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.

    As a sufferer of hyperhidrosis these work absolutely fantastic. Terrific for work undershirts

    Great Shirts and Return of Confidence!

    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!

    Can't Believe How Good It Works

    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.

    Excellent product

    These shirts are comfortable, smart and confidence boosting.They really do improve you're self esteem.No more marks on your shirts to try and hide.They give you the freedom to move.




    I think they‚Äö√Ą√īre great to hold the sweat in but the only downfall I would say is that it gets really smelly!

    Great Garments

    These undershirts are brilliant, do exactly what they say on the tin!

    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.
