The fabric

GSM is grams per square metre, so 180 is the weight of the knit. Under 150 is a summer tee that shows what is under it. Over 220 starts behaving like a sweatshirt. At 180 the fabric holds a shape at the shoulder and still moves in Cairo in June.

Ne 40s is the yarn count. A higher number is a finer yarn, which is why a 40s knit takes a sharper print edge than the 20s and 30s yarns most of the local shelf runs.

Extra-long staple means the individual cotton fibres are longer, so fewer fibre ends stick out of the surface. That is the reason the shoulder does not pill after a wash, and it is the only reason worth paying for the word Giza.

Water-based discharge print, 280 by 350 mm at the chest. Discharge removes the dye rather than sitting on top of it, so the print has the hand of the fabric instead of the hand of plastic. It cracks less because there is less to crack.

Four sizes, measured flat in centimetres, from 58 to 66 cm across the chest. TOLERANCE ± 1 CM — stated here rather than buried, because a stated tolerance prevents the return and a hidden one causes it.

The finish. The plan is a silicone wash for a dry hand, but the fabric is not booked, so that sentence carries the word pending on every product page until it is. We would rather say pending than say something confident and revise it after you have paid.
