Cure to White Deodorant stains!
Wow! Such quality! Bright White and the collar is perfect. Love that those awful White stains from deodorant won't be haunting my husband's work shirts anymore.

Nice shirts, but have a bit of a chemical smell…
My hubs says these are true to size, comfortable, and would recommend. But, they have a slight chemical smell to them that still isn’t gone after a couple watches. So, that’s why only 4 stars. We are sensitive to smells though, so it might not even be noticeable to some.

Very Comfortable
The softness is so good. It doesn’t feel tight or stick to your skin if you perspire.
