We recommend comfortable clothing and shoes suitable for a walk in nature, depending on the weather conditions on the day of the flight.
It is usually warm during the flight itself, but it’s a good idea to bring an extra jacket for after landing, when the temperature drops quickly and it gets a little colder.
It is a good idea to bring a cap/hat to protect against the radiation from the balloon’s burner. On warm days, it is also important to bring extra fluids, such as a bottle of water. Sensible shoes are especially important as you risk ending up on damp and uneven ground upon landing.
