Great boxer briefs it’s perfect and comfortable! At first hesitation because of the price but was with the purchase. Looking forward to next purchase from Rounderbum Canada eh

I bought these to surprise my boyfriend. They fit really well. As far as the material; I have felt softer fabric, but it's not bad.
