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.

Men's Sweat Proof Undershirt (Crew Neck)
These are terrific! I sweat under my arms just sitting still, and before I found these, I was stuffing paper towels under my arms to keep from having embarrassing wet circles on my shirts, which were uncomfortable and had to be changed frequently. Now I’m free from that hassle. They also help keep the rest of my shirt dry when I’m doing light activity like walking around outside on a warm day. I like that they’re close-fitting so there’s no bunching under my shirts, and they mostly stay tucked in so I don’t show plumber’s crack when I bend over.
This is my 2nd purchase and I have enjoyed the fact I can wear this under my good clothes and not worry about ruining them. Only thing I wish is that the women’s come longer. I have a long torso so buying the men’s sizes adds to the length
New found confidence in the office . Try it!!
Amazing T-Shirt. I used to sweat through my dress suit and my suit coat. It was very embarrassing. Now, no one even knows the difference. The shirts are very comfortable.
Very good product. Would buy again. Also, the note from the owner was very nice!
I was skeptical but when i received I was blown away with the performance. I just do not like to have any sweat stain on a shirt and this keeps that from happening.
These undershirts are amazing! I bought these for my husband, who sweats so much, that he will not wear colored shirts because they leave huge sweat marks under his arms. These undershirts have finally allowed him to wear different colored shirts, without the embarrassing sweat marks. These undershirts are definitely worth the money.
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.
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.
