Our Men's Classic White a-shirts are comfortable and versatile. They are made with super-soft, 100% cotton ribbed fabric, providing a cool and comfortable fit that forms to your shape. These a-shirts have generous length that stay tucked in all day and keep you comfortable in every situation. Fruit of the Loom's flex hem won't unravel keeping these a-shirts durable wash after wash. They are sleeveless, so they may be used easily as undershirts or worn on their own. Machine wash them cold. They are comfortable and light enough to be worn as an extra layer without adding extra warmth to an outfit. Each pack has six shirts and comes in S, M, L and XL.
