Mens Factor 1 Base Layer Leggings 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 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. 

We produce our leggings in two versions, with a fly opening and without a fly opening.  The fly is constructed from a double thickness pouch.  

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

Factor 1 Base Layer Leggings are one of the best lightweight thermal underwear ranges for general outdoor use.

These thermal leggings are manufactured from stretchy tubular 100% polyamide ribbed fabric with a hydrophilic treatment for superior moisture management.

The extra generous waist heights on these leggings help to prevent lower back exposure and give extra thermal protection to your kidneys. The waist itself is constructed with an internal strong rubber elastic core that is seamed over with Factor 1 fabric for a low profile. The double layered fabric gusset provides added thermal protection around the groin, whilst the ends of the legs have flat ankle seams that help to reduce pressure exerted from walking shoes and ski boots.

These base layers cross over in to anything from, skiing, through to hiking and camping, and can be used in combination with Sub Zeros Factor 2 mid layers for extra warmth in extreme conditions.

Please note: These are end of line garments. There may be some slight colour variations where they have been folded, and some may have different versions of our logo, but apart from this these base layers are perfect. We have greatly reduced the price to reflect this. Our Factor 1 Plus legging has superseded this design.
