“These undies are wonderful. I go back and forth between loving the boyshort mico fabric or 4.5” cotton ones more. I didn’t like the boy shorts in cotton because they were tight in the wrong places, but that might just be how my legs are. So, the micro fabric seems to have a bit more stench. So if you’re trying to decide between two sizes because one size might be too big on you, but you don’t like a tight fit, I would consider getting the micro over cotton. Also, customer service is awesome!! One thing that would be awesome is a higher waist option for the boy shorts. A mid-rise boyshort, the way that the 4.5 trunks are mid-rise would be amazing!”
