The best heavyweight hoodie is not simply the one with the highest GSM. Fabric weight, construction, fit and finish all determine how it hangs, feels and lasts. This guide compares KHAIR’s current 420–500 GSM hoodies so you can choose the right structure and silhouette.
What makes a heavyweight hoodie worth buying?
GSM means grams per square metre and describes the weight of the fabric. A 420 GSM hoodie already feels substantially heavier and more structured than a typical lightweight sweatshirt. At 500 GSM, the fabric has an even denser hand and stronger drape. GSM does not measure quality by itself, so also look for stable ribbing, a well-constructed hood, pre-shrinking and a fit that works with the fabric.
KHAIR’s hoodies are designed around a relaxed streetwear silhouette. Dropped shoulders and a roomier body allow the heavyweight fabric to fall cleanly rather than cling. Use the garment measurements in the hoodie size guide and compare them with a hoodie you already own.

Choose 500 GSM for maximum structure
The Washed Black Hoodie and Los Angeles Patchwork Zip Up use 500 GSM cotton fleece. They are the strongest choices when you want a substantial layer, a structured hood and a silhouette that holds its shape.
Choose 420 GSM for heavyweight comfort with easier layering
The Athletics Vintage Red Hoodie uses 420 GSM organic cotton fleece. It still has a premium heavyweight feel, while the specialist vintage wash and collegiate graphics give it a more expressive finish.

Heavyweight hoodie questions
Is 500 GSM too heavy for everyday wear?
It depends on your climate and layering preference. A 500 GSM hoodie is deliberately substantial and works best when you want warmth, structure and an outer-layer feel.
Is 420 GSM considered heavyweight?
Yes. A 420 GSM cotton-fleece hoodie has a noticeably substantial feel while remaining easier to layer than the densest 500 GSM options.
Should I size up for an oversized hoodie?
Not automatically. KHAIR hoodies are already cut oversized, so compare the garment measurements with a hoodie you own and choose the silhouette you prefer.
