What Does GSM Mean?

GSM stands for Grams per Square Meter. It measures the weight of a fabric.

In simple terms:

• Low GSM = Lightweight fabric
• High GSM = Heavier, thicker fabric

Think of GSM as a quick indicator of how thick or dense a fabric feels.

Why GSM Matters for Kids' Clothing

1. Comfort

Lightweight fabrics (low GSM) feel softer and more breathable, which is ideal for everyday wear.

2. Weather Suitability

• Low GSM (120–160): Perfect for hot and humid climates
• Medium GSM (160–220): Great for all-season wear
• High GSM (220+): Best for cooler weather or layering

3. Durability

Higher GSM fabrics tend to be more durable and long-lasting, which is helpful for active kids.
