Back in the day things were different.  This shirt may date you, but life was good back in the day.  A bit more formal than a standard-issue t-shirt, the ultra cotton long sleeve tee is a clear comfort winner. The sleeves also act as a nice frame. There are no side seams. The shoulders are taped for improved durability. This makes for a good fitting around the shoulders and neck. The cotton used for these shirts is environmentally friendly.
