Our Take:
4.3/5
The Outdoor Research Helium Down Hoodie ($299) provides the performance you’d expect from a lightweight puffy, with one notable exception: Its waterproof construction on the hood, shoulders, and sleeves pushes this jacket into foul-weather use. While it’s no substitute for a waterproof shell and you do pay a moderate weight penalty for the thicker fabric, the Helium Down is a nice pick for cool outings with iffy forecasts.

Pros

Shell fabric is more durable than most, with 15D x 30D Pertex Quantum fabric and Diamond Fuse Technology.
Waterproof fabric at the hood, shoulders, and sleeves provides extra assurance in wet conditions.
Resists wind better than most down jackets.
Available in six sizes for men and nine sizes for women.

Cons

Heavy and bulky compared to down jackets of similar warmth and not nearly as soft.
Outdoor Research’s build quality (including cleanliness of stitching, durability of construction, etc.) is a step down from brands like Patagonia and Arc’teryx.

Packed with 2.9 ounces of 800-fill down (women’s version; men’s is listed at 3.9 oz.), the Outdoor Research Helium Down offers warmth that’s on par with standard lightweight down jackets like Cotopaxi’s Fuego or Outdoor Research’s own Transcendent. I found that the Helium provided adequate insulation—when paired with a fleece—for lounging in camps from the Cascades to the desert southwest in 40-degree temps. And it was a great summit jacket on Mount Baker with temps in the high 20s Fahrenheit (I wore it over my lightweight midlayer and shell). To me, this jacket finds a happy medium between too thin and too insulated. It’s a smart choice for most moderate temp, moderate-output outdoor activities such as summer backpacking in the Pacific Northwest. For cold-weather trips where the temperatures will be closer to freezing or wintertime use, though, I would opt for a warmer model.

At a listed weight of just under 1 pound (based on a women’s size medium), the Helium Down is roughly 3 to 6 ounces heavier than the average lightweight down puffy. This is the tradeoff of the jacket’s waterproof fabric and feature-rich build. For stuffing it down, the Helium packs into its left-hand pocket, compressing to slightly larger than a 1-liter Nalgene. Despite its weight and relative bulk, the Helium is packable enough that I took it on Baker as well as more casual summer backpacking adventures. While other down jackets offering similar warmth can be much lighter—the 850-fill, 15-denier Arc’teryx Cerium Hoody (see our Cerium review) is only 10.2 ounces—the Helium’s heavier weight reflects its standout durability and higher weather resistance.

The crinkly Pertex Shield fabric on the shoulders, hood, and upper arms means the Helium Down is not the softest puffy out there, but it’s still sufficiently cozy. The fleece-lined pockets are a welcome touch in cold weather, the collar is comfortable against my face when it’s fully zipped, and the hood is large enough to accommodate a helmet while still cinching down for a snug fit. Despite a lack of stretch, the Helium offers workable mobility, with a fair amount of space for light layering underneath. My only area of concern is the shoulders, which can feel constricting, especially over a bulky layer (this is a common complaint among down jackets, however).

The Helium is one of the most durable down jackets available in this weight class. Its Pertex Quantum face fabric is thicker than average at 15- by 30-denier, with the hood, shoulders, and upper sleeves featuring an even more robust 30D waterproof construction. Those materials translate to a puffy that’s rather heavy for its warmth, but the Helium is well-equipped for rough use. We’re also happy to report all the zippers operate smoothly without getting stuck. Sure, you can find higher overall build quality and stitching from brands like Patagonia with its Down Sweater Hoody ($329; read our Down Sweater review) or Arc’teryx with its Cerium Hoody ($400), but the Helium’s durable face fabric is top-notch. For its mid-range price of $299, the Helium offers good value for its quality and toughness. 

