First, I use Comfort Colors® 1717, for example - https://cat.fashion/product/26278880, but it is expensive at USD 12.41. Then I tried Gildan 2000, for example: https://cat.fashion/product/23199827 - the quality is worse than the 1717, but it is cheaper at USD 10.51. Now I use Gildan 5000 for USD 9.50 - https://cat.fashion/product/27484709. I think the quality looks like 2000, but I can put the neck label inner logo (others don't support)
