I do not have much experience in shirts/hoodies.
But I have recently been purchasing promo materials from h5promotions.com
The owner of the store is very helpful and responsive by call or e-mail. And he will send you a proof to approve beforehand of the item, location, and size.
The store website itself looks a little barebones, tbh. But he has an amazing selection of items on there compared to anywhere else that I've looked ( short of Alibaba and ordering 5000 units )
Most places online you can request a free sample of promo items to check the product out firsthand, I'm sure the same would work for shirts and hoodies.
For your order it might be worth it to go to a local print shop. Most of them print shirts and apparel at stores, but send off for the other items you can order through them.
So you'll be able to at least see how the material looks and feels beforehand.
Best of luck
E: Not sure what you consider bulk, hope it helps though.
