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.

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

    Comfortable and totally works

    I'm super happy with my shirt. The material isn't heavy and keeps me cool, nobody can tell I'm sweating, and I just feel better all day. It's awesome. Thanks Sweatshield!


    These under tee's are awesome. My work shirts are normally soaking at the back and under the arms. Now they are bone dry even in the hottest room, and driving my car with the leather seats which normally cause the same problem. I bought 5 and have now ordered another 10.

    Full of confidence

    Purchased 2 off the Mens White Sweat Proof Undershirt V Neck shirts as had to stand for two days on an exhibition stand fully suited and booted

    Great product, no more sweaty armpits

    Works 100% at keeping sweat from reaching your shirt. No matter how hot I get these undershirts work, this is my second purchase. I bought a small and it fits nice and tight but it's stretches so very comfortable for all day use (I have a 40" chest). An essential item in my wardrobe now would not wear a shirt without one underneath. Also it's breathable so you don't overheat wearing it even in summer. If you want sweat free shirt armpits just buy this product, it's fantastic.


    Does exactly what it says, keeps you dry absolutely amazing product would recommend to anyone who suffers from those embarrassing under arm sweat patches.

    It's incredible!

    It's a wonderful product.
    This shirt has solved the sweat issue in a great way.
    Thank you very much!

    Simply the best

    I was definitely sceptical about any product that claims to do what this can as I have been let down in the past. However I can honestly say that this works. I will be purchasing the special offer of 5 with 35%. Although not particularly cheap, it is worth every penny. I'd go as far as to say it's a life saver.

    Worth the money

    I've been using normal v-neck skinny fit t-shirts for years. They all needed replacing recently and i decided to upgrade and give these a go instead. They're amazing! Yes they are expensive but I guess this is due to the fabric and extra labour costs involved in the manufacturing process. Worth every penny.

    confidence booster

    I don't think I need to explain what the title says. Please try it and you would know. No more sweaty armpits as it doesn't allow sweat to site on your shirt. Perfect for winter and sumber.

    putting the undershirt on is like putting confidence on

    For me I have tried using all the different deodorants with no success and it was affecting my day to day life. Black was my favourite colour t-shirt. I'm actually able to wear different colours without having to worry about pit stains and can actually enjoy myself. I never white reviews but this product is a life changer and people need to know it
