Dr. Carl Lee
" I am quite certain that the passive and active use of your altitude simulation equipment made a tremendous difference. You can only exercise at 20 000ft in your own home with your equipment! I am confident that your equipment increased the safety margin as well as the ease of the climb to the summit as other climbers suffered from altitude sickness. I hope you remember us with this summit photo! "

"Training with Altitudetech's system helped me get to the top of the world at 69 years old. Plain and simple, it did more than just prepare me for the world's tallest peak, it helped me get there faster, stronger and safer. Couldn't have done without it!"

“I definitely felt the benefits of using Altitudetech’s portable Altitude chamber as a training tool to aid in my endurance activities. I believe the system would benefit any climber going to high altitude if used beforehand and in the proper manner, possibly eliminating time spent acclimatizing during the approach or while at base camp on long expeditions.”

2 ascents of Mt. Everest, (2006 and 2009)
136 ascents of Mt. Rainier

5 expeditions to Aconcagua
Dr. TA Loeffler
"I led a team to Kilimanjaro in January, we got all 10 of us to the summit. After using your equipment to pre-acclimate, I can say for certain that we had an edge. All of our saturations were higher throughout the climb. Thanks!"

"I got back on June 18th from Everest. I did very well. I left Base camp at 05H30 in the morning and was at Camp I at 10H15 and at Camp II at 14H30, one hour before my climbing sherpa! Then I went to Tibet, India and Tanzania where I climbed Kilimanjaro up and down in 2 days! Your system prepared me for all of this. Thank you!"

Saad Naseer
"I had no symptoms till 20 000ft on my last climb after using Altitudetech's system. I'm VERY confident that I'll be able to do Everest in 4 weeks compared to the regular 8 with this technology and your equipment. THANKS!"

"I had a Medtronic Freestyle aortic valve implanted a few years ago and I appreciate the technology and science. Altitudetech definitely has the technology and knowledge to pre-acclimate any climber to altitude right at home thus keeping them safe from HACE and HAPE."

Dr. Michal Bardecki
"Using the Altitudetech sleep and exercise system 2 months prior to our departure to Aconcagua 22,829ft/6,962m), prevented any symptoms associated with altitude sickness. At 4400m, our guide didn't believe that our oxygen saturations were still 99%! Thank you!"

"Things are going great in Peru, 3 climbers went from Lima which is at 0 meters to the Summit of Ishinca which is at 5600 m in 4 days, unbelievable! Pre-acclimation using your system is working really well."

"Thanks again for helping me summit Longs Peak (14 259ft) with no altitude sickness whatsoever. On previous ascents to 14 000ft I have suffered from headache and nausea. On this trip I was able to fly from sea level on Friday afternoon, drink gallons of Vodka and Redbull and then head out to our base camp at 10 000ft on Saturday night. We started our summit attempt at 0430h on Sunday morning summiting at about 1130h. The three guys I was hiking with all live in the Denver area and are acclimatized to about 5-6 000ft. I had no trouble keeping pace at all and in fact could of went a lot harder. I didn't tell them about the tent until after the climb, they were blown away at how strong I was. I would recommend this type of training for anybody who lives at sea level and plans on doing anything strenuous at high altitudes.
Other positive effects that I noticed was that my pulse dropped about 10 points from around 60 to around 50, I also experienced an increase in the number of reps i could perform at any given weight when I was at the gym. If you are experiencing a stale period in your gym workouts this might help you put some added power and fun back in your workout. I also notice that when I was running I was more interested in increasing my intensity and that when I stopped running my breathing normalized very quickly. I plan on using a tent again to prepare for my Kilimanjaro climb."
