Bought the monthly subscription for my partner. He was super happy and excited to get new ones every month. He wouldn't normally go for pattern briefs but loved the designs. True to size, good fit and super comfy!
100% best underwear for men. Changed over from (another brand) and I am not going back. Softer material, better fit and awesome designs.
