I used this for personal training, etc., but I'm selling it now that I no longer need it. There is no packaging, but it was purchased new and is unused. Since this is a used item, please inspect and check it yourself before using it for high-altitude work, climbing, etc. Use is at your own risk. I will also be listing some other items that I no longer use. If you purchase multiple items, I can ship them together and offer a discount.
