Hoodie size guide: fit, fabric and what 350 GSM means
A hoodie only looks right when the size is right. This guide explains how our hoodies fit, how to measure, and what "350 GSM" on the label actually means.
What does GSM mean?
GSM stands for grams per square metre: how much one square metre of the fabric weighs. The higher the number, the thicker and heavier the fabric. 350 GSM is considered heavyweight: the hoodie feels solid, keeps its shape and keeps you warm on cold evenings.

Lay a hoodie that fits you well flat on a table and measure:
- A. Half chest: from armpit to armpit
- B. Length: from the highest point of the shoulder to the hem
- C. Sleeve: from the shoulder seam to the end of the cuff
Compare your numbers with the size chart on each product page. It shows the measurements in cm (or inches), with a photo of where we measure.
