Product Details

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.

  • 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.

  • Keep-cool technology provides comfortable temperature control all day with lightweight, breathable material that still keeps moisture controlled. No sweaty cotton!

  • 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.

  • Classic Crew Neck styling for use with open-collared shirts, flannels and fleeces, and business shirts, and with a suit and tie for a clean, crisp look that will last wash after wash. Prefer V-Neck styling? Check out our V-Neck Shirt!

  • Tailored, stay-tucked styling keeps the shirts laying flat and the neck looking sharp, avoids bunching, and is tagless.

    Comfortable and dry

    The shirt fits great and is comfortable. It keeps sweat away from my clothes

    Good shirts

    The shirts are great. I’ve tired different shirts from other places and these are definitely a lot better. The only thing is I wish they came in 2x. If they offer them In 2x it would definitely be a 5 stars.

    Great Product!

    Great company with great customer service equals a great product!

    Works excellent!

    These work perfectly!

    It really worked

    Been wearing the undershirt the whole day everyday in 90 to100 degrees weather on very hot summer days and I never got wet or felt any sweat spots also it absorbed the odor so i never smelled like sweat way better than Thompson t and ejis that I have tried on Amazon.

    These are great!

    I bought these for my husband who wears a suit and tie to work every day. He would always have sweat marks on his button-down shirts, but the two days he wore these t-shirts his button-down was dry! The shirts are comfortable and stay tucked. A great find!

    No more soggy, swampy shirts!

    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.

    Great product

    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

    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.
