This product holds its shape well after being washed, treated, tie-dyed, and dried in a hot dryer. The sizes stayed true and the dyes took extremely well, like it always does; this is why we stick with the Hanes product, and have for years. This review is true for a total of 36 t-shirts, all turned out beautifully. This is important to my son and I, as we do this tie-dye event yearly as a contribution to our local county Maryland Special Olympics Swim Team. It is always a good time, to be able to work with these athletes for the evening and not have to worry about how the product will hold up. Thanks, Hanes!!
