A vehicle written for the minutes that follow.

NIVIS is a modular alpine evacuation vehicle — built to reach a buried rider faster than a patrol sled, stabilize the patient in place, and ferry them off the mountain without a transfer. Where AERIS buys the first critical minutes, NIVIS spends them well.

01Context

The rescue starts after the fall.

The survival curve for a buried alpine fall has a second cliff — the window between being found and being reached by a team equipped to help. Patrol sleds are fast on packed runs. Off-piste, they aren't.

Window

The 6–15 minute gap.

After a burial, survival probability falls sharply after the first six minutes and again at fifteen. Helmets can extend the clock. Reach time is still the variable that matters most — and it depends entirely on the vehicle.

15min survival
threshold
Terrain

Steep, soft, and far from a road.

Most patrol-sled missions end at the edge of the groomed run. Beyond that, the vehicle has to float over deep snow, climb what a skier would hike, and do it without waking a secondary slide.

What if the rescue rode in with the rescuers?

Not a sled towed behind a skier. Not an ambulance waiting at the base. A vehicle that carries the patrol to the victim, and the victim off the mountain — in a single piece of equipment.

02Walkthrough

Three systems, one shell.

Drivetrain tuned for soft alpine, a treatment cabin that doubles as a rescue bay, and a deployable bed that meets the patient at ground level. Scroll through to see each of them in turn.

Surface close-ups of the elements that do double duty as aerodynamics, lighting, and visual identity — the seams where engineering meets sculpture.

Interior

The cabin is the bay.

Two patrol up front, modular crew + patient bay behind. The interior reads as a treatment room first and a vehicle second — every surface picks up a red accent on the way to the patient.

02Deploy

The stretcher comes down
to meet the snow.

Lifting a patient from the ground into a high-sill vehicle is the slowest, most painful moment of an alpine rescue. NIVIS eliminates it entirely: the treatment bay's floor detaches and rides a pair of rails down to the snow surface, so the patient is loaded at ground level and rises with the bed already locked.

Colorway

One body, five attitudes.

The shell is a single form — the finish is where the personality lives. From the signature alpine red to glacier white and midnight navy, each colorway is tuned for a different visibility profile and a different kind of day on the mountain.
