I responded to your order email but I'll say it here too.
We make shirts for normal people who work on their cars.. they are not cut slim.. they are heavyweight gildan 6.1oz 100% cotton and they don't shrink much if any at all. Results have varied with different batches or situations but that's just the plight of a t-shirt :) Anyway these things are really durable. I've burnt holes in them, cut them, torn them and I still have shirts I bought in this brand from 10 years ago that I wear in the garage all the time. That's why I chose gildan when we started this business.
