Extremely satisfied. I didn't think it was possible to keep my dress shirts as dry as these undershirts do. Thumbs way up! I'm ordering more very soon. – Joshua B.

    Awesome Shirt!

    This shirt is amazing and sticks true to its word, I work 12-14hr days in this shirt and used to have sweat stains so bad, but because of Ejis I no longer have to be self conscious about my underarms at work!! 10/10 recommend

    Style

    Product is freakin exceptional. Style � Crew shirt almost wears like a v neck. Not a true crew. Looks like a ladies top if I try to wear it as a regular top

    Surprised

    Having no to little sense of smell the presence of sweat undermines my confidence and stresses me out, leading to (you guessed it) more sweat. I tried the undershirt, somewhat sceptically, and rather than caking on an anti perspirent stick just plumped for a light body spray. Normally I would look like a reservoir had burst under each armpit so I was happy to report a dry shirt (and undershirt interestingly) and no one backing away (social distancing excepted) Thanks Ejis

    Never leave home without my Ejis

    I’ve bought probably 25+ of these over the last 2 years. Definitely a game changer and I wear one pretty much every day.

    Finally Can Stop Worrying

    I love it. I wear a suit every day in a retail environment, and I’m running around the store all day, even unloading trailers. You could see sweat stains in the armpit area of my suit. I was thinking about it every couple of minutes all day long. I wore this shirt the other day, and wow. I was nervous all the first time I wore it because I could feel I was sweating profusely, but every time I checked under my jacket, my dress shirt was completely dry! So happy I took a chance on this shirt. I wore it again today, and only thought about it a few times during my shift, which is a minor miracle. I could concentrate on my job instead of my potential embarrassment.

    The absolute best undershirt I’ve ever worn

    I have one on as a text this review! I just replaced all my under armor shirts I wear at work with these shirts. The comfort, feel and sweat protection is outstanding! I’m just waiting for my size to come back in the black crew neck so I can get a weeks worth of shirts. Thanks again for making a great product!
