Long Sleeve Cotton Work Tee with Chest Pocket
A long sleeve cotton tee in a heavyweight jersey, with a pocket on the chest and enough substance to be worn as a shirt rather than an undershirt.
The cotton is ring-spun and pre-shrunk, so it holds up to wear and tear and does not give up its length in the wash. A relaxed fit keeps the body easy through the chest and waist. Side seams stop the shirt twisting around the torso over a long day, and the main seams are top-stitched with a double needle where the strain lands. At the collar the neck seam is taped and the label is tagless, so nothing rubs at the back of the neck. The chest pocket takes the small things that would otherwise live in a trouser pocket.
This is a layer that works alone in the shoulder seasons and under a jacket in winter. Take the size you normally take; the relaxed cut does the rest.
