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.

Elastic band is not great
Size: X-Large, Color: Organic Cotton 5 Black Pack
The cotton material is comfortable and seems like it will last some time because it isn't thin like most. However, I could really use a thicker, more durable elastic band.

Comfortable
Size: Large, Color: Organic Cotton 5 Black Pack
Comfortable and decent looking black underwear in a hipster, boy cut style. Material is soft and lightweight, kind of thin, but since they’re black they’re not see through at all. The elastic band at waist is also thin and not too tight so it’s very comfortable and doesn’t dig in at all. Five identical pairs in the order makes this a decent value, especially at this price and for Organic cotton material. The large size was perfect for me I sized up based on the recommendations). I’m pretty happy with this order.

Comfortable, great coverage, perfect fit!
Size: Medium, Color: Organic Cotton 5 Black Pack
These boy shorts are the perfect cut and extremely comfortable! They were true to size, great coverage and they fit me great. They stay in place and don't ride up in my pants so that was a huge plus too. Really glad these came in a pack of multiples cause I would definitely want more. I actually might order more anyways cause I like them so much, haha! Definitely recommend these, they are a great price for comfortable, nice quality underwear.