Weather protection is one of the Helium’s hallmark qualities and something that differentiates it from most of the down jacket market. The jacket’s hood, shoulders, and upper sleeves resemble a rain jacket, with a waterproof 2.5-layer Pertex Shield fabric. In testing, I found the waterproof sections easily brushed off dripping water from trees or blowing snow, and I felt confident wearing the jacket as my outer layer on top of Mount Baker. The lower portion of the Helium features Pertex Quantum—a common fabric found on down jackets—which is highly windproof and provides light protection against brief moisture. While a down jacket shouldn’t be relied upon as an outer layer in rainy conditions—down won’t insulate when wet—the extra protection on the Helium provides added assurance if the forecast calls for some precip.

Longevity

Choosing durable outdoor gear is perhaps the most effective way to reduce environmental impact—the longer it lasts, the less it needs to be produced. Our proprietary longevity rating evaluates overall build quality based on factors such as materials, fabric denier, component durability (including zippers and toggles), real-world performance as reported by our field testers, and our experiences with the brand.

Hood
The Helium’s hood is roomy enough to fit over a helmet or a hat, with an adjustment at the back to cinch it down. However, because the hood lacks side adjustments around the face, you might not be able to create as snug of a fit as with other puffies—it could feel a bit drafty. That said, the hood didn’t restrict my vision at all.

Storage
The Helium Down has five pockets: two large zippered hand pockets, one small external zippered chest pocket, and two internal drop pockets. The two hand pockets feature a brushed tricot lining and can each accommodate a phone and some snacks, and the left hand pocket includes a key clip. The chest pocket is small, but it can store a phone. All the zippers slide easily, even with thin gloves on. Plus, the two drop pockets are a great place to stash gloves.

I typically wear a women’s size 1X to 2X in jackets and chose the Helium in 1X. It fits true to size, though it’s on the slimmer side with a trim cut. There is some constriction across the shoulders that limits mobility, but otherwise, I maintained good freedom of movement. The Helium only reached my waist, making it slightly shorter than average (many down jackets provide at least partial coverage of my backside). It’s roomy enough to accommodate some layers underneath—though if you order your standard size, you’ll likely start feeling restricted in anything more than a base layer or lightweight fleece—while remaining trim enough to wear under a shell.

Arc’teryx Cerium Hoody ($400): Much Lighter Wet-Weather Resistance
If the Helium Down stands out for its weather resistance, check out the Arc’teyrx Cerium. The Cerium isn’t durable like the Helium Down (it has a 15D shell) and doesn’t have any special water-resistant fabric tech aside from a durable water-repellent finish, but it does feature synthetic insulation instead of down in moisture-prone areas like the collar and armpits. While we wouldn’t want to be caught in a squall with either, we trust the Helium Down’s waterproof fabric to keep more moisture at bay. On the other hand, the Cerium is about five ounces lighter, warmer, softer, and a much better midlayer option. For more, see our review of the Arc'teryx Cerium Hoody.


Norrøna Falketind Down750 Hood ($369): Durable but Less Water-Resistant
Another durability stand-out is the Norrøna Falketind Down750. This jacket features a 45-denier fabric at the shoulders, collar, and lower arms, which is even burlier than that of the OR Helium, and does a great job fending off the small abrasions and pinpricks down jackets often collect in high-use areas. It also patterns synthetic insulation in these areas for added breathability and durability. Like the Helium Down, these features combine to make the Falketind a more compelling standalone piece than a midlayer. If you’re looking for top quality, the Norrøna delivers, but the Helium Down still offers similar performance for $70 less.

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.

The Cerium offers extremely lightweight and packable warmth for technical pursuits like alpine climbing and backcountry skiing. Its streamlined fit is ideal for layering, too. However, given the price point, thin fabrics, and trim fit, we don’t recommend this jacket for everyday use.

The Falketind Down750 is a versatile down jacket that can play double duty for both lifestyle and backcountry use. Durable materials help extend the Falketind’s life and make it a great standalone piece. However, it’s a bit heavier and bulkier than many jackets of similar warmth.
