One thing I noticed about LLBeans long sleeve tee shirts, the sleeves come very long. When I first try them on if they are too long I wash in warm and then dry on high for about ten minutes. They will shrink up if you want them to, if not, dry on low. But you must order one size larger if you plan to shrink. It took me awhile to figure this out but now I have the sizing down. The vee neck pima cotton is very soft and thin, perfect for layering or a 60 degree day.
