SIZING GUIDE
There are no standard sizes for clothing, which is why each brand has their own unique cut and fit. Please do not presume you are the same size between brands for a similar product.  

HOW TO MEASURE
Chest - Measure the full circumference of your chest just below the armpits
Front Drop - Measure from beneath your Adams Apple to below your waist
Back Drop - Measure from the back of your neck to the base of your spine
Arm Length* - Measure from the side your neck to your wrist

LIGHTWEIGHT WINDPROOF JACKET & SMOCK FIT
These garments are cut generously so they can easily be placed quickly over bulky outer clothing for instant relief from penetrating wind in cold conditions. In warm temperatures, the baggy fit allows for greater internal air circulation to cool you down and manage perspiration levels. 

Please be aware that these measurements are taken from the garments themselves, not showing recommended sizes. The chest measurement seems large for each size, but this is to accommodate other garments worn underneath. The sleeve is constructed without a shoulder seam so the measurement is taken from the side of the neck. The large contoured drop back is shown in the difference between the front and back measurements. Both the jacket and the smock utilise the same pattern.

The table below shows the garment measurements. There is a tolerance of +/- 5mm.
