GSM — grams per square metre — is the weight of a fabric. Higher GSM usually means a thicker, more opaque and more durable garment. But heavier isn't always better, especially in Mumbai's climate. Here's how to choose.
T-shirts: 160–220 GSM
- 180 GSM regular cotton — budget-friendly for events, marathons and giveaways.
- 180 GSM bio-washed cotton — the all-rounder for fests, company tees and everyday merch; our top-rated tee.
- 240 GSM oversized — heavier, drop-shoulder fit; the streetwear standard for brand drops.
Polos: 220–260 GSM
- 220 GSM cotton — light, breathable daily uniform polo.
- RS Signature 230 or 260 GSM — premium combed ring-spun cotton pique, same finish in two weights: 230 for uniforms and clubs, 260 for leadership, client-facing teams and gifting.
Hoodies: 280–400 GSM
- 280 GSM hoodies — light fleece, comfortable year-round in Mumbai and in air-conditioned offices.
- 400 GSM heavyweight — thick, one-side brushed fleece for winter, travel and premium merch.
Bio-washed vs non bio-washed cotton
Bio-washing is an enzyme treatment that removes loose surface fibres. Bio-washed garments are softer, pill less and shrink less. Non bio-washed cotton is slightly crisper and more economical. For merch people will wear repeatedly, bio-washed is worth the small premium.
