We’re glad to hear that you found the material light and suitable for warm weather, though we’re sorry to learn that the design didn’t fully meet your expectations. The Next Level™ Unisex Tri-Blend 3/4 Sleeve Baseball Raglan Tee does feature a curved bottom hem rather than a traditional straight hem, which may contribute to the rolling you’ve experienced. This design detail is reflected in the product’s sample images to help customers make well-informed choices. We truly value your input, and we’ll be sure to pass along your comments as we continue working to improve both our product presentation and selection.
