"Undershirt" defined
I ordered one each of the three options a couple months ago as a trial. My drawer now contains 2 crews, 13 white V-necks, and 1 beige. The fit is perfect - snug to the body without any hint of compression (the close-fitting sleeves are especially nice), and the material is so soft and lightweight that it often feels like I don't have one on. Even under a polo top they feel like a "second skin". And the deep V and shorter sleeves truly keep them invisible. My only quibble, and it is a personal one, has to do with color. I have found that my white shirts, both dress and polo, demand a white undershirt - anything else makes them look dingy. Laundering and care are a breeze. Since I am a newcomer to Underfit, I will leave the issue of durability to others, but I understand that they have a very long life. In short, "undershirt defined". Behind this wonderful product is a website that is very user-friendly, and service and delivery that are absolutely top-rate (my longest wait for an order was 3 days). Bravo Leigh and Underfit!
