Mammut Eiger Nordwand Advanced HS Review: For the Dialed Athlete
The Mammut Eiger Nordwand Advanced HS ($879) is a technical, streamlined Gore-Tex Pro hardshell built for serious alpine and ski mountaineering use. Our tester, an accomplished ski mountaineer, put it through a full season of big backcountry objectives in Washington State and came away impressed with its combination of protection, durability, and breathability at a competitive weight and packed size. The tradeoffs are real—a single exterior chest pocket and no pit zips make it a specialized tool rather than a true all-rounder—but for the right user, including our tester, it's a dialed and capable system.

Mammut Eiger Nordwand Advanced HS
For this season's top models, see our guide to the Best Hardshell Jackets.
The Mammut Eiger Nordwand Advanced HS follows the familiar formula of a premium alpine hardshell: Gore-Tex Pro ePE 3-layer construction, full seam taping, and a feature set dialed for serious mountain use. The face fabric is on the thinner end of the spectrum at 40-denier nylon, which was a slight concern given my tendency to wear out gear quickly, but performance hasn't suffered as a result.
I tested the Mammut Eiger Nordwand Advanced HS extensively in Washington's Cascade Mountains, from the wet forests and glaciated slopes of Mount Rainier to four days of bushwhacking and snowslogging in the North Cascades. Temperatures ranged from 10 to 50 degrees across these trips, with conditions spanning dry blowing snow, soaking rain, mist, and occasional sunshine. The Nordwand handled all of it. On the Ptarmigan Traverse, heavy fog and wet snow never translated to any moisture inside the jacket. Near Mount Rahm, 20 to 40 mph winds and bitter cold were no match for the shell when paired with a synthetic midlayer. The wide velcro cuffs seal more effectively than the thin straps found on lighter alternatives (Arc’teryx often uses these), and the extendable cuffs that fold out over gloves are a thoughtful touch for snowy conditions. For ski mountaineering in particular, this is a jacket that inspires confidence when the weather turns serious.
At 5'8" and 165 pounds, I've found comfort elusive in most hardshell jackets, which tend to run long in the arms and loose at the waist. The Nordwand walks a finer line than most. It's not a perfect fit, but in the mountains, a perfectly fitted shell is a contradiction in terms since you need room for varying layers. I wore this jacket for days at a time on long tours with heavy packs and multiple layers underneath, and had no complaints in any configuration. Whether I was moving hard in just a t-shirt and shell on a warm spring day, layered up with a midlayer, or adding a down jacket over the top during cold breaks, the jacket never rubbed or restricted movement.
The hood works well both with and without a helmet, bridging the happy medium that mountain use demands. A hood too large catches gusts and fills with wind-driven snow, while one too snug limits helmet compatibility. The Nordwand avoids both extremes. Cinches are there when needed but stay out of the way otherwise. More broadly, this is a jacket that doesn't try to be more than it is—no excess features, no unnecessary frills—and that restraint is part of what makes it so easy to live with.
The Nordwand's thin, non-crinkly construction breathes better than many of its Gore-Tex Pro peers. Whether I was climbing through Cascade rainforest, trudging through deep snow, or bootpacking up steep slopes, the jacket never became unreasonably hot to work in. On warm, misty valley approaches, it remained comfortable inside. For my specific uses of long ski tours and multi-day backcountry ski trips, this level of breathability was sufficient, and when the jacket felt like too much, taking it off was always an option.
The one notable omission is pit zips, which the Nordwand foregoes entirely in the name of simplicity and weight savings. For my ski mountaineering objectives, that was a non-issue. For users who run warm or operate in milder temperatures, though, the inability to dump heat quickly is a real limitation. The fabric earns high marks for passive breathability, but the lack of active venting does cost it points as a true all-rounder.
At 1 pound 0.2 ounces, the Mammut Eiger Nordwand Advanced HS is competitive for a jacket with this level of protection and coverage. It sits in a similar weight range as the Norrøna Trollveggen Gore-Tex Pro Light (15.2 oz.) and undercuts the burlier Arc'teryx Beta SV (1 lb. 1 oz.), both of which add pit zips and more storage. The streamlined Nordwand is more compressible than the Beta SV and comparable to the Trollveggen, packing down to roughly the size of two fists stuffed into its own hood.
For ski mountaineering in Washington's Cascades, where spring trips can swing 70 degrees in temperature across a single outing, a jacket that balances protection and packability is essential. The Nordwand fits that brief well. It's light enough to carry without thinking about it, durable enough to handle dense wet foliage and fallen timber on backcountry approaches, and protective enough to handle whatever the mountains throw at it.
The Nordwand's 40-denier nylon construction is backed by Gore's Pro rating, which signals top-end durability and protection. It's not as thick as some alternatives—Arc'teryx's Alpha SV and Beta SV both use 100-denier face fabric—but Mammut's more balanced approach pays dividends in breathability and packed size without obviously compromising toughness. After 15 days of hard use, including extensive bushwhacking with overnight packs and ski mountaineering in demanding conditions, the jacket shows no signs of tearing, loose threads, or delamination. For context, a pair of ski pants from another brand used over the same period accumulated several tears and obvious wear points. The Nordwand has held up considerably better.
The two-way main zipper has performed well throughout and shows no signs of wear, though it can be slightly sticky at times. That's a minor gripe on an otherwise well-executed build. The jacket's simplicity is also a durability asset in its own right, as fewer features means fewer points of failure.

