Garment dimensions when measured laid flat.

Fitting Advice - The fit is intended to be regular, but as the fabric is quite stretchy if you prefer a slim fit, you can safely size down compared to our size guide chest sizes.

We advise you to compare these flat measurements to a comparable garment (do not compare a jacket to a base layer for example) that you already own and like the fit of to help you work out which size to order from us. However, please remember this is a guide only - 2 garments with same flat dimensions but made of fabrics of different stretch will fit you very differently. If you'd rather buy 2 sizes and send the one back that doesn't fit, this is fine by us!
