The material on these shirts is the softest I’ve tried, however the sweat guard is the worst in the market. Very quickly led to breakthrough sweat showing, when other comparable shirts would not show breakthrough. I was especially bummed given the price point for this shirt compared to other brands. If you are a big under arm sweater, go with another brand, two stars because the material is nice & I wanted to like it.

Hi Charles, Thank you for leaving a review. We are so glad your Ejis undershirts work so well for you. Best, Gigi Ejis Customer Support
I wore the V neck micro modal sweat prof shirt to an event in Denver,CO. The temp exceeded 100 degrees and we spent time in and out of the air conditioning. The shirt fit nice and snug in a good way. The V neck was perfect so it didn’t show. The winner was the sweat proof arm pits. I couldn’t even tell that I was sweating. Sometimes you can feel the sweat with the cotton versions. This one was great. I need to see if they make underwear with the same material!!! That would be another winner!!!!

I do love these shirts. I just wish it didn’t take so long to get them. I waited for months before they were restocked.

Exactly what I needed to gain my confidence back instead of changing shirts repeatedly at work. I no longer pit the shirts out. Game changer for me!
Hi Michael, Thank you for leaving a review! We are so glad that your Ejis undershirt has been a game changer for you. Best, Merrielle Ejis Customer Support
The t-shirts are excellent. My only complaint is that you run out just when I need to replace them.
Hi James, Thank you for leaving a review. We are so happy to hear you love your Ejis undershirts. We are working very hard to keep our most popular sizes and products stocked.

Once the products are ready for sale, you'll be able to jump on that purchase. Hope this helps! Best, Merrielle Ejis Customer Support
I used to wear Thompson Tees but the cotton isn't the softest and the Ejis shirts just smell better wash after wash.
Hi Staas, Thank you for leaving a review. We are so happy to hear your Ejis undershirt is the best! Best, Merrielle Ejis Customer Support
I used to wear Thompson Tees but the cotton becomes stiff and doesn't wick away moisture like these Ejis shirts do. I really how thin they are and don't show through my dress shirts at work.

I’ve been using these shirts for years. I no longer feel ashamed or embarrassed for sweat stains. I no longer have to worry if I’ll sweat through my shirts. These do take a little getting used to at first. I highly recommend giving a good month before deciding on whether you like them or not. These are pricey for undershirts. I probably spend around 1,000 a year to change them out since I wear them on a daily basis. I recommend waiting for sales if you plan on wearing them daily. Also, I prefer the micro modal material and not cotton. I’d try both to see which you prefer.
Hi Joseph, Thank you for leaving a review and continued support of Ejis. I am so happy to hear that your undershirts have helped you escape embarrassing sweat stains and be worry free! Best, Merrielle Ejis Customer Support
These are now my go to undershirts. It is comforting to sit in meetings without worrying about underarm wetness. I've moved from the v-neck to the deep -v so I can wear them with more than just my work shirts.
Hi Steven, Thank you for leaving a review. We are so happy you love your new Ejis deep v sweat proof undershirts! Best, Gigi Ejis Customer Support

Hi Joseph, Thank you for your review. We're so happy that our micro modal sweat proof undershirts fit you so well and that they keep sweat marks and odor at bay. Best, Gigi Customer Support
Hi Brandon, Thank you for sharing your experience. We're so glad you are happy with the performance of your Ejis undershirts. Best, Gigi Ejis Customer Support
I bought this shirt for use under body armor and it has not disappointed me. I needed a shirt that did not show with the top buttons opened. Of course, I bought the shirt so that I didn’t have arm pit swear stains show as well. The shirt is great at both. I also like that the shirt has a longer length. For sizing, I just measured my chest and ordered appropriately. The shirt fits great and I don’t even notice I am wearing it. If you prefer a bit more loose shirt, then maybe go up a size. Care instructions are simple and straight forward. Flip inside out, wash, and dry. I have had no issues with them. I am interested to try the cotton version as well. I was on the fence about these shirts for a few weeks, but decided to give them a try. I wasn’t disappointed. Read the return policy and you will see that you don’t have anything to lose.
