I screenprint and am pretty anal about what print on, I won’t sell rubbish even though I’d make more and most punters would not notice.
Fotl are awful for shrinking. Of them the heavyweight ones are best, the regular are paper thin.
American apparel, prob 4x the price of a fotl heavyweight at wholesale, are lighter material, about 145 I think vs 185 form a fotl, but more fitted cut and wear beautifully. My shirt of choice, but people won’t pay for them.
Best for quality and price imho are gildan 5000. Heavy material, good fit and good wash. Same price as fotl heavy, I use these for all my regular stuff.
I can recommend an excellent hoodie too if you need some.
