Waist band and band around thighs are 4/5 because theyre almost nonexistent. That's the kind of underwear/shorts I feel most comfortable in. The shorts are pretty breathable and the only thing I disliked was how short it was, but thats on me. True to size. It wasnt a loose fit but it wasnt super tight.

perfect

I chose a size Large, which I normally wear in women's underwear. I am 5'4" and 158 lbs. The fit was perfect. They stayed put and didn't ride up. The material is soft. Machine wash and dry well. No complaints to speak of.

Poor quality, easily rips at seams.

Size: Medium, Color: Organic Cotton 5 Black Pack

Fit is great but these things do not hold up. I have some Gap hipsters that are older and they are much higher quality. These rip and tear way too easily.
