Long Sleeve T-Shirt FAQ

A shout-out to the manager who actually keeps things running smoothly. The clean, bold design that says "Best Boss Ever" makes it a solid choice for employees who want to show workplace appreciation.

100% cotton (Heather is a Cotton/ Poly blend). Pre-shrunk. Slightly heavier than our t-shirts but ideal for a long sleeve tee. Sized for men but can look great on women!
