No problem Haluna. LAT apparel is not readily available in Australia, nor as well recognised as AS Colour. AS Colour has a strong retail presence in Australia with multiple stores in major cities, and also stocked by big brands/retailers.
Combed/Ringspun are similar - some brands use the term interchangeably. Both are superior to simple carded cotton.
The Bella + Canvas 3001 solid colors are 100% combed and ring-spun cotton (other color variants have different materials). And this t-shirt is available for Australian fulfillment (not all variants though). Baby and children clothing isn't available for fulfillment with our Australian partners. You can check this page for more info.
We'll automatically use Australian fulfillment for products going to Australia and New Zealand (for items that are available for fulfillment with our Australian partners). To check which items are available for AUS fulfillment you should look out for an "AU" label and you can also learn more here.
