200 GSM vs 300 GSM — what's the difference?

This is a genuinely useful comparison to make before buying anything by weight alone, because GSM without fiber content is an incomplete fact — 300 GSM cotton terry and 300 GSM polyester fleece behave very differently even at the same density. We don’t sell a fabric at exactly 200 or exactly 300 GSM, so we won’t pretend to compare two of our own pieces here. What we can say honestly: our heaviest cloth, at 340 GSM (The Soft Layer, The Easy Trouser), sits just above the “300” end of this comparison — cotton terry, dense enough that the weight is the first thing you notice putting it on. Our mid-weight pieces, at 270–282 GSM (The Everyday Tee, The Weekend Trouser, The Quiet Sweatshirt), sit close to the “300” range too, just under it. If you’re shopping by this comparison and want to feel where our own pieces land on it, the ladder below places all four of our lab-verified weights against each other.
