The Firth - Size Guide
How to Find Your Perfect Fit
Grab a soft tape measure and compare your measurements with our size guide below.
These jumpers are unisex sized. Chest width is measured with the jumper laid flat, from armpit to armpit. Body length is measured from the centre back of the neck to the hem, and sleeve length from the centre back of the neck to the end of the cuff.
Please note: All measurements are approximate, due to the natural give of wool and the seamless knit construction.
