The Weight of a T-shirt: What is Oz Value and Why Does it Matter?

The Identity of a Fabric: What is Oz Value and How Do You Choose the Right T-shirt?

Have you ever considered the weight of a fabric when choosing a t-shirt? This value, expressed as oz (ounces) or g/m² (grams per square meter), tells you everything about a t-shirt's feel, durability, and suitability for the season.

What Does Oz Value Mean? In short, it means the density of the fabric. The higher the number, the thicker and more substantial the fabric.

• Oz Difference in Polyester and Cotton: Since polyester fibers are lighter than cotton, a 100% polyester sports t-shirt can be as light as 3.5 oz. For a 100% cotton t-shirt to offer similar durability, it generally needs to be at least 4.2 oz.

How to Choose the Ideal Oz Value by Season?

• For Summer Months (Light and Airy): Your skin needs to breathe in hot weather. That's why lightweight t-shirts between 4.2 oz and 5.0 oz (140-170 g/m²) are ideal. These shirts are thin, allow for airflow, and keep you cool.
• For Winter Months (Substantial and Protective): In cold weather or when layering, a more substantial feel and better insulation are desired. Heavier t-shirts between 5.3 oz and 6.1 oz (180-205 g/m²) retain body heat better and offer a more durable structure.

Knowing the right oz value ensures you are not just buying a t-shirt, but the most appropriate comfort for the season and your needs.
