Sizing: European sizes — go one size up. EU sizes run smaller than US sizes, and this light 150 g/m² (4.4 oz) organic cotton is softer than a standard tee and can shrink slightly in the first washes. Between two sizes? Take the larger one. The full size chart in cm and inches is below and among the product photos.

How to choose / Come scegliere: take a T-shirt you already own and like, lay it flat and measure it. Compare with the table below.
Prendi una maglietta che hai già e che ti sta bene, stendila sul tavolo e misurala. Confronta con la tabella.

Our advice: go one size up. This is a light 150 g/m² (4.4 oz/yd²) organic cotton — softer than a standard tee — and like all light cotton it can shrink slightly in the first washes. If you like a relaxed fit, or you're between two sizes, take the larger one.
Il nostro consiglio: prendi una taglia in più. È un cotone organico leggero da 150 g/m², più morbido di una maglietta classica, e come tutti i cotoni leggeri può stringersi leggermente ai primi lavaggi. Se ti piace comoda, o sei tra due taglie, prendi la più grande.
