Men Short-Sleeve Undershirt

A short-sleeve layer that fits into your day

When you want sleeves beneath a button-down, polo or work uniform, reach for an Acacia men’s short-sleeve undershirt. Made from 100% cotton, it gives you an everyday base layer with more shoulder and upper-arm coverage than a tank. Choose your usual size and check the individual product page for fit and availability.

Find a color for what you wear over it

Explore white, grey, dark brown, dark navy and black. You might prefer a lighter shade under a light-colored shirt or a darker one beneath deeper tones. Each color has its own product listing, so you can check the available sizes before choosing.
