Stay with the flex

Michael D.

The two pairs of flex are quite possibly the best underwear I’ve ever worn. Not as happy with the two pair of all day underwear. Wish I just bought four pairs of the flex. But oh well live and learn. Only 50 dollars down the drain. By the way the drop cut shirts are simply awesome! Great company making well made clothing. I have every color shirt plus some duplicates to wear just to the gym.

Functional and comfortable

I am very impressed with the quality of these underwear, they fit comfortably and are breath. They do not bunch up or cause chafing. Great product, I love them!
