Just visited Coogee Beach in Sydney and saw many of these shelters called CoolCabanas. They are designed so you can enjoy the beach without sunburn, ageing, and skin cancer being rated for UPF 50+ protection.
They come in a compact travel bag and only one person is needed to set one up.
In addition to its Brisbane headquarters, CoolCabanas now has distribution centres in the US and the Netherlands.
