Mens Factor 1 Plus Base Layer Size Chart
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. 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
Waist - 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 the base layer tops finish just above the elbow.
BASE LAYER FIT
Our base layers have a lot of stretch, so they will contour to most body shapes when worn. You should wear them close fitting but not so they are restrictive. Wearing baggy or ill fitting base layers will lead to the loss of heat and a reduction in their wicking properties.
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. The back-drop is the critical measurement. This ensures the body length is correct to prevent lower back exposure. Even if the chest measurement looks too small, the stretch of the fabric will enable a good fit.
The table below shows the garment measurements for our Factor 1 Plus base layers. There is a tolerance of +/- 5mm.
