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 pair of base layer leggings that fits correctly, then use it as a template for these measurements.  

HOW TO MEASURE
Waist - Measure the full circumference of your torso above the hips
Inside Leg - Measure from the top of your groin down the inside of your leg to the ankle bone. 

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 the inside leg measurements are taken from the garments unstretched. The waist measurement indicates the range of fit.  

The table below shows the garment measurements for our Factor 1 Plus base layer leggings. There is a tolerance of +/- 5mm.
