My opinion:* The material is heavier than a t-shirt and comfortable to wear. Can be worn alone or over another thin short-sleeved shirt (my preference).* The 35% cotton, 60% polyester, 5% spandex blend offers just enough stretch, leaving plenty of room* I would classify this as "early-mid -Autumn" shirt (depending on where the person lives). It warms, but due to the weave does not protect against cold autumn winds. But I tend to have long arms.
