How it fits
Closer's Undershirt Size & Fit
Built to disappear under your shirt.
The Closer's Undershirt is cut to help stay flat, stay hidden, and stay in place under tailored clothing.
Keep the lines clean.
A trimmer fit helps reduce bunching and keeps the layer sitting closer to the body beneath a dress shirt.
Find your size
Use your chest measurement as the primary guide. Your typical dress shirt size is included as a quick reference.

Materials & Care
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

Care instructions:
Machine wash cold with gentle detergent.
Do not bleach.
Hang dry or tumble dry low for best results.

Like any hardworking piece, check in every few quarters.
