Soft and sturdy cotton Our Kids Line is unisex and offers the same modern, boxy fit as our adult t-shirts—they’ll make your future cowboys and cowgirls look sharper than a brand-new pair of spurs! Sizing: Our kids longsleeve shirts come in 3 sizes: Medium (age 4-7); Lage (age 8-10); and XL (age 9-12). For children 12+ years old, we recommend they transition to our Adult size Small shirts. Diamond Cross Guarantee: We want you to love any DCR gear you own. If you aren't happy with the fit or quality of an item, return it within 30 days for a different size or refund.
