The Original, and Still Our Best Seller.
Sweatshield Undershirts started with the classic V-Neck undershirt, and we're still making them more than 10 years later.
Our V-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.
Luxurious micro modal fabric, which is 50% more absorbent than cotton, ensures that perspiration doesn't end up as sweat marks. This works on the entire shirt, not just the underarms.

No deodorant stains or sweat stains means that your outer shirts last longer. You'll save money on and stop stressing about the shirts you show the world.
