I am a very heavy sweater and have awful hyperhydrosis on my back during any activity. These shirts have been a serious lifesaver! Nobody can tell I have such a sweaty back, and they hold up regardless of climate or what I am wearing. I have tried several other brands that claim to do the trick, but none have come close compared to this one. The customer service is also very friendly and prompt! I am now a lifelong customer.
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.
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.
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
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 :)
Being a medical student on placement I‚Äôm required to wear smart shirts on a regular basis. Unfortunately I suffer pretty bad Hyperhidrosis on my back - but these undershirts have done wonders for me! I can finally wear nice looking shirts without worrying that they‚Äôll change colour from sweat by the end of the day!
I purchased and have been using the men‚Äôs back sweat proof undershirts and they are fantastic. Comfortable to wear and do exactly what they should, stop any sweat coming through to outer shirt. Great product and I will be buying more in future.
I'm an extreme sweater. Eventhough I'm lean, I still break out in a sweat fairly easily. When wearing a wool wedding suit during a July wedding, it's just asking for trouble. I didn't want to look all drenched on my wedding photo's, so in a desprate attempt, I ordered this shirt. It had to be skin colored since my dress shirt was ecru (creme white). It was scorching hot all day and I sweated a great deal, but my dress shirt was never wet. I can truly say this shirt saved my wedding and I will endorse this shirt until my final day.
The brand works very well. It's a strange material to wear but it does the job.
I never have sweat on my shirts which is great.
The only thing I would prefer is if the underarm padding was thinner s this feels a little heavy and bulky.
I think If I wore a t shirt with this under it would look odd. Apart from a thinner version it works.
Haven't worn white ones yet but am sure same as the black ones, highly recommend. Confidence to wear any colour outer shirt/top and know it will stay dry, no embarrassing wet patches. Great product
Men's Size Chart
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.
