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.

    Men's Sweat Proof Undershirt (V-Neck)

    Excellent Product!

    Absolutely worth the investment, a game changer!

    Absolutely fantastic product

    I cannot recommend this product highly enough. It's absolutely fantastic, and great value as well. In a small-but-meaningful way, this is life-changing!

    Peace and Security

    Finally I can go through the day and not have to worry about raising my arms or saving sweat from the pits to try and prevent soak through.


    Great product


    Fantastic shirts. These are a life changer!

    Been using these for years

    I've loved these undershirts since the first time I tried them. Great quality and they last a long time.

    Life Changing

    If you spend all day worrying that you’re sweating through your shirt, this is the product for you. I’ve been using them for years and nothing ever gets through, no matter how stressful the situation.

    Best on the market

    I’ve been buying these shirts for 5-6 years now and there is nothing better I’ve been able to find. The price seems high but they are very durable and will last far longer than a regular undershirt. But the key is that you will NEVER sweat through them. This means that your dress shirts (or t shirts or sweatshirts or whatever you wear normally) will never have pit stains. I mean that both in terms of being embarrassed during a meeting with a cloud or sweat on your garment but also in terms of long term maintenance of that garment. Pit stains are hard to get out and ultimately will ruin clothes. So with that, this is one of the smartest investments I continue to make and frankly if you sweat as much as I do, it’s one you can’t afford to skip.

    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.
