Reviews

Gift for my boyfriend

"I purchased this item as a Christmas gift for my boyfriend. While the quality of the item itself is fine, I was disappointed with the condition of the box it came in. As shown in the attached photos, the box was dirty and appeared to have been previously opened, as it was sealed with worn and untidy tape. This made me wonder whether the item had been returned or opened before. Because it was intended as a gift, I did not feel comfortable giving it in that condition, so I ended up wrapping it myself. I would appreciate it if this issue could be improved in the future, especially for items purchased as gifts."

"A little bigger than expected from sizing recommendations"

Tyler (4/5)

As close to perfect as it gets

"These right here are the best underwear I have yet to own. I’ve tried a few brands/styles. I ordered a size down by accident and I’m glad that I did. Idk why some say they run small. They are super stretchy. Please never stop making these."

Guillermo (5/5)

Super soft and super comfortable.

"Super soft and super comfortable. No adjusting needed. The only thing I'd change is the rise. . . the waste band rides way too high. I have to roll it down."
