My t short drawer is overflowing, and mostly Penman's and their ilk. So have not checked the new brand you mention.
Usually a T shirt is in my life for at least ten years.
Once grungy, as an undershirt for work place collared shirts.
Once really grungy, kept to cut the lawn in or wear while change the oil in the cars, where a final fatal drip is a distinct possibility that it finally goes to the rags pile.
