Taking the Original to the Modern Look.
We started with the classic V-Neck, and then our customers told us they wanted a crew neck, for both open-collared shirts and suits with a tie and a less-visible neckline.
Our Crew Neck undershirt with an impenetrable sweat-proof barrier in the underarm is the best shirt in the world for keeping sweat from showing through to your dress shirt, your polo, or your casual wear, whether you're making a presentation, going on a date, or just spending time with your family. Our technology stops sweat marks and keeps you cool, comfortable, and confident the entire day. These look and feel like a premium brand, and you can wear them knowing that you'll feel and look dry all day.

I was impressed in the quick turnaround from order to delivery. I used to order from the U.K. and delivery are two weeks. I am pleased to know that I can get these orders to me within days. Keep it up! Thank you!
I’ve been wearing these shirts for years, and there is nothing like knowing no matter what I’m doing that day, I don’t have to worry about sweating through my t-shirts, button ups or polos anymore!
I’m 6’2” 200lbs and wear a 42L jacket and the Large fits great. I personally like how the material fits and feels and suggest a little tighter fit to avoid feeling that drip!
These shirts are worth every penny imho, not to mention the $100s saved on not having to replace clothing due to staining!!!
Thanks for the amazing product! Customer for life!
These are the best shirts ever, aside from keeping the sweat from reaching my shirts these are the only shirts I have owned that stay tucked in. I will only be buying these undershirts from now on.
Ordered several shirts and the boxer shorts for my husband recently (he uncomfortably sweats through tshirts daily!) After trying a different companies product, we realized that these type of shirts do help. I read reviews of Sweat Shield, saw the buy 4 get 1 deal and decided to give it a try. He loves them! He says they are comfortable, form fitting, soft and get the job done. We will be purchasing again in the future.
Great product, I advise everyone who is looking for something like this to get this brand. You will never get disappointed.
As a sufferer of hyperhidrosis these work absolutely fantastic. Terrific for work undershirts
Love these shirts! Can raise my arms in the middle of a meeting without worry of sweat stains appearing. My confidence is back!
This product works wonderfully!!
Fantastic shirts. These are a life changer!
Like everyone who orders these things, I sweat a lot. I MC weddings and private events which means I do a lot of moving around in dress shirts. The underarm sweat was unavoidable and embarrassing so I tried these out. I literally can't believe how well these work. Let me tell you, I sweat a lot lol. My sweat stains were no joke but with these shirts they are non existent. I'll have to see how they hold up after washing but so far so good.
Men's Size Chart
Choose V Neck for use with polo shirts, t-shirts, casual shirts and business shirts when you want to wear them open collared (unbuttoned).
Choose Crew Neck for a sharp undershirt neckline with an open collared shirt. If wearing a buttoned up collar with a tie then crew neck will make the undershirt neckline less visible.
