The Best Mammut Jacket for Every Activity | Complete 2024 guide

Last updated: January 23, 2025

We like the Mammut Dry Tour fabric found on the Mammut Stoney HS jacket and pant for its soft feel and stretch.

Mammut has a huge product line, and in this article I review their non-insulated shells to help you choose the best Mammut jacket to match your needs. I’ll start with a little background on the brand and then jump into the extensive product line.

With so many choices for jackets in the outdoor market, we at Outdoor Crunch tend to focus on brands that resonate with our Colorado mountain lifestyle. I appreciate technical gear made for outdoor adventures by people who share our passion for the backcountry. In the best cases you get a design-forward philosophy with a strong consideration for environmental protection. While Arc’teryx (one of our favorite brands for technical jackets and other gear) was founded in the Coast range of British Columbia, Mammut hails from the alpine playground of northern Switzerland. Both brands bring authentic mountain heritage to their product lines.

What I like about Mammut

Beyond their Swiss Alps heritage, there's a lot to like about Mammut. Their products are made thoughtfully for the activities we love. Details like reinforced peaks on hoods, shaped hoods that stay out of your face (unless it's a jacket for climbing or skiing, in which case the hoods are designed very specifically to fit helmets), double zippers for you folks on belay, athletic cuts for highly breathable active outerwear, and drawcords on ski jackets made to be used with gloves, make it clear that the designers in the Mammut office get after it. Their commitment to reducing their environmental impact is also important to us because the carbon footprint of outdoor gear is rather large. Talk the talk, walk the walk.

Subjectively, I also like Mammut’s style. Great fit, colorways, and an appropriate amount of steez.

More about the Mammut brand

Mammut has been around since 1862 and is a leader across Europe but is a newer entrant in North America. Founded as a family rope business serving agricultural needs, Mammut introduced its first glacier rope for alpine use in 1952. From then on their focus shifted to mountain products, introducing their first avalanche transceiver in 1969. Today, Mammut is headquartered in Seon, Switzerland, with a North American office in Denver and a warehouse in Vermont.

In their words, Mammut focuses on safety, protection, and resourceful performance. You can see a focus on mountaineering and climbing across their products, but they have clothing and gear for all outdoor pursuits. Mammut strongly considers the environmental impact of their business - from materials, to production, to logistics, and even packaging.

I’ll highlight material selection in this article, but if you want more detail on their environmental initiatives you can read their 100-plus page responsibility report here:

www.mammut.com/us/en/responsibility

Here are some key areas where Mammut works to reduce the impact of their products:

  • Materials
    • Recycled fabrics
    • PFC-free fabrics and coatings
    • Down insulation and wool are sourced in compliance with the Responsible Down and Responsible Wool standards (RDS and WDS)
  • Processes
    • Sustainable textile production sourced through the Bluesign system
    • Use of solution dying where possible to reduce the water used in dyeing fabrics
  • Packaging
    • They are working to reduce use of plastics through membership in the European Outdoor Group’s Single Use Plastics Project. To understand the importance of this issue, check out this article from Outside.
    • All cardboard packaging is made of 100% recycled content

Fabrics

Mammut uses fabrics they develop themselves as well as from well-known brands GORE-TEX and Pertex. Here are the key fabrics used across their shells:

  • Mammut DRY Active - Developed for trail running and fast tours
  • Mammut SOFtechTM - Multilayer abrasion-resistant, extra stretchy and breathable softshell fabric
  • Mammut DRY Tour - Developed for hiking, trekking and winter sports
  • GORE-TEX® Paclite - 2.5-layer laminate construction for a packable fabric that is waterproof and breathable
  • GORE-TEX ePE membrane - The GORE-TEX expanded polyethylene (ePE) membrane is their first PFC-free offering
  • GORE-TEX® Pro - 3-layer fabric with a membrane bonded to a rugged outer face textile equipped with DWR and a backer on the inside. GORE-TEX advertises this as being for climbing, ice climbing, mountaineering, freeriding and hunting. Completely windproof and made for abrasion resistance.
  • Pertex® Shield Air - Electrospun nanofibre web, with an open network of interconnected pores. Made to be ultralight and highly breathable.
  • Mammut DRY Expedition - Developed to tackle the challenges of high-alpine terrain
  • Mammut DRYtechnology™ Pro - Highly durable, windproof and waterproof (minimum 30 denier polyamide outer fabric, minimum water column rating of 20,000 mm).
  • GORE-TEX® Infinium - This fabric is windproof and highly breathable but offers protection only for light rain.

