ProThera Pro is a true compression fit. It's meant to feel tight going on, that's what does the work. The compression panels are what flatten and hold.

Order your normal t-shirt size. True to size, S through 3XL.

Between two sizes? Size up for all-day comfort under a work shirt. Stay for maximum compression and the tightest silhouette.

The first few minutes feel snug. That's normal; the fabric warms up and moulds to you within about 10 minutes.

Most guys don't have a diet problem. They have a right now problem — a wedding on Saturday, a work event tonight, a shirt that fit fine last year.

ProThera Pro is built with targeted compression panels across the chest, midsection and lower back. It smooths the shirt line, holds the midsection flat, and pulls your shoulders back so you stand taller. Under a t-shirt, a dress shirt or on its own — the difference is immediate and nobody can tell you're wearing it.

What you'll notice:

• A flatter, sharper silhouette from the first wear
• Chest and midsection held smooth — no shirt cling, no rolls
• Shoulders pulled back, so you stand straighter without thinking about it
• Sweat-wicking, quick-drying fabric — wear it to the gym or all day at work
• Four-way stretch, so it moves with you instead of riding up

Machine washable. Holds its compression wash after wash.

Try it for 30 days. Wrong size, we swap it free. Not for you, full refund. The only thing you risk is finding out what you look like in it.
