The Norrøna Lyngen Down850 ($489) is a midweight down layer that maximizes warmth and comfort. With 6.2 ounces of 850-fill down packed into a 13.5-ounce build, it’s designed for technical backcountry pursuits—think big ski touring missions and multi-pitch climbs—where a high warmth-to-weight ratio is key. Like most down jackets, it’s not built for wet conditions, and its thin shell fabric requires extra care. But if its price tag doesn’t scare you off, the Lyngen Down850 is a high-performance piece from a brand known for quality.

Norrøna Lyngen Down850
For this season's top puffies, see our guide to the Best Down Jackets.
With 6.2 ounces of 850-fill down in a men’s size large, the Norrøna Lyngen Down850 sits firmly in the “utility puffy” category—the kind of jacket I throw in my ski pack when I know I’ll need insulation but not a full winter-weight down jacket. On winter tours with temps ranging from the 20s down to the low single digits (°F), it provided all the warmth I needed when layered over a midlayer and occasionally a hardshell. For multi-day spring tours, I almost always bring two light-to-midweight insulated pieces rather than one bulkier jacket, which ensures I have a dry option when conditions turn sideways. The Lyngen Down850 has become a go-to in my kit for this purpose, too.
I also took the Norrøna Lyngen Down850 as my only insulation layer for a week-long winter climbing trip to Sedona, where we faced biting winds and temps dipping into the 30s. Whether trail running, multi-pitch climbing, or cragging, it was a welcome layer when the wind picked up or while standing in the shade of towering sandstone walls.
From a warmth-to-weight standpoint, the Lyngen Down850 is among the best on the market, with comparable warmth to the Patagonia Fitz Roy (6.4 oz. of 800-fill down) but in a 3.5-ounce lighter package. It packs in significantly more insulation than the Patagonia Down Sweater (5.3 oz. of 800-fill) and Arc’teryx Cerium (4 oz. of 850-fill), making it a warmer option without much of a weight penalty. If you need even more warmth, true belay parkas like the Rab Neutrino Pro (7.5 oz. of 800-fill) step things up—but at the cost of increased weight and bulk. And for serious winter camping or ice-climbing belays, down jackets like The North Face Pumori (11.3 oz. of 800-fill down) take insulation to another level.
All in all, the Lyngen Down850 hits the sweet spot for most active cold-weather pursuits, offering impressive warmth in a lightweight, packable package—as long as you’re not standing still for too long in deep winter conditions.
Norrøna lists the Lyngen Down850 at 13.5 ounces, which is impressive given that nearly half of its weight (6.2 oz.) comes from the down insulation alone. It’s over an ounce lighter than the Patagonia Down Sweater Hoody (14.8 oz.) while offering considerably more warmth. And despite its warmth, it packs down small—the Lyngen Down850 stuffs into its chest pocket, which includes a loop for clipping to a harness. When compressed, it’s slightly smaller than a 1-liter Nalgene bottle, making it an easy addition to a climbing kit or ski touring pack.
As a just-in-case emergency layer for winter use, the Lyngen Down850 is a no-brainer. Its packability served me well in my snowmobile kit, where I’d stash it in the tunnel bag and pull it out at the end of a ski tour. After a long day, it was a welcome refuge, providing instant warmth over sweaty base layers for the ride home. While the Lyngen Down850 can’t disappear in your pack like the 8.8-ounce Mountain Hardwear Ghost Whisperer, its warmth-to-weight ratio makes it a standout for those prioritizing both insulation and compressibility.
Wearing the Norrøna Lyngen Down850 feels like wrapping yourself in a warm, luxurious blanket. From the supple face fabric and liner to the fleece-lined collar and ultra-soft wrist seals, every detail is designed with comfort in mind. The trim fit helps seal in warmth and prevents draftiness, yet it never feels constricting. Best of all, while many down jackets develop a clammy feel when worn over just a thin base layer, the Lyngen Down850’s soft interior is comfortable enough to wear with just a T-shirt underneath.
Ample pocket space further adds to the Lyngen Down850’s comfort factor. The two generously sized, hipbelt-compatible hand pockets provide a cozy refuge for cold hands—so much so that I had to double-check that they weren’t fleece-lined. There’s also a spacious chest pocket, large enough to fit even the biggest smartphones, along with a snack or two. Overall, the Lyngen punches well above its weight in comfort, offering a premium feel that’s hard to beat.
The Lyngen Down850’s 10-denier nylon ripstop shell is exceptionally thin for a down jacket—comparable to the ultralight Mountain Hardwear Ghost Whisperer (10D) and slightly more robust than the ultra-ultralight Rab Mythic G (7D). Given its delicate fabric, I had initial concerns about durability, but after repeated snags in pack zippers and multiple days of crack climbing on desert sandstone, it has held up surprisingly well. After 20+ days of use across a variety of outdoor activities, it has proven so reliable that it’s now my go-to puffy for almost everything—even winter grocery runs. That said, if you’re wearing it as an outer layer while tree skiing, extra caution is advised.
This is the third Norrøna down jacket I’ve owned, and the Lyngen Down850 upholds the brand’s reputation for high-quality construction. Thoughtful details—like the snag-resistant nylon strip behind the zipper flap for smooth operation—and impeccable tailoring and stitching set it apart. At $489, it’s undeniably expensive for a midweight down jacket, but in return, you get premium construction and surprising resilience for such a lightweight design.
The Lyngen Down850 offers basic weather protection typical of a lightweight down jacket, with a DWR coating and a thin nylon shell. In cold, dry conditions, the DWR effectively sheds light moisture, such as spindrift and blowing snow. However, in warmer snow or sustained precipitation, the thin outer fabric quickly soaks through. In other words, this jacket works as a standalone layer in cold, dry snow, where flakes bounce off before melting, but it’s not suited for rain or heavy, wet snow.
Compared to the competition, some down jackets offer more robust shell fabrics that provide better moisture resistance—the Rab Neutrino Pro is one example—but these options come with added weight and bulk. Ultimately, the Lyngen Down850 prioritizes warmth and packability over weather resistance, making it best suited for dry, cold conditions with a hardshell as backup.

