What’s my size?

We feel that the best method to determine your size is to measure a similar favorite garment you already own – i.e. an insulated ski jacket if you are buying an insulated ski jacket etc. Compare with the chart below which is unique for each product. Please bear in mind that our shell garments are made to be quite loose fitting, to be able to add one or more layers beneath.
