Absolutely excellent sweat protection and durability
The fit great. I’m a sweaty person, and while my back and front May get sweaty, my armpits remain dry. Been using for over a year with regular machine washing and they work as well as when they were new. The body is very light and cool and it is comfortable for even 14 hour days. Worth every penny spent and I recommend these to any person I meet who complains about armpit stains. I use them for work which is 12 hr days, 190 days a year.

Better than my Thompson Tees!
Softer, better fit, and more durable than my Thompson Tees. I was a little nervous about buying an off brand but I’m marking this in the “W” column!

Beware of Overheating; Otherwise, Performs as Described.
The shirt fit and performed as expected. No sweat made it to my dress shirt; however, be aware that this shirt does not breathe. If you are wearing a full suit and using this as an undershirt, you will get VERY hot. The body sweats to help cool itself, thus wearing this shirt and not allowing your armpits/torso to breathe can make you very uncomfortable or worse, a heat casualty. I wore this undershirt to a military formal under my ASUs (think tuxedo) and my date kept asking me if I was hot/okay because my face was so red. I have a love-hate relationship with this shirt as a result and will have to keep in mind environmental factors to cater wearing this shirt only when necessary/possible to prevent overheating.

Game changer. This is the brand that knows what they are doing.
These are truly amazing. Life changing really. Opened up my wardrobe and can now where light blues, light greys, and all kinds of colors other than black. Never have to use towels from the restroom to dry your shirt in the middle of the day or deal with sweat stains again. Best brand I’ve found. Great quality, work awesomely, hold up well. I now wear them almost everyday.

FABULOUS Shirt- This actually works!
I took a chance and purchased this for my teenage son. He is a sweater. Not "pull the string as I walk away" sweater to keep you warm (ha), but a major waterworks sweat shop sweat-er. When he's playing sports, he deals with it, but doesn't like wet stains on his shirts just from walking down the hall at school. I handed him the package, and said "Let me know what you think". After busting out laughing at the appearance of the shirt itself, he gave it a try. INCREDIBLE!! This product does exactly what it was designed to do- it stops any sweat from making it thru to your regular shirt. Out of the package, it looks a little funny as the arms are heavier than the rest, but the fit is great and the arms don't sag when it's on. The fabric is soft and slick, much like the athletic shirts out there that have "underarm" in the name but don't have the same underarm protection. The extra layer under the arms is not so thick as to be uncomfortable, and it doesn't "crunch" or make noise. My son says he didn't notice the extra layers after a bit, and he is SO pleased that this works!!! Much better option than antiperspirant that does not allow your pores to breathe. I just ordered another, and will no doubt be purchasing a few black t-shirts for the fall. Older son is going to want some, too... THANK YOU, Ejis!!!

Gives confidence...but costly.
Today I wore Ejis for the first time and I sweated more than usual. I was constantly checking to see if my sweat showed through my shirt. You see...today was my first day back at school as a teacher. I chose my first time wearing Ejis for an occasion as today. I did not see one single sweat stain seep through my shirt. So far, I absolutely love the Ejis shirt. I do wish they were not so expensive. I know I’m buying quality and it is fixing a hyperhydrosis issue I have had for nearly 20 years. I bought two shirts at 72 dollars. This is more expensive than any other clothing article I own. I did tell my wife today I would buy three more so I can wear one every work day. I actually chose Ejis over any other because I thought I was buying 3 at 36 dollars. I was surprised to find when they arrived that it was only one. Because my hyperhydrosis is so intense I decided to try it out anyways. I’m satisfied with Ejis doing exactly what it said it would. I’m not satisfied with how much they cost. I will be referring this product to one of my cousins who also has hyperhydrosis. Thanks Ejis for making such a good product!

Only worked the first day…
I wore this shirt once and it worked well. Had all the confidence in the world to wear a light colored shirt the next day and BIG MISTAKE. Was embarrassed like crazy at work with huge armpit sweat marks. I thought maybe it was a fluke and tried it out a third time (that’s where the pictures attached a from) and still no luck. I wanted to try something different than the Thompson Tee. Was excited for this shirt because of how superior the feel and look is but it looks like I’ll be going back to TT now smh. Pros: Fit of the shirt, tightness around neck, ability to tuck shirt in without it hanging out/ lookin sloppy, and softness of fabric. Cons: Did not block sweat past the first day used.

Saugt Schweiß lange und zuverlässig auf, auch nach mehrfachem Tragen ohne waschen kein Geruch. Fällt groß aus

Ayant déjà acheté d'autres t-shirt de cette marque, je peux déjà en attester une très bonne qualité, avec pour seule défaut le fait d'être généralement très juste au corps même pour la taille sensée être la bonne, ce qui n'est évidement pas le cas avec de l'élasthanne et ce qui m'aurai éventuellement permis de faire des économies sans risquer d'abimer le tissu, malgré un prix légèrement plus élevé. Pensant également que cela implique logiquement une plus longue durée de vie du produit. Qui est ainsi bien plus agréable à porter.

Amazing product, stops all underarm sweat patches coming through to your shirt and you don’t get the horrible cold clammy feeling when it starts to dry. Recently changed jobs to an office where the older members of staff demand the heating on no matter the weather, these t shirts are an absolute live saver!

Such a great product. Not only did it help with my sweat spots but it is also such a comfortable material and the fit is great too. Already purchased another one!
