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.
It doesn't matter if you are 25 or 65 years old we all need the most comfortable underwear. Knobby tick the boxes for comfort ball room coolness. The stretch fabric allows movement no chaffing or sweating. Best ever!
Step into a world of amazing underneaths that are ridiculously good and sustainably comfy
