How it Fits
The Closer’s Undershirts is cut in a way to help stay flat, stay hidden, and in place.
| Go with | Your Chest (in) | Typical Dress Shirt Size |
|---|---|---|
| XS | 32–35 | 13–13.5 |
| S | 35–37 | 14–14.5 |
| M | 37–40 | 15–15.5 |
| L | 40–43 | 16–16.5 |
| XL | 43–46 | 17–17.5 |
| XXL | 46–49 | 18–18.5 |
If you’re between sizes, we recommend choosing the smaller option. A trimmer fit reduces 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

Momentum™ begins with modal-rich fabric chosen for its smooth, soft feel. Added stretch allows each garment to move naturally with the body.
Your foundation is handled.
A well-built wardrobe begins before the shirt, trousers, and jacket. Momentum™ creates a dependable starting point for workdays, weekends, and travel.
Made for the rooms that matter.

Dress to your own standard.
The first layer may be private. The standard behind it is not.
Ready for what comes next.
Momentum™ cannot close the deal, lead the meeting, or make the flight. It can give you a comfortable, considered foundation for doing it yourself.

Move with intent
Flexible, lightweight, and designed to flow with you so nothing holds you back.
