Backcountry skiing already asks a person to trust two sticks, a weather report, and the suspiciously confident friend who says the line is probably fine. So if there is going to be a backpack involved, it might as well be the one that brings its own electronic emergency balloon to the snow party.
The Mammut Haldigrat 30 E2 Airbag M/L is a 30-liter ski touring backpack with an integrated electronic avalanche airbag system. Instead of relying on a compressed-gas cartridge, this pack uses the Alpride E2 system, which is powered by supercapacitor technology and built to deploy quickly at high pressure, even in freezing conditions.
That is the whole strange appeal here: it looks like a serious black mountain pack with orange safety details, but hidden inside is a small piece of Swiss overengineering that exists because snow can occasionally decide to become a moving wall. It is not a magic shield, and it does not make risky terrain safe, but it does turn the backpack into something more dramatic than a pouch for granola bars and emergency socks.
Mammut positions the Haldigrat E2 for big ascents and serious descents, which is a polite outdoor-industry way of saying this bag is for people who think a relaxing morning starts with checking avalanche forecasts before breakfast. The 30L capacity gives it enough room for layers, water, food, and safety equipment, while the integrated airbag system keeps the pack in the avalanche-rescue category rather than the ordinary backpack aisle.
An Airbag Backpack Without the Cartridge Drama
The most interesting part is the Alpride E2 system. Alpride describes the E2 as a more compact and lighter successor to its E1 system, with a new LCD display, a new deflation button, and an electronic pressure relief valve. The system uses supercapacitors, which store electrical energy without the same cold-temperature sensitivity associated with typical lithium batteries.
In practical terms, that means the pack can support repeated practice deployments without the old ritual of replacing or refilling cartridges. That is helpful because an avalanche airbag is not the sort of thing anyone wants to learn for the first time while gravity is holding a meeting. Practicing the pull, repacking the system, and understanding the controls all become less precious when each test does not feel like launching a tiny expensive rocket.
Alpride says the E2 can be charged by USB-C or by two AA batteries, and that the supercapacitor approach is not subject to the same transport restrictions as cartridge systems. Mammut also describes the system as airplane-safe. For people who travel to ski, that matters, because airport security is already a theater production without adding a pressurized cylinder to the cast.
The Haldigrat 30 E2 is also built as an actual ski pack, not just a safety appliance with shoulder straps. Mammut lists a back opening, a 3-way zipper book-style opening, a front pocket for avalanche safety equipment, ski and snowboard carry options, attachments for ice axes or poles, a helmet holder, lateral compression straps, and hydration compatibility.
- Integrated Alpride E2 electronic airbag system using supercapacitor technology.
- Back-panel access and a 3-way clamshell-style zipper for reaching packed gear.
- External avalanche safety pocket for shovel, probe, and other rescue essentials.
- Removable diagonal ski carrier plus snowboard and splitboard mounting options.
- Height-adjustable trigger handle that can be positioned for left- or right-side use.
- U-frame suspension, helmet holder, pole or ice-axe attachments, and hydration compatibility.
This is the kind of pack that quietly admits backcountry people are chaotic inventory managers. You need climbing skins, goggles, food, a spare layer, water, gloves, a beacon, a shovel, a probe, maybe a helmet, maybe poles, maybe enough tiny things to recreate a ski shop inside a snowbank. The Haldigrat does not make that personality trait disappear, but it does give the mess a purpose-built structure.
The Specs That Keep It From Being Just a Mountain Backpack With Big Feelings
Mammut’s current US listing identifies this model as a one-size M/L pack with a CONTACT U Frame suspension system, a 30-liter volume, a 48.5 cm back length size system, and a listed width of 30 cm and height of 56 cm. The pack itself is listed at 1510 g, while the backpack with the airbag comes in at 2650 g.

| Back length | M/L, listed at 48.5 cm |
| Dimensions listed | 56 cm high, 30 cm wide, 20 cm long |
| Pack weight | 1510 g for backpack, 2650 g with backpack and airbag |

The pack also includes orange detailing, which Mammut says helps you find your avalanche equipment. That may sound like a tiny thing until you imagine digging through a black backpack in blowing snow while your hands have become two frozen office staplers. High-contrast design choices are not glamorous, but they are exactly the sort of mountain gear detail that earns its keep.
There is also something refreshing about a gadget whose purpose is extremely clear. This is not a smart toaster trying to develop a social network. It is a backpack for avalanche terrain that can inflate an airbag from an electronic system, then go back to carrying ski gear like a responsible adult. The comedy is not that it is silly; the comedy is that it is very serious and still looks like it might dramatically puff up if the mountain gets rude.
Of course, an avalanche airbag is not a replacement for education, forecasting, group decision-making, a transceiver, shovel, probe, or the ancient survival technique known as turning around. Mammut classifies the item as personal protective equipment and tells users to read and follow the manual. Alpride’s own manual language for E2 systems also stresses that avalanche airbags cannot prevent avalanches and should not encourage bigger risks.
Why The E2 System Is The Interesting Bit
The Alpride E2 system is the reason this pack is more than a regular avalanche backpack refresh. Alpride lists a 162-liter airbag volume, a full system weight of 1140 g, USB-C charging, optional AA-battery charging support, an LCD display for checking capacitor and battery status, visible LED indicators, and a radial compressor designed to deliver fast airflow and high inflation pressure.
The supercapacitor angle is especially useful for cold weather because Alpride says the technology is not sensitive to lower temperatures in the same way as lithium-ion or lithium-poly batteries, with performance listed from -30 degrees C to +50 degrees C. That is exactly the sort of absurd temperature range that makes sense when the product is built for people who voluntarily hike uphill in winter.
The system also has an automatic pressure relief valve that activates after inflation, according to Alpride, and a deflation button accessible from outside the backpack. That does not make repacking an airbag sound like a spa appointment, but it does make the system more approachable than the cartridge era, where every practice pull could feel like a financial decision.
Mammut’s own pack design wraps that electronics package inside a touring-focused shell. The back opening helps you reach gear without unloading the entire pack like a yard sale. The avalanche safety pocket keeps critical rescue tools separated. The ski, snowboard, and splitboard carry options make it adaptable for different winter missions. The left-or-right trigger placement is another genuinely practical detail, because emergency handles should not be designed as if every skier has the same body, habits, and dominant hand.
This is also why the Haldigrat E2 has a better hook than many expensive outdoor packs. It is not merely lighter, newer, or dressed in this season’s shade of mountain goth. It changes the airbag mechanism people interact with, while keeping the rest of the pack grounded in normal ski-touring needs. It is a backpack with a job, a backup job, and a tiny control system that would like you to charge it before doing anything dramatic.