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 or 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.
Tester: 6’1” 175 lb.; 41” chest; 32” waist
Size tested: Men’s large
The Norrøna Lyngen Down850 has an athletic fit that helps seal in warmth while still providing plenty of room in the chest and shoulders for active movement. It runs true to size with a long cut, extending well below the waist to prevent ride-up and add extra warmth. The sleeves are similarly long, and even when fully zipped with the hood over a helmet, I maintained a full range of motion for everything from climbing to skiing.
While I’ve often worn the Lyngen Down850 as an outer layer, it also performs well as a midlayer—its thin fabric and streamlined fit prevent it from feeling too bulky under a shell. The one drawback as a midlayer is its long cut—some alpine climbing-oriented hardshells might fall short of covering the hem.
Patagonia Fitz Roy Down Hoody ($399): Less Efficient Warmth-to-Weight
The Patagonia Fitz Roy Down Hoody is a popular midweight down jacket with a solid warmth-to-weight ratio, packing 6.4 ounces of 800-fill down into a 1-pound 1.1-ounce build. However, it can’t match the thermal efficiency of the Norrona Lyngen down850, delivering similar warmth at a 3.5-ounce weight penalty. That said, the Fitz Roy has its advantages—it features a more durable 20-denier shell, a regular fit that wears better as a standalone piece, and comes in $70 cheaper. For those seeking a midweight down jacket without obsessing over every ounce, it’s a great alternative. You can read our review of the Patagonia Fitz Roy Down Hoody.
Rab Mythic G ($525): It Doesn’t Get Much Better
The Lyngen down850 offers incredible warmth for its weight, but it’s not the only ultralight midweight option (is that an oxymoron?!). Enter the Rab Mythic G. Weighing just 9.8 ounces—over 3.5 ounces lighter than the Lyngen—it still manages to pack in 4.5 ounces of 1,000-fill power down. While that’s 1.7 ounces less down than the Lyngen, the significantly higher fill power translates to more loft and better warmth per ounce. The Mythic G also features a reflective liner to further boost heat retention. It’s a no-frills, function-first design with a shiny lining, an ultra-thin 7-denier shell, and minimal adjustability, but for those looking to maximize warmth while keeping weight to an absolute minimum, it’s hard to beat. For more, read our Rab Mythic G review.
An ultralight midweight down jacket (is that an oxymoron!?), the Lyngen Down850 is a premium pairing for winter adventurers looking to maximize warmth while maintaining a minimal weight and packed size. Price and durability are its biggest shortcomings.

Named after one our our favorite mountains, the Fitz Roy is a soft and cozy mid-to-heavyweight jacket that offers efficient warmth for sub-freezing conditions. However, it lacks a few key features we look for in a belay jacket, including a long hem, two-way front zipper, and sufficiently wind and water-resistant face fabric.

Hold up, what!? We can’t believe Rab managed to pack this much warmth into such a lightweight jacket. You’ll pay a pretty penny for it, and it's unsurprisingly fragile. But the Mythic G is the only sub-10-ounce jacket we know of that can handle freezing temperatures.

For backcountry skiers, winter climbers, and cold-weather adventurers with a fast-and-light mentality, the Norrøna Lyngen Down850 nails the warmth, weight, and packability trifecta. That said, this is a midweight down jacket—too warm for summer conditions but not built for prolonged exposure to frigid temperatures or subzero cold. Instead, it excels as just-in-case insulation for winter pursuits—light enough to toss in your ski pack or clip to a harness without noticing, yet warm enough to be a welcome refuge on windy summits or mid-route belays. At $489, it’s a premium investment, but for weight-conscious winter adventurers, a down jacket like this is an essential piece of the kit.
