Hypoxic Training Tent - Maximum Altitude 7000m - For Cycling, Marathon, Mountaineering

Purchased several years ago for road cycling races. Original purchase price was ¥450,000.
Used for two seasons during sleep. I set it to an altitude of 2500m.
In the year I used it, my power output increased by a few percent, so I believe it is effective.
Total usage time is around 700 hours, which is less than one season's use for a professional athlete.

Selling due to moving and lack of space at home.
Includes a hypobaric tent (queen bed size, 160cm width) purchased separately for ¥80,000.
As I currently have no space to set it up, only sample photos are available.
There are no scratches other than the folding marks that were present from the time of purchase.

The operating noise described in the manual is 40db. Please note that it is not as quiet as machines in the multi-million yen class. While it did not disturb my sleep, please be aware if you share a room with others.

I believe this will be helpful for those aiming for records in endurance sports such as hill climbs, road races, and marathons.
Price negotiation is welcome, so please send a message.
