Product Details

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.

  • 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 V-Neck styling for use with polo shirts, t-shirts, casual shirts and business shirts when you want to wear them unbuttoned. Prefer Crew Neck? See our Crew Neck shirt

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

    Undershirt power

    Great product, and fit. The undershirt does what it said that it would. All I need is a big S stiched at the centre in red and blue....

    10/10 would recommend

    I sweat a lot more than the average person (to the point where it could be a 14 degree (c) day and still have sweat patches as though it is a 35 degree day) and so far I have been finding that these shirts mitigate that completely while also being super comfy to wear! I am definitely going to get some more when I need replacements.

    Undershirt is very good but….

    I struggle from hyperhydrosis. I have a really really bad case of it and my underarms sweat through anything but the this undershirt. I love it. It’s been a week and I still need further testing but it’s been the best time of my life since before I sweat like this. I’m a teenager and the bullying is insane. Not anymore. But the only thing today I got very close to sweating through the undershirt and I’m hoping it was a 1 off or I was wrong. It felt damp only slightly. I’m hoping it was just the feeling of my body heat because it gets very warm there. If you guys can please try and make it even more stronger to sweat through that would be great and I’m praying it was just body heat. Thanks soo much guys and please try your best to improve the product so it can be a full star review and even the worst cases can be comfortable in the product

    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.
