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.

The Ejist sweat proof crew necks have become my go-to undershirt for almost every occasion. I love how effective they are and the confidence I can have knowing my sweat won’t show through my shirts. Try it and you won’t regret it. The fit takes getting used to but I think it needs to be a little bit snug to be effective.

I have been dealing with this sweat issues for my entire life, even going to the extent to always wear two shirts and changing one mid-day. To deal with this situation, I tried every expensive deodorant on the market to no avail. Once I started losing expensive clothing to this issue, I needed to get serious. I knew they made pit pads and I was willing to accept a life of these, but to have a shirt that does everything for you could be a game changer. Thank god for Ejis. I purchased one from amazon, and by the end of the week I had two more ordered. A week later, I purchased four more to have enough to make it through the week. I love these shirts and will purchased another weeks worth of them down the road. My only complaint is the sleeves are way too short, which is my reason for four stars instead of five. If you have any sort of biceps (which I don't) the entire sleeve will end up in your arm pit or cut off your circulation. This should be an easy fix and is something that really needs to be altered. The short sleeve is so short that I'm sweating mid arm, which does appear to soak into the cotton. Also if you wear button down shirts of thin or silky material, sometime the moisture seeps through creating damp spots, but will dry quickly by moving the fabric away. In my experience this is short lived. Overall this is a fantastic product, keep an eye out for the sales and deals. The shirts are per-shurnk but I went a size bigger for comfort. In the future I would like a white or black long sleeve option. Thanks for everything you do!!
