Boxerbriefboy – I’m not sure if these underwear are the Kirkland brand from Costco, but they look just like them. If you have a Costco nearby or can order any from their website, do it! The material is super soft and they fit perfectly, size wise, so for instance if you wear a medium, feel safe ordering a medium. You’ll love them! I know we bought some and have since went back and bought more for all of us, oh and they are not expensive ($12.99)and you get 4 per pack and they come in a mixture of black, dark grey and dark blue and there is no lettering on the waistband. Let me know what you think if you get some. You won’t be disappointed! 😏