Water Impermeability (aka waterproofness)

This is measured in what is called the water column or hydrostatic head rating and measures how much pressure a fabric can withstand before water penetrates it. The test literally uses a column of water, with the result measured in millimeters of when the water penetrates the fabric.

This table from Evo gives a good overview of generally accepted guidelines.

Waterproof Rating (mm)

Water Resistance provided

Conditions

0-5,000m

No resistance to some resistance to moisture

Light rain, dry snow, no pressure

6,000-10,000mm

Rainproof and waterproof under light pressure

Light rain, average snow, light pressure

11,000-15,000mm

Rainproof and waterproof except under high pressure

Moderate rain, average snow, light pressure

16,000-20,000mm

Rainproof and waterproof under high pressure

Heavy rain, wet snow, some pressure. Think PNW.

20,000 mm+

Rainproof and waterproof under very high pressure

Heavy rain, wet snow, high pressure

Breathability

This gets a little complicated in that there are two measurements given here. All GORE-TEX fabrics use the Thermal Evaporative Resistance (RET) test. For RET values, a lower number is better. 

General guidelines for RET values:

  • >6g/m2 - Intense activity (running)
  • >12gm2 - Moderate activity (hiking)
  • >20gm2 - Breathable but you are going to be uncomfortable with any real activity

Mammut and Pertex fabrics express breathability in the amount of water vapor (in grams) that can pass through a square meter of fabric in a day (g/m2/24h). Using this method, a higher value means the jacket is more breathable.

  • <5,000g/m2/24h - Light activity
  • <15,000g/m2/24h - Moderate activity
  • >15,000g/m2/24h - Intense activity

Mammut jacket model details

I've spent a lot of time with Mammut's shells and have dug through the features, materials, and tech specs to pick my favorites across key categories.

Nordwand Pro HS

Mammut Nordwand Pro HS jacket

Womens Nordwand Pro in Sky

Mammut Nordwarnd Pro HS Men's hard shell jacket

Men's Nordwand Pro HS in Arumita-azurit

  • MSRP: $850
  • Fabric:  GORE-TEX Pro 
  • Weight: 622g / 568g
  • 2-way water repellant zippers, underarm 2-way zip ventilation, harness compatible pockets, zip-off snow skirt

The Nordwand Pro hard shell (HS) is part of Mammut's Eiger Extreme product line. This line represents their most technical products and spans gear from climbing equipment to expedition boots. This jacket has been refined over the years using feedback from Swiss mountain guides and Mammut pro athletes. The result is a jacket built for extreme alpine environments. The 80 denier GORE-TEX Pro fabric is made specifically for abrasion resistance and uses pre-consumer recycled nylon. Additional panels feature GORE-TEX Stretch for freedom of movement when swinging your ice axe. Areas prone to stress are reinforced to prevent damage. This piece is made for the abuse of the high mountains. Details such as microfleece chin protector are clearly the influence of athletes who have subjected this shell to harsh climates.

The openings to the pockets have been moved higher so as to be accessible when wearing a climbing harness. Nice.

  • MSRP: $899
  • Fabric:  GORE-TEX® Pro 
  • Weight: 684g / 633g
  • Long cut with relaxed fit, zip off snow skirt, Wrist gaiters, Backpack compatible chest and front pockets.

Another offering from the Eiger Extreme series, the Eiger Free Pro HS is designed for chasing backcountry pow lines. Everything about this jacket is made for snow. The drawstring adjustment on the hood and hem are made with COHAESIVE® stoppers designed for use with your gloves on. The long cut, snow skirt, and wrist gaiters give ample protection in the deep stuff. The recycled Nylon face fabric is 80 denier to provide durability against abrasion and the GORE-TE Pro membrane is highly breathable for a winter piece. The water repellant molded tooth zippers are a breeze to operate. This is an impressive ski and snowboard shell.

