350 GSM vs 450 GSM vs 500 GSM: The Ultimate Fabric Weight Guide for Custom Streetwear Hoodies
Discover how fabric weight determines hoodie drape, structure, durability, and retail pricing. An insider comparison between 350 GSM, 450 GSM French terry, and 500 GSM heavyweight brushed fleece from a direct Sialkot manufacturer.
For emerging streetwear brand founders and apparel merchandisers, no single technical specification impacts customer satisfaction and perceived luxury more than **GSM (Grams per Square Meter)**. In modern drop-culture, lightweight 240–280 GSM promotional blanks are quickly recognized as cheap, while substantial 400+ GSM heavyweight fabrics command premium retail prices between $95 and $180 per piece.
Understanding GSM: What Does Grams Per Square Meter Actually Mean?
GSM measures the metric weight of one square meter of milled fabric. Higher GSM indicates a denser weave, thicker yarn count (such as 16s or 20s ring-spun combed cotton), or a tight double-knit construction. At Glory Zone, we operate dedicated circular knitting machines capable of custom yarn compositions, from 100% long-staple organic cotton to 80/20 cotton-poly blends for enhanced anti-shrinkage.

Loopback French Terry vs. Brushed Fleece: Which Structure to Choose?
**French Terry (Loopback):** Characterized by soft unbrushed loops on the inside and a smooth jersey face on the outside. It absorbs moisture effectively, breathes well, and offers a crisp, tailored architectural drape that streetwear labels favor for year-round collections.
**Brushed Back Fleece:** The internal cotton loops are mechanically brushed through napping machines, creating a fluffy, plush fleece surface that traps air for maximum thermal insulation. Ideal for colder climates and winter collections.
