Single trigger
Two lifelines. One pull.
One handle deploys the airbag and opens the breathing pathway simultaneously. No second decisions. No fumbling. Engineered for the worst three seconds of your life.

The avalanche pack that
keeps you breathing.
KissOfLife integrates an avalanche airbag with an active breathing system in a single backpack, the first product to target the 15–35 minute burial survival window.

2 systems -> 1 pullairbag and breathing, triggered together
70%less deaths caused by avalanches
The problem
Asphyxia kills.
Not the impact.
Every year, more than 100 people die in avalanches across Europe. Most of them don't die from the impact; they suffocate.
For a completely buried victim, exhaled CO₂ builds up in the snow pocket around the face. Within minutes, you lose consciousness.
Existing airbag packs are designed to keep you near the surface. But in a full burial, where no product currently helps, survival drops from 92% to 30% in just 20 minutes.

The solution
Everything you need.
In one trigger pull.
Airbag module
Stay near the surface
Rapid inflation reduces critical burial risk from ~47% to ~20%.
47→20%
Breathing interface
Breathe through the snow
Routes inhalation from fresh snowpack air. Vents CO₂ away from your face.
Cold-weather design
Works with gloves on
Every control surface, trigger, and mouthpiece is tested for use with ski gloves, goggles, and impaired coordination under stress.
The survival window
15 to 35 minutes
Survival drops from 92% to 30% in that window. KissOfLife is built entirely around extending that window, buying time until rescue arrives.
Technology
Three systems.
One chassis.
Each component solves a specific failure mode. Together they cover the full burial scenario from surface contact to rescue.
01
Airbag Module
Rapid-deploy inflatable system keeps the user near the avalanche surface. Reduces critical burial risk from ~47% to ~20% at deployment.
02
Breathing Interface
Mouthpiece-handle routes inhalation from fresh snowpack air via a filtered pathway. Exhaled CO₂ is vented away from the face to prevent rebreathing.
03
Backpack Chassis
Both systems are housed ergonomically in a single pack. The trigger position is optimised for one-handed operation with ski gloves in any orientation.
