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.

    I'm a Paramedic, so getting sweaty is almost guaranteed. This undershirt keeps me dry and cool, but most importantly, comfortable. Would certainly recommend.

    A must have for the office

    I sweat more than anybody I know and especially when In a shirt and tie in a busy stuffy office. I wouldn’t be without my sweatshield vests, not a drop of moisture gets through!

    Sweat shirt Undergarment

    Smashing. Does exactly what it said on the tin. Shirt underarms completle dry during the day and very discreet. 5 not enough if your wearing every day so I suggest 10 (I'll be buying at least 5 more)


    These t-shirts are perfect. No more sweaty patches on my shirts and they are comfortable.


    Great product! For years I've had to deal with sweat stains. Used all types of undershirts and none worked well , until I found this. It really works so it is worth the money. Thank you


    I've been using these for a few years now and they are very effective


    I previously left a review saying how good I find your shirts. My view hasn’t changed. However, would you make a version where the arms come down to the elbow. The current arms end over the middle of the bicep, the largest part of the arm, so it is obvious that one is wearing a T-shirt. If the arms finished at the elbow the T-shirt will not be visible. This would lead to a cleaner silhouette.

    As good as

    As good as any other similar product on the market

    Thank you, Hillary! We believe we have the best sweatproof shirts in the world. We are glad you like them!

    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.
