Product Details

Classic Look for a Better Day.

Sweatshield Undershirts invented and is still the only manufacturer and retailer of an undershirt designed and dedicated to helping with back sweat.

Our V-Neck undershirt with an impenetrable sweat-proof barrier in the back is guaranteed to stop sweat marks for even the most serious back sweaters.

Whether you suffer from hyperhidrosis, have compensatory sweating due to surgery, or just find yourself with more perspiration than you're comfortable with, we are here to help.

We've built 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.

  • Deep V-Neck design means the undershirt can be worn with an open collared shirt without being visible. The sweat shield forms an integral part of the back panel of the undershirt and is thin, comfortable and discreet.

  • Keep-cool technology provides comfortable temperature control all day with lightweight, breathable material that still keeps moisture controlled. No sweaty cotton!

  • Classic V-Neck styling for use with polo shirts, t-shirts, casual shirts and business shirts when you want to wear them unbuttoned. 

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

    Able to wear colored dress shirts with confidence and without a sweater or jacket with these undershirts! Ordered a bunch more as these are now the only ones I’ll be wearing.

    Sweatshield really has my back, and they’ll have yours too...

    Long history of excessive back sweating - nowhere else, it’s kind of odd. In any case, Seatshield’s product is the first tee shirt I’ve purchased from a vendor who specializes in keeping hyperhidrosis activity at bay. To that end, it’s lived up to its promise in my opinion. In me, they’ve gained a new lifelong customer. Many thanks for helping increase the quality of my life by markedly decreasing my vexing back hyperhidrosis.


    I just bought the t-shirts and they're terrific. No sweat was visible through my work shirt - I can finally wear any colour of shirt that I want. And they're quite cool too, i.e you don't over-heat in them. For an excessive sweater like myself they are worth every cent.

    Excessive back sweat

    Following years of many attempts to find cure, can finally thank sweatsheild for a product that actually works. Can now be comfortable in wearing shirt without perspiration marks. Wonderful new freedom, wonderful I do not have to worry about this problem. before/after photographs attached

    Thank you.

    Fantastic Undershirt - would recommend to anyone!

    Fantastic undershirts. Light and comfy with a tight fit so you don't even feel like you are wearing one. Also the v neck means you can have the top button undone and the undershirt is not visible. I have never had any sweat marks when wearing these undershirts. I couldn't recommend them more :)

    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.
