First, let me start by saying I have had confidence issues raising my arms for years, I have tried different deodorants, I have tried different shirts, I have tried Botox injections, I have tried everything. Until one day I stumbled across this product. I titled this too good to be true for a reason this is the one moment where too good to be true is actually 100% true. These shirts are next to incredible and I can’t begin to tell you the feelings I had the first time I was able to raise my arms without a sweat stain. Not only did I order the wrong shirts the first go round but I was able to get in touch with Wilbur who was absolutely amazing during the refund process and issuing me the shirts I actually meant to order. I will let you know right now I didn’t have a chance to check, but if they have black ones, I will be ordering those as well. This product has restored my confidence and being able to talk, hug whale my arms around, and not feel embarrassed or disgusted by the stains under my arms. I’m not gonna lie. I could’ve cried yesterday when I got home to tell my wife not only that I sweated my A** off all day at work, but not one thing came through. I am eternally grateful for these shirts and this product 100% sun up to sundown. As a matter of fact, I have already blasted this to a few friends who have the same issue, and they have already ordered theirs. Thank you so much for making this product available.

I have been dealing with sweaty pits for as long as I can remember. I bought my first shirts about a month ago, to try it out and it actually works. There is some seaping through around the chest area, but it's so insignificant that it doesn't cause a stain. I have ordered 10 more shirts, because this is an absolute game changer!

It kept me dry and protected better than any deodorant products that I used. I wore this undershirt last summer trip to Europe, and despite of few hours walk under the heavy sun with excessive sweat plus poses for photoshoot but sweat never see outside my dress shirt, nor any smell after a very long day. My wife very pleased with it.

I’m in my mid 40s and just started to have a sweating problem. Embarrassing sweat stains creeping through my shirts. I tried regular cotton undershirts, which absorbed the sweat, but were heavy and hot. I tried performance shirts, but sweat worse. I like bamboo, a lot, but can’t find any with the sweat absorbing pads. Then I found Ejis. They feel great, are light, don’t make me sweat through my clothes, and the sweat pads reveal absolutely NO stains. Embarrassment eliminated, confidence and comfort restored! I will be buying these for life.

I am happy with shirts but wish they still sold regular micromodel shirts without the underarm sweat protection. I am still keeping them.
