These are the BEST ever briefs I’ve purchased. I love these! Quality, fit, price and comfort is far beyond the other name brands like Jockey, Hanes, Fruit of the Loom etc to name a few. Those only last a few months (quality) before ripping or elasticity fails or groin area wears out from stretch. But NOT the Wirarpa men’s cotton stretch underwear support briefs. It is made with our anatomy in mind with perfect support. I only buy these now and will never buy another brand.
