Direct answer: A midweight hoodie around 350–450 GSM is a versatile starting point for streetwear; heavier fabric can create a premium drape, but it also raises heat, shipping weight, and shrinkage risk.
Hoodie weight is useful only when read alongside fiber content, knit construction, fit, and wash behavior. GSM is a comparison tool, not a quality guarantee.
Search intent: Buyers searching for “what gsm hoodie for streetwear heavyweight hoodie” usually want a shortlist, trade-offs, and a way to avoid an expensive mismatch.
