Summary: Polos that don't sit right, sweat you can see, feeling a little off out on the course. Turns out there's a simple fix a lot of golfers don't know about: wearing a compression tank under your polo. Keep reading to see why.

1. It Smooths Out Your Silhouette Under The Polo

Golf polos are fitted, and that means anything going on underneath shows. A compression tank sits close to the body and evens things out, so your polo lays smooth instead of clinging in some spots and loose in others.

You look sharper walking up to the tee, and you're not thinking about how your shirt looks all round.

2. It Helps You Stand Taller On The Course

The gentle hold of a compression tank makes you more aware of your posture. A lot of guys say they naturally stand up straighter and feel more locked in when they've got that support around their core, instead of slouching by the back nine.

3. It Keeps You Dry, Even On A Hot Round

Golf is a long day outside. Getting hot and sweaty by the ninth hole isn't fun, and it shows.

A compression tank is built to pull sweat away from your skin before it soaks through, so your polo stays drier for longer, even on a warm day walking 18 holes.

4. It Stops The Rub That Ruins Your Back Nine

A shirt that rubs against your skin for four hours is more than annoying. It can leave you sore by the time you get to the clubhouse.

A compression tank sits smooth against your skin instead of a loose undershirt bunching and rubbing with every swing. It's a small detail that makes a long round a lot more comfortable.

5. It Fits Smooth Through Every Swing

A loose undershirt bunches up the moment you twist into your swing. A compression tank is built from shaped panels sewn together instead of one flat stretched piece, so it moves with your body instead of fighting it.

That means no bunching, no shifting, no adjusting your shirt between shots. You just play.
