Everything I've purchased has been for my son. The building he works in is very hot in the morning because he starts 2 hours before the A/C comes on, and these undergarments have made him so much more comfortable. He likes to maintain a more professional appearance and Ejis products help tremendously!

Peace of mind
What a relief to be wearing something that removes the worry of under arm sweat patches. It’s been incredibly hot but it’s been fine underneath a shirt. It is better wearing th t shirt as an undergarment as the double layer under the arms is quite obvious and make sure you buy two so you have a spare for the next day!

4th Order!
Been buying these shirts for years and absolutely love them. I have both fabrics and still cannot decide which one I like best. 10/10, at least!
