North Sea clothing offers an extensive range of sizes providing you with the most comfortable fit. Our sizing is your chest size in inches. If you are unsure of your N.S.C size, take a measurement around your chest at your underarm in inches with a soft tape measure. Our clothing fits true to size, if you prefer a loose fit, we suggest you order a size up. Refer to the size guides below for further measurements.
Knitwear sizing is equal to the chest measurement of the garment, underarm to underarm x2 in inches.
Outerwear is sized to allow room for ease of wear. We recommend ordering the size labelled as your chest size.
We recommend comparing the measurements below to a pair of well fitting trousers you already own to ensure you order the best fit.
Our Marine Type 2 shoe is a standard to wide fit.
The chest measurement is taken from armpit to armpit on a flat surface. Length is taken from highest shoulder point to hem and sleeve is from highest shoulder point to cuff.
