| 160-200 GSM | Midweight | Standard casual wear, corporate uniforms | Good balance of comfort and durability | Moderate cost |
| 200-240 GSM | Heavyweight | Streetwear, premium casual, boxy fits | Structured, quality feel | Higher cost |
| 240-300 GSM | Extra Heavyweight | Luxury streetwear, statement pieces | Very structured, armor-like feel | Premium cost |
| 300+ GSM | Ultra Heavyweight | Niche fashion, limited editions | Too stiff for daily wear per buyer feedback | Highest cost |