Alto Light HS

Men's Alto Light HS in Marine

  • MSRP: $219
  • Fabric:  Mammut DRY Tour 
  • Weight: 355g / 315g
  • 1-point adjustable hood, underarm ventilation, adjustable hem with drawcord

The Alto Light HS has a minimalistic design and delivers a waterproof, breathable, and packable jacket that is great for day hiking and camping. The 15,000mm waterproof rating is sufficient for moderate rain and even an occasional downpour, but it lacks the protection of an expedition-level piece. The Mammut DRY Tour fabric is very breathable, and the underarm zippers for ventilation is a nice touch at this weight and price point. The hood on this jacket is a great fit, coming from someone who has a strong dislike for helmet-compatible hoods when they aren't warranted. The single point adjustability ensures the hood doesn't drop into your field of view when dashing through a deluge. Stash this jacket in your daypack with plenty of room for your SLR and hiking bacon.

The Alto Light HS features a drawstring at the hem to adjust the length of the jacket.

  • MSRP: $249
  • Fabric:  Mammut DRY Active 
  • Weight: 170g / 155g
  • Low volume hood with reinforced peak, pre-shaped sleeves, elastic cuffs

Mammut's most breathable, packable, and lightest 3-layer hard shell, the Aenergy TR HS is made for high-output activities. Whether you are looking to break a PR on your favorite trail or training for your next marathon, this is a great piece no matter the weather. This jacket has an athletic cut, low-volume hood and pre-shaped sleeves to give it the proper fit for going fast. With a breathability rating of 20,000 g/m²/24h and a waterproof rating of 20,000mm, this is definitely a trail-worthy jacket made to keep you comfortable when things gets epic. You'll hardly notice it is stuffed in your ultra-pack, but you'll be happy it is when the sky turns dark.

The Anergy TR HS may be the lightest and most breathable in Mammut's line, but it still offers ample waterproof protection.

Ultimate VII SO Hooded

Men's Ultimate VII SO in Black

  • MSRP: $289
  • Fabric:  GORE-TEX® Infinium 
  • Weight: 530g / 441g
  • 4-way stretch material, 2-way front zipper, underarm ventilation, elasticated cuffs

I love the versatility of a good soft shell. They excel at general hiking and trekking, as well as every day use. They aren't insulated but offer a little more warmth than a non-insulated hard shell. I lean towards a soft shell as my 3-season daily workhorse. Whether hiking, camping, or fall days downtown I just prefer the fit and comfort they provide. The Ultimate VII SO features 3-layer GORE-TEX Infinium. This fabric has the GORE membrane as the outer surface of the fabric so that the hell doesn't take on any water during inclement weather. Polyester and Nylon on hard shells are fairly hydrophobic, but a soft shell can get weighted down when wet. Infinium is a relatively new innovation from GORE-TEX and this is a great application for it.

Mammut offers a non-hooded version for men. See is here:

Crater IV

Women's Crater IV in Savannah

Mammut Crater IV men's hard shell jacket

Men's Crater IV in Savannah-black

  • MSRP: $449
  • Fabric:  3-layer GORE-TEX fabric with PFC-free ePE membrane 
  • Weight: 482g / 444g
  • Helmet-compatible hood, MAMMUT High Reach Technology, pre-shaped sleeves, underarm ventilation

For those who enjoy the outdoors in all different ways, we think the Crater IV is an extremely versatile jacket. Whether it is a light day hike, summiting a 14er, or getting on belay, the construction and features of the Crater IV make it a great choice if you want one jacket for all of your activities. OK, it doesn't have a powder skirt, but for your hardcore 3-season needs this really hits the sweet spot. The helmet-compatible hood has both vertical and horizontal adjustment to get the fit just right. The pockets are also harness friendly, similar to Mammut's more mountaineering-focused models. It's also worth calling out that the face fabric and backing are 100% recycled polyester with a PFC-free GORE-TEX ePE membrane.