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.
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.
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.
PFAS-Free Waterproof Membrane
The membranes used in waterproof products such as rain jackets, ski jackets, and shoes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are valued for their 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’s waterproof membrane is PFAS-free, while a red X means it contains PFAS.
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.
The Mammut Eiger Nordwand Advanced HS's pocket situation is minimal by any standard. There is a single exterior pocket, which was the one aspect of the jacket I found myself wishing were different. In practice, the only time it became a real inconvenience was at camp, when I needed somewhere to stash gloves. Two internal pockets inside the jacket help offset that limitation, though they require a habit adjustment to use consistently. For a jacket built around weight savings and simplicity, the tradeoff is understandable, if not always ideal.
Beyond storage, the feature set is clean and purposeful. The hood cinch, waist cinch, reinforced helmet-compatible bill, and wide velcro wrist straps all work together without feeling clunky or excessive. The extendable cuffs that fold out over gloves are a standout detail for snowy conditions. And finally, the harness-friendly, two-way main zipper pairs well with the alpine climbing intent of the shell.
Tester: 5'8", 165 lb.; 31" waist
Size tested: Men's medium
For me, my usual men’s size medium fits well, with enough room for a down jacket underneath on colder days without constricting movement. The jacket zips fully to the chin even with a midlayer underneath, which isn't always a given with hardshells in this category. Sleeve length and waist placement work well for my proportions, and after days of continuous wear the jacket hasn't rubbed or caused any discomfort. For a jacket meant to transition from below-freezing mornings to near-boiling midday exertion in Washington's mountains, the range of motion and layering versatility it provides are spot-on.
Norrøna Trollveggen GTX Pro Light ($749): Comparable Build, More Features
The Trollveggen and the Nordwand share a similar philosophy: Gore-Tex Pro ePE construction with a relatively thin 40-denier face fabric that keeps weight down without sacrificing protection. In practice, both performed well in serious alpine conditions, and neither feels overbuilt for ski mountaineering and technical mountain use. The Trollveggen adds pit zips and a second chest pocket, giving it superior versatility. But if you prefer a cleaner, more stripped-down tool, the Nordwand makes a compelling case. To learn more, check out our Norrøna Trollveggen GTX Pro Light review.
Arc'teryx Beta SV ($800): Burlier and Pricier
The Beta SV is the more heavy-duty option of the two, with 100-denier nylon throughout the entire jacket compared to the Nordwand's 40-denier construction. That added fabric weight translates to superior durability and a more bombproof feel, but also more heft at 1 pound 1 ounce and a stiffer, crinklier hand. The Beta SV also adds pit zips and an external chest pocket. For ski mountaineering and long tours where minimal weight and packability are priorities, the Nordwand has the advantage. For climbers and mountaineers who want maximum durability and a fuller feature set and have the budget for it, the Beta SV is worth the premium. For more, read our review of the Arc'teryx Beta SV.
A technical standout, the Eiger Nordwand HS delivers bombproof protection in a surprisingly compressible package. It excelled for us as a multi-day ski mountaineering shell, but minimal storage and a lack of pit zips limit versatility.

Is the Eiger Nordwand for You?
Hardshell jackets are already a specialized piece of kit, and the Mammut Eiger Nordwand Advanced HS narrows that target audience even further. Minimal exterior storage and no pit zips really do impact its do-it-all potential—there’s a reason top sellers like the Arc’teryx Alpha SV have those features. But as our testing proved, the streamlined setup delivers a lot while taking up minimal space in your pack.
