When sourcing hoodies, the fabric weight (GSM - Grams per Square Meter) is the primary indicator of quality; for premium streetwear, aim for 300-400 GSM, while promotional items typically range from 200-250 GSM. Ensure the material blend matches your needs, such as 100% Cotton for breathability and high-end feel, or CVC (Chief Value Cotton) blends (e.g., 60/40 cotton-polyester) for better shrink resistance and durability. Always verify the fleece type, choosing between brushed fleece for warmth or French Terry for a lighter, moisture-wicking professional finish.
