ALTI EQUIPMENT HYPERBARIC CHAMBER. TESTED ON CLIMBERS
…
SINCE 2023, FEEDING THE RAT EXPEDITIONS HAS BEEN COLLABORATING WITH ALTI EQUIPMENT, RESULTING IN THE FIRST ULTRALIGHT PRESSURIZABLE CHAMBERS MADE FOR INDEPENDENT CLIMBERS. FOR DECADES, THESE CHAMBERS HAVE BEEN PART OF COMMERCIAL MOUNTAINEERING – HEAVY, COMPLICATED AND VERY EXPENSIVE – BEING ALMOST A THING OF LEGEND THAT MOST HAD HEARD OF BUT VERY FEW HAD EVER REALLY USED, AND CERTAINLY NOT UP AT THE POINT OF CRITICAL NEED WHERE DEATHS ARE STILL REGULAR OCCURRENCES, DESPITE THE ENORMOUS INFRASTRUCTURE NOW IN PLACE.
THE INITIAL DESIGN CONCEPT CAME FROM NEW ZEALAND ALPINE TEAM MEMBER, MATT SCHOLES, WHO SAW A NEED FOR A SAFETY MARGIN TO BE USED ON OXYGENLESS ASCENTS IN THE HIMALAYAS. MATT IDENTIFIED THE NEED FOR A SOLUTION THAT WAS LIGHT, USEABLE AND CHEAP ENOUGH FOR ANY CLIMBER TO HAVE WITH THEM, TO PUT THEIR SAFETY INTO THEIR OWN HANDS IMMEDIATELY AS NEEDED.
ALTI APPROACHED FEEDING THE RAT EXPEDITIONS TO DEVELOP A CHAMBER FOR GENERAL AVAILABILITY, TO WHICH WE BROUGHT THE PROTOTYPING, DESIGN AND TESTING CAPABILITY WE HAVE USED WITH OTHER THINGS MADE SPECIFICALLY FOR HIGH ALTITUDE ALPINE STYLE USE. WE DEVELOPED SEVERAL VERSIONS FOR VARIOUS NEEDS (WATCH THIS SPACE IN 2026), COLLABORATING WITH SPECIALISTS IN MATERIALS, PRESSURE METHODOLOGY AND INFLATABLE TECHNOLOGY, TO MAKE THE FIRST ‘ALPINE GRADE’ ALTITUDE CHAMBERS AVAILABLE.
AND HERE THEY ARE. THIS CHANGES EVERYTHING.

MANUFACTURED IN POLAND BY MROZY USING PROPRIETARY MATERIALS, THESE CHAMBERS ARE AT THE FOREFRONT OF INFLATABLE TECHNOLOGY, AT THE HEAD OF A CURVE THAT IS CHANGING EVERYTHING FROM PACKRAFTS AND INSULATION. PAIRED WITH DEVELOPMENTS IN MINIATURE PUMPS THAT REPLACE OLD AND SLOWER METHODS, MROZY’S UNDERSTANDING OF INFLATABLE TECHNOLOGY MEANS THE CHAMBER CAN BE PRESSURIZED WITHIN 2-5 MINUTES TO SIMULATE DESCENT THAT WOULD TAKE DAYS.
MROZY MAKE BY FAR THE LIGHTEST FULL SPEC PACKRAFTS AVAILABLE – ONES WE ARE TAKING TO THE KARAKORAM – BUT THEY ALSO PRODUCE HIGH SPEC MOUNTAIN SAFETY AND MILITARY EQUIPMENT. THESE CHAMBERS ARE MADE TO EXCRUCIATING DETAIL TO ENABLE THE HIGH PRESSURES INVOLVED. THE GEOMETRY, MATERIALS, CONSTRUCTION, FITTINGS, TOLERANCES AND ERGONOMICS INVOLVED ARE DIGITALLY MODELLED AND TESTED IN REAL USE, WITH MODELS GOING OUT TO THE HIMALAYAS WITH ELITE POLISH CLIMBERS, AND OUR OWN EXPEDITIONS TO TIBET AND THE KARAKORAM AS YOU READ THIS.

WHAT YOU NEED TO KNOW
THESE CHAMBERS ARE SPECIFICALLY FOR ALPINE STYLE ASCENTS, WHERE ALTITUDE ISSUES ARE RELATIVELY SLOW ONSET, OPPOSED TO THE RAPID ONSET OF SUPPLEMENTAL OXYGEN FAILURE. THE 10kpa PRESSURE REPRESENTS DESCENT EITHER TO A BASECAMP OR TO AN ALTITUDE THAT IS NATURALLY ACCIMATIZABLE, AND IS TEMPORARY MITIGATION FOR THE EFFECTS OF ACUTE MOUNTAIN SICKNESS BUT DOES NOT SUBSTITUTE FOR ACTUAL DESCENT OR MEDICAL INTERVENTION.

THIS IS EXCITING STUFF WITH THE POTENTIAL TO CHANGE HOW HIGH ALTITUDE CLIMBING WORKS FOR BOTH COMMERCIAL AND INDEPENDENT CLIMBERS. AS LIGHT AS A BIVY BAG, THE ALTI CHAMBER BRINGS A SAFETY MARGIN TO THE HIGHEST CAMPS ON ANY PEAK, FORMING A CONTINUOUS CONTINGENCY ELEMENT FOR ANYTHING AT ALTITUDE FROM THE APPROACH TO 8000m. IT ALSO HAS UNTAPPED POTENTIAL FOR ALTERNATIVE ACCLIMATION STRATEGIES WE WILL SAY MORE ABOUT IN THE FUTURE.
ALL OUT TRIPS TO HIGH ALTITUDE HAVE CARRIED THESE FOR THE LAST TWO YEARS, GETTING REAL WORLD USE IN TIBET AND THE TRANS-KARAKORAM ON SELF-SUPPORTED EXPEDITIONS, BEING USED DOWN TO -25c.
