Mountain Air Cardio — Local Services | Serving Boulder & beyond

Mountain Air Cardio offers fully automated altitude tents for athletes to improve their  cardio performance and decrease their recovery time. If you’ve never tried an altitude tent, you can rent one from us for as little as four weeks. At the end of the rental period, you can decide to return the system to us or apply the rental amount you’ve paid  towards the purchase price. It’s a great way to try it before you buy it.
