Size Guide

Size Guide

Use centimetre measurements as your source of truth for the best fit.

Our charts show Letter sizes (XXS–XXXXL) alongside cm measurements for chest, waist, inseam and foot length. Always choose by your cm measurements first.

• Between sizes? Choose the next size up, especially if you plan to layer.

• Pants / shorts: check the inside leg to confirm length.

• Footwear: measure standing, heel to longest toe, and match the cm.

• Jackets: allow 2 - 4 cm ease at chest if wearing a mid-layer.

Note: if a brand fits unusually small/large, we’ll add a fit note on the product page. When in doubt, follow the cm values below.
