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.

    Great , but is there a version with the back protection but not the underarms

    I find the underarm pads a little uncomfortable. And anyway I only have the sweating problem with my back


    Used at a wedding. Happy as!

    Fantastic! Have revolutionised my working life

    No longer do I have to wear jackets or jerseys in stifling weather to cover 'armpit leakage'. These shirts stop 90% of pit stains, and are comfortable to wear! Back sweat shield works on all shirts, and armpit padding has worked on all shirts except two tighter shirts. One small gripe - shirts that are a bit 'tight' around the armpit still show small 'sweat stains', probably from constantly rubbing against the underarm sweat pad, but no wear near the size they used to be! I will happily be purchasing more of these shirts.


    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.

    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.
