Versatility is key with our Fruit of the Loom cotton stretch collection. Not only are they great for everyday wear, but they are ideal for someone who leads more of an active lifestyle. These men's underwear have super soft ring spun fabric with stretch for all day movement, so you remain comfortable throughout the day. The CoolZone fly was designed for increased ventilation and extra stretch with spandex. We are proud of the hard work we put into the fit of each product, which is why we back every purchase with our Best Fit Guarantee.
