Best Heavyweight Hoodies in the UK (2026): GSM, Fit & What to Look For
Heavyweight hoodies have become a major part of modern streetwear, but the largest GSM number is not automatically the best choice.
What makes a hoodie heavyweight?
GSM means grams per square metre and describes fabric weight. Around 400 GSM and above can create substantial structure, while 500 GSM moves into ultra-heavyweight territory.
What should UK buyers look for?
Consider GSM alongside composition, silhouette, measurements, finishing and how you plan to layer the hoodie through changing UK weather.
