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.

Quality control

Size: Large, Color: Black-4 Pack, Size: Large, Color: Black-4 Pack

They did fit well but now the waist band is coming off on all of them. Quality control needs to look into this problem. I would have bought them again if they solve this problem.

Great!

Size: Medium, Color: Multicolored19-4 Pack

I have ordered three packages of these over the years. They are solidly made and withstand washing and drying without the color fading and elastic band stretching. They are sized correctly and are super comfortable.
