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.

    They work perfectly

    I sweat pretty easily and have to walk uphill to get to my university campus so these are perfect to wear under shirts or jumpers to stop me from getting embarrassing sweat patches!

    Used these since 2016- hyperhidrosis

    I suffer from hyperhidrosis and these have been amazing, I can work without feeling paranoid about my sweat patches, I can guarantee after working in a hot summer kitchen for 8 hours there’s not one mark of sweat on my grey t-shirt it’s amazing! 10/10 well worth the money

    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.
