This red, blue, and white striped t-shirt is perfect for summer months! The fabric is soft. Though it's lightweight enough to be comfortable in warm weather, it doesn't feel flimsy. It is fully opaque. The neck is in excellent shape-not at all stretched or "baconed." The ribbed collar gives it a classic look. I love it but it's a bit small for me and I don't wear it anymore. I'd say it fits a bit snug for a medium. For reference, I am 5'8", 165 lbs with a 40" chest. Chest of the shirt is 20", and length is 26". Measurements are approximate. From a smoke and pet-free home. The garment has always been laundered on cold with scent-free detergent and hung up to dry. Please get in touch with any questions and I will respond as soon as I can!
