Meet FEELRIGHT SweatShield

Sweat protection starts with your first layer

An ordinary undershirt can get wet without keeping your outer shirt dry. SweatShield combines moisture-managing fabric across the body with extra underarm absorption, all in a lightweight, flexible layer that moves comfortably with you.

Catch sweat before your clothes do

The body fabric absorbs everyday perspiration across your chest and back, helping reduce the moisture that reaches your outer shirt.

Add protection where an ordinary layer falls short

SweatShield’s built-in underarm panels absorb moisture into the pad itself, adding dedicated sweat protection between your skin and your outer shirt. They catch your sweat before it soaks through and becomes a visible mark you spend the rest of the day trying to hide.

Extra protection shouldn’t mean extra heat

FEELRIGHT is designed to protect your clothes while keeping you comfortable as you go about your day. Lightweight, breathable fabric and low-profile underarm panels give you added protection without the heavy, restrictive feel you might expect from a padded undershirt.

Work shirts

I wear a white button down most days and used to keep my arms close to my sides to cover up. Not really thinking about that now which is nice.

Wasnt expecting much

Honestly thought it might be another gimmick. Wore it to the office yesterday and my shirt looked a lot better by knock off time. Pretty happy with it!

PROTECTION YOU NEED. COMFORT YOU WANT.

Protection without the padded look

SweatShield is built discreetly into your undershirt, helping protect your clothes without adding bulk or drawing attention to what you’re wearing underneath.

Put it on. Forget it’s there.

Soft, lightweight fabric sits comfortably against your skin. Designed for all-day wear, FEELRIGHT makes sweat protection a part of your day you barely notice.

Room to breathe. Freedom to move.

Protection shouldn’t mean feeling hot and bundled up. FEELRIGHT combines lightweight, breathable fabric with flexible stretch, so you can move comfortably without feeling wrapped in another heavy layer.

Get dressed. Stop readjusting.

Walking, reaching and moving around shouldn’t leave you adjusting and retucking your shirt all day. FEELRIGHT is cut with extra length to help keep your undershirt tucked as you go about your day.

A few things you might be wondering

Get to know your new underlayer

How is FEELRIGHT different from a regular undershirt?

FEELRIGHT combines an everyday undershirt with built-in SweatShield protection. The body fabric absorbs everyday perspiration across your chest and back, while dedicated underarm panels provide extra absorption where sweat marks are most likely to show. It helps protect the shirt everyone sees while you continue to sweat naturally.

Will it work if I sweat heavily?

FEELRIGHT is designed to give you extra protection when an ordinary undershirt isn’t enough. SweatShield adds dedicated absorption at the underarms to help catch sweat before it reaches your outer shirt.

Where does the sweat go?

Moving sweat away from your skin is only part of the job. Your undershirt also needs to help keep it from reaching the clothes you’re trying to protect. SweatShield’s underarm panels capture and hold moisture inside the undershirt, while the lightweight body fabric helps manage everyday perspiration across your chest and back. This helps keep sweat in your first layer instead of letting it become a visible mark on the shirt everyone sees.

Will another layer make me hot or uncomfortable?

FEELRIGHT is designed to give you protection without the heavy, restrictive feel you might expect from a padded undershirt. Extra protection is concentrated at the underarms, while lightweight, breathable fabric with stretch keeps the rest of the shirt comfortable as you move through your day.

Will it look bulky under my clothes?

SweatShield is built discreetly into the undershirt, so there are no separate pads to attach or bulky inserts to adjust. Its low-profile design sits beneath your everyday clothes, helping protect your outfit without drawing attention to what you’re wearing underneath.

Should I choose V-neck or crew neck?

Choose V-neck if you regularly leave the top buttons of your shirt open or prefer a lower neckline. Choose crew neck for a higher, rounded neckline beneath buttoned shirts, sweaters and crew-neck tees.

How do I choose the right size?

We recommend starting with our size chart to find your fit. FEELRIGHT should sit comfortably close to your body without feeling tight or restrictive. If you aren't quite sure, please contact us as we are more than happy to help out.

Can I still use deodorant or antiperspirant?

Yes. FEELRIGHT is designed to fit into your existing routine, so you can continue using your usual deodorant or antiperspirant.

Does FEELRIGHT help with sweat odors?

FEELRIGHT helps catch sweat before it reaches your outer clothing, reducing the moisture those clothes are exposed to. The undershirt itself still needs regular washing to remove absorbed sweat and keep it fresh. It isn’t a replacement for deodorant or normal clothing care.

How do I keep my undershirt fresh?

Simply wash it after wear and let it dry fully before wearing it again. Regular washing helps remove absorbed sweat, keeping your undershirt fresh and ready for another day.

Where do you ship?

We ship to Australia, the United States, the United Kingdom and Canada. Delivery takes 5–10 calendar days. Free shipping when you buy 2 or more shirts.

What if I order the wrong size?

If you’ve ordered the wrong size, contact us to discuss available exchange options.

How does the 30-day guarantee work?

Contact us within 30 days of delivery to request a return. You can wear and test one shirt from your bundle; keep the others unworn, unwashed and in their original condition. Return all shirts from the purchase, including the one tested, following our instructions. Customers cover return shipping under the voluntary guarantee. Read the full return policy.

Why choose FEELRIGHT over a cheaper undershirt?

A cheaper undershirt isn’t much of a saving if sweat still reaches the shirt you’re trying to protect. FEELRIGHT combines soft, breathable everyday comfort with built-in SweatShield protection where an ordinary layer can fall short. That means extra protection for the clothes you’ve invested in, and more freedom to wear them without planning your day around sweat marks.
