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. If you have a base layer that fits correctly, then use it as a template for these measurements.
HOW TO MEASURE
Chest - Measure the full circumference of your chest just below the armpits
Hem - Measure the full circumference at the top of your hips
Back Drop - Measure from the back of your neck to the base of your spine
Arm Length* - Measure from the end of your shoulder to your wrist
* This measurement is only applicable for long sleeves. Short sleeve versions of these mid layer tops finish just above the elbow.
MID LAYER FIT
Our mid layers will contour to most body shapes when worn thanks to the fabrics in-built stretch. You should wear them close fitting but not so they are restrictive. Wearing baggy or ill fitting mid layers will lead to the loss of heat and a reduction in their wicking properties.
These mid layers are designed to be worn over the top of our base layers but they can be worn directly next to the skin if required. Sizes for both Sub Zero base layers and mid layers are comparable - so if you wear a Factor 1 plus base layer in large, then you should require a Sub Zero Factor 2 mid layer in the same size and vice versa. However, this may not work out for everybody so please consult the size chart below.
Please be aware that these measurements are taken from the garments unstretched, apart from the 'TO FIT CHEST' column, that indicates the range of fit. They are applicable to our long sleeve mid layers in round neck and zip turtle styles, short sleeve round neck style, and sleeveless style top as the bodies are based on the same pattern.
This is also the case for the Factor 2 Plus range - it is a thicker fabric but the construction utilises the same patterns as the Factor 2 mid layer range, hence the sizing is the same.
The table below shows the garment measurements for our Factor 2 Mid layers. There is a tolerance of +/- 5mm.
The table below shows the actual garment weights per size for each of the different styles of Factor 2 mid layer tops we manufacture. There is a tolerance of +/- 20g. R/N refers to round neck.
