Easy to use.
The Hot Yoga Dome inflates in 60 seconds. Plug in your heater and humidifier and before you're even changed into your yoga leggings it'll be hot and humid.
When you're finished, pack away in under 10 minutes. If you're feeling super zen, don't even roll it away. You can leave it ready for tomorrow's practice.
Think of the time saved from going to your studio. Added bonus: No line for those cold showers.
