Nike T-Shirt - Black - Size 4

The t-shirt is made from polyester.

While durable for everyday wear and light activity, its polyester composition might not offer the same moisture-wicking or breathability as specialized performance athletic wear for intense sports.

A regular fit provides a standard cut that is not too tight or too loose, offering a comfortable silhouette for most body types and activities.

It can be worn in hot weather, but polyester is less breathable than natural fibers like cotton. For very high temperatures and strenuous activity, consider lighter, more breathable materials if available.

This specific product is a black t-shirt in size 4. Other sizes and potentially colors may be available under different listings for the Nike Kids' T-Shirt line.

Machine wash cold with like colors, use mild detergent, do not bleach, and tumble dry low or hang dry. Iron on a cool setting if needed.

Ensure you followed the care instructions precisely. Avoid high heat drying. If shrinkage occurred, you might try stretching the fabric gently while damp.

Check that you are washing with like colors and using a mild detergent. Avoid prolonged exposure to direct sunlight when drying. Wash inside out to protect the fabric's color.

This can sometimes happen with polyester. A fabric softener might help, or ensure you are not using excessive detergent. Re-washing with a small amount of vinegar in the rinse cycle can also help soften the fabric.
