160, 180 or 240? What the number on the label tells you about how a tee will feel, drape and last.
GSM stands for grams per square metre. It is simply how much a square metre of the fabric weighs.
Around 160 GSM is light and airy, good for layering and hot days. 180 GSM is the everyday middle: opaque, soft and easy to wear.
At 240 GSM a tee becomes structured. It hangs away from the body, hides what is under it and feels substantial in the hand.
Heavier is not automatically better. Pick the weight for how you want the tee to sit.
