GildanLarge Men's DryBlend Classic T-Shirt

Looking to use these for heat transfer. Do they still need to be preshrunk since description says it's 50% preshrunk cotton?

Do these bleach well for bleach designs?

The shirt says its 50/50 poly/cotton. Does it feel like a normal cotton shirt, or does it feel more like a jersey? I am looking for normal shirt feel.

I like a shirt with a collar that is a bit smaller and higher (covers my neck a bit more than most). Will the collar on this shirt do that?
