Thompson Tee is a well-established name in sweat-proof clothing, and for good reason. The brand helped create the sweat-proof undershirt category and has helped a lot of people deal with underarm sweat stains. We respect what they've built.
But sweat-proof shirt technology has evolved, and the way pads are constructed and attached to the shirt makes a significant difference in how the shirt looks and where you can wear it. That's the core reason customers start looking for alternatives.
This article explains how sweat-proof pad design affects everyday wearability, how Social Citizen's approach differs, and what to consider when deciding which brand is right for you.
How Sweat-Proof Pad Design Affects What You Can Wear
Most sweat-proof shirts, including Thompson Tee, use a method called flat-sewn pad attachment. The pad is stitched directly against the underarm fabric across its full surface. This method is structurally simple, but it creates two visible outcomes:
-
Seam lines appear on the exterior of the shirt in the underarm area
-
The pad structure is detectable through the fabric under fitted clothing or in natural light
For a shirt worn strictly as a base layer under something else, this is manageable. The outer garment covers the seams. But it also means the shirt is only useful in one context: hidden underneath another layer.
This is by design. Thompson Tee is built and marketed specifically as an undershirt. Its fit, length, and construction are optimized for that purpose.
The limitation becomes apparent when someone wants sweat protection without the extra layer. In warmer months, in casual settings, or whenever someone wants to wear a t-shirt on its own, a flat-sewn undershirt isn't a practical solution.
How Social Citizen's Design Addresses This
At Social Citizen, we approached pad attachment differently from the start. Our pads are not sewn flat against the shirt fabric. Instead, each pad is securely attached on the inside of the shirt.
This design has two direct effects:
-
No visible seam lines appear on the exterior, so the shirt looks identical to a regular t-shirt, polo, or dress shirt from the outside
-
The needle connection points are closed off, preventing sweat from leaking through the attachment points when the pad is compressed against the body
The result is a shirt that functions as sweat-proof clothing but looks like regular clothing. You can wear it on its own to a dinner, a meeting, or a social event without it being identifiable as a sweat-proof garment. You can also wear it as an undershirt. The choice is yours.

Who Experiences Underarm Hyperhidrosis
It helps to understand the scale of the problem both brands are addressing. Axillary hyperhidrosis, the medical term for excessive underarm sweating, is the most common form of hyperhidrosis, affecting 68% of people diagnosed with the condition. In the United States, approximately 15.3 million people, around 4.8% of the population, live with hyperhidrosis.
For many people this means avoiding certain colors, changing shirts during the day, or declining social situations where visible sweat stains would be embarrassing. Before finding sweat-proof clothing, most Social Citizen customers had already tried clinical antiperspirants, prescription treatments, and traditional undershirts without finding something that worked reliably and looked like normal clothing.

A few of the recurring themes:
Already tried everything else
"I have tried literally EVERYTHING. I bought one white t-shirt to see what size I would be. Then after that was figured out and tested the shirt, I bought 8 more shirts in different colors!" — T.J., Virginia
"After trying countless remedies for both sweat and sweat stains, these shirts were the first and only product I've found that consistently and completely prevented sweat stains." — Anonymous
No visible seams or padding
"We've tried other sweat proof shirts but didn't like them because you could see huge panels or puffy seams. I love that this shirt has hidden panels — the underarm area looks like a normal shirt from the outside." — Cindy
"The brand tries to accomplish it looking like a regular shirt without showing the sweat pads. They do accomplish this." — Claire
Wearing colors and styles they'd given up on
"It was high school the last time I was able to wear any colour shirt besides black... these shirts are the only shirts I've ever found that I can wear with NO stains at all, and I am a VERY heavy sweater." — Anonymous
"I have hyperhidrosis and am on a medication that makes me sweat even more and these shirts are perfect. After hours out at bars I have no stains." — Reggie S.
