@deemann1 - I notice you are in Ireland.
It appears that the ozarmour website tries to automatically guess which country you are from and changes the URL to match. For example:
https://ozarmour.co/en-uk
From the main Australian website (
https://ozarmour.co/) - you can select which country using the small globe icon (top right). Note "Change Country" is in small text.
When I change the country to Ireland - you are correct. Only the Khaki Poly Cotton seems available.
Use the "Contact Us" form to ask OzArmour if this is what they intend. When I used their contact us form they replied within 24hours.
