    Less Expensive Solution to Sweat Problem!

    I had previously purchased these shirts for my son, in the interim, who was planning to have surgery to remove his sweat glands. The shirts worked so well that he has decided not to have the surgery, in the hopes that he will outgrow the problem as his grandpa did. I purchased three more so that he could rotate them daily. Very pleased with these shirts and highly recommend!

    Quality product - problem with shipping

    My son and I have a horrible issue with sweating. As teachers, you need to feel confident in the classroom. We have been purchasing another brand of shirts for 5 years behfore coming across Ejis. We decided to give them a try during a promotional offer. The order took 2 weeks to arrive in Canada, and unfortunately, our order was sent incorrectly. We ordered V-Neck and received Crew Neck instead, We needed them immediately for a function, so we were not able to return them. The quality of the shirt is quite good. The absorbent pads are definitely thinner than other brands on the market, and the odour protection works. The Crew neck collar is not stitched as well as a regular white undershirt, so you may not want to have much of the collar visible when wearing them. That being said, you would have no problem wearing a crew neck under a dress shirt, because there is not much to the finished edge. For sizing, they fit a little small. I am normally a Large, but this felt tight when I started the day. I have to admit that it was not uncomfortable during the day, so I never gave it a second thought after first putting it on.. The shirts work, and the price is not an issue when you consider the confidence you regain.

    Persistence

    After some original shipping issues, the company was kind enough to send replacements and allow me to keep the old improper shipment. Although I did not end up exactly with what I had ordered and it took several rounds of communication, I am impressed and now a lifetime loyal customer for their honorable efforts to make things right.

    Product was quite good

    Just used the other night. Son is a member of a RifleSquad and sweats profusely. No underarm sweat when performing this time but still sweat marks down his back. You need to put this material down the back of this undershirt also otherwise a good product. Need to order another in a larger size because they seem to run small. Thank you.

    V neck shirts

    Definitely worth having. Wore them underneath playing golf. No more sweat stains even when it’s scorching hot.

    These shirts are phenomenal. I normally sweat through the underarms of my shirt in no time, but with these not even a trace of sweat all day long.

    Under shirt.

    Good. But the size I ordered (2x) runs a little small for me. I will order 3x next time.

    Life Changing

    Truly a life changing product. My anxiety around sweating has gone down drastically, I can wear clothes I never would have worn before, and my confidence is boosted. I have been wearing the cotton v-neck shirts for a couple years and recommend buying a size smaller than usual because the extra layers around the armpit add bulk that isn’t as noticeable if you choose a snug fit. I want to buy more shirts with the added length to stay tucked. Wear a “black and white” anti-stain antiperspirant as with any white shirt, they will yellow over time and as of yet, I haven’t found a way to get rid of the stain. Perhaps because the interior layer is micro modal? I’m not sure. When will the L cotton V be back in stock???

    Good but …

    The shirts do the job by stopping sweaty underarm marks- but as they are regularly washed they have lost their ‘whiteness’ and have become yucky grey. So not major but annoying for an expensive garment

    Awesome

    Well worth the price! I would never spend that amount for undershirts but after ruining too many shirts and being uncomfortable, I took a risk. It was well worth it. I recommend it.

    Pretty good

    These shirts are pretty good. They last about a year before the seams around the underarm start weakening/splitting. (With regular washing in accordance with the Ejis-provided instructions, of course.) The marketing tag sewn to the bottom of the shirt also creates holes over time as the regular washing in the places where the tag's stitches are located. Overall the shirts work well.
