Size guide

Sizing guides for the TREK MKII jacket:

Some of our customers seem committed to squeezing into a smaller size (or a size which in theory they feel should just about fit); often seemingly ignoring the sizes we provide? The measurements provided below are accurate garment measurements; please be realistic. Our jackets are substantial and functional field jackets (coats), with a considered contemporary fit, which you will want to wear under garments with, and are not snug summer dress jackets. If in any doubt we recommend you go for the larger option. We have often exchanged garments for larger sizes, but never made an exchange for a smaller size. Thank you.
