How It Works
Firm, stretchy nylon-elastane holds your chest and midsection in place, so shirts lie flat instead of clinging. The extra length stays tucked and does not roll up when you sit or move.

The Real Problem
Shirts Cling. Undershirts Roll Up.
Regular undershirts do nothing to smooth, and most compression shirts are too short for big and tall guys. So you tug at your shirt all day.

FAQs
Everything You Need to Know.
Plain answers to the questions we get the most.
How firm is the compression?
Firm but comfortable for all-day wear. It smooths your chest and midsection under clothes.
Will it show under a shirt?
It is sleeveless and smooth, so it stays hidden under tees, polos and dress shirts.
What does "tall" mean?
Extra body length so it stays tucked on tall builds.
Can I work out in it?
Yes. The fabric wicks sweat and stretches.
Which color should I get?
White or grey under light shirts, black under dark ones.
How do I wash it?
Machine wash cold, hang dry.
Can I exchange the size?
Yes, on unworn items within 30 days.
