i have not completely used all the t-shirts i bought i have worn one and it was comfortable and set off the one of the short sleeve shirts that i also bought from ll bean. the day that i wore the t-shirt was a cool day and it help keep me warm.
These shirts are perfect for me as a PE teacher. I wear them for those in- between days, weather wise. They add just enough warmth when I don't want to put on a sweatshirt. The shirts hold there shape and don't shrink. Wish they'd come in more softer colors.
