Another idea could be to get them a new piece of kite surfing equipment, such as a high-quality kite or a waterproof action camera to capture their kite surfing adventures. Additionally, you could consider getting them a personalized kite surfing rash guard or wetsuit, or a kite surfing book or magazine subscription that they can enjoy during their downtime.
