Factor 1 Plus Womens Base Layer Stretch Leggings

Factor 1 Plus Womens Base Layer Stretch Leggings contour to your bodies shape to provide a snug comfortable fit with extra support.

Manufactured from super soft 95% polyamide yarn with 5% Elastane for added stretch, these close fitting base layer leggings utilise body mapping technology to construct innovative seamless body forms, enabling features such as perspiration control mesh zones to be knitted around the groin and along the calfs. 

Theses leggings are seam free on the outer edge, requiring just one flat seam to seal the inner legs and gusset, whilst the ends are finished with a flat ankle seam to reduce the pressure exerted from walking shoes and ski boots. The finished height of the waist is generous to help prevent lower back exposure during activities, and the low profile waist band itself is constructed from polayamide and elastane to give a lot of stretch and support without cutting in to your waistline.

These Sub Zero leggings are one of the best lightweight thermal underwear ranges for general outdoor use. The simple design makes them compatible with most sports where you need to keep warm and dry. They cross over in to anything from skiing  through to hiking and camping, and can be used in combination with the Sub Zero Factor 2 thermal mid layer range for extra warmth in extreme conditions.

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 womens Factor 1 Plus base layer leggings. There is a tolerance of +/- 5mm.
