Closer's Undershirt Size & Fit
The Closer's Undershirt is cut to help stay flat, stay hidden, and stay in place under tailored clothing.
A trimmer fit helps reduce bunching and keeps the layer sitting closer to the body beneath a dress shirt.
Use your chest measurement as the primary guide. Your typical dress shirt size is included as a quick reference.
| Go With | Your Chest | Typical Dress Shirt Size |
|---|---|---|
| XS | 32–35 in | 13–13.5 |
| S | 35–37 in | 14–14.5 |
| M | 37–40 in | 15–15.5 |
| L | 40–43 in | 16–16.5 |
| XL | 43–46 in | 17–17.5 |
| XXL | 46–49 in | 18–18.5 |
Between sizes? Choose the smaller option. A trimmer fit helps reduce bunching under a dress shirt and keeps lines clean.
Some garments earn a reputation beyond their original name. Over time, our community began referring to our Sweat Stomping™ Shirt as the shirt they reached for before the interview, the first day, and the deal.
So while your garment will arrive with Sweat Stomping™ Shirt printed on the neck, you'll see it throughout our website as The Closer's Undershirt. The same garment, renamed for the moment it serves.
Composition: 95% Modal 5% Spandex
Origin: Designed in the US. Made in China
V Neck Collar
Available in White and Smoke Break Gray
Care instructions:
Machine wash cold with gentle detergent.
Do not bleach.
Hang dry or tumble dry low for best results.
Skip the iron.
Like any hardworking piece, check in every few quarters.
If the stretch fades, fit softens, or seams show fatigue, time for a fresh one.
