused
The Helium Down used to stand alone in the light-to-midweight jacket space, until the Patagonia Durable Down came along. Released for fall 2026, it's headlined by a 50-denier Ultra-PE ripstop face fabric and Pertex Quantum Pro lining, a one-two punch for durability and weather resistance. The Ultra-PE is in a different league when it comes to abrasion resistance, making this a jacket genuinely meant to take a beating at the crag, doing outdoor work, or as an everyday piece. Ultra-PE is also waterproof, though without taped seams, the jacket falls short of true waterproof construction. The key tradeoff is weight: at 1 pound 7 ounces versus the Helium's 15.4 ounces, the Durable Down is out of the running for most backpacking or ski touring applications. But for casual use and cragging, it's second to none. For more, read our review of the Patagonia Durable Down Hoody.
Rab Neutrino Pro ($450): The Warmer Sibling
Think of the Neutrino Pro as the Helium Down's older sibling—the one you call in when temperatures drop below about 40 degrees. It doesn't feature true waterproof fabric, but its Pertex Quantum Pro shell is one of the most wind- and water-resistant fabrics available, more than capable of handling flying snow and the odd icicle drip. The key difference is warmth: With 7.5 ounces of 800-fill down, the Neutrino Pro keeps you insulated as temps fall into the teens and single digits. At 1 pound 3.9 ounces, it's over 4 ounces heavier, but it's what you want for winter climbing, après tailgate hangs, or anything that involves standing still in genuinely frigid temperatures. To learn more, read our Rab Neutrino Pro review.
An offshoot of OR's weather-protective shell collection, the Helium is an extra-durable, extra-water-resistant down jacket that can be confidently tossed around and worn as an outer layer. However, due to the added tech, it’s heavier and bulkier than most jackets of similar warmth.

Craving a puffy that has more weather resistance than your typical down jacket, but higher loft than a synthetic? The Outdoor Research Helium Down Hoodie might be the answer. This is a layer for folks who don’t want to automatically reach for a rain shell when it starts to drizzle in camp on a backpacking trip, or who want an around-town puffy that can survive a quick shower. With its versatility as a three-season midlayer and its comfy build, the Helium should be on anyone’s list alongside category stalwarts like the Down Sweater.
