Game changer
I will be buying more of these. Absolutely no sweating through them and ruining dress shirts. You have extended the life of my dress shirts and reduced the uncomfortable sweaty pits. The shirts do fir snug, so I may go 1 size up next time but they are very comfortable nonetheless.

These work!!
I was worried about them being so expensive. If you have excessive underarm sweat like I do, get this product. You will not be disappointed.

So So
These really do the work and keep you dry. The only issue is that the feel is a bit of a nuisance. It feels a bit sticky across your midsection throughout the day. It’s the material that causes that. I guess I’m used to cotton t-shirts. As for the sweat proof, these are top notch.

Amazing
I am incredibly sweaty and these have helped so much. I have taken to wearing these almost every work day. I can actually wear light colored shirts now!

Perfect!
I have literally tried every undershirt, out there ranging in price from $5 to $75. None of them helped with sweat at all except Ejis. Ejis micro module are the only undershirts I have purchased for the last 3 years. At any given time I have 20-25 of them. Where them everyday!

It Works!
These shirts are fantastic. They’re the only thing that really helped my husband. None of the fancy deodorant or washes or creams but these shirts that simply absorb the sweat without making it visibly noticeable.

Game changer shirts
I have been using this brand for years and would never wear an expensive dress shirt ever again without these. They did change the material from cotton to a lighter weight product, which I dont love as much. The new material seems to bite onto regular t-shirts and cause them to bind up with the undershirt a bit, but for dress shirts, they works like a charm. NO MORE SWEAT. Seriously cant overstate how these changed my life in tense meetings.

Pricey but fit as expected
These undershirts fit as expected and look as advertised. It is a bit Expensive, so that has to be taken into consideration when shopping around.
