Factor 1 Plus Mens Base Layer Leggings

Factor 1 Plus Mens Base Layer Leggings offer lightweight leg protection from the cold whilst actively managing perspiration.

 

Manufactured from super soft polyamide yarn, these thermal leggings have been designed using body mapping technology to provide performance enhancing features without the need for seams. Ribbed zones on the outer leg and on the knees provide extra support and insulation, whilst mesh zones around the crotch and lower back aide dispersal of perspiration. 

To prevent rubbing points during high activity we have constructed these leggings so only one seam is needed, and this runs along the inside legs and gusset using strong but low profile flat locker stitching.  We also finish the ends of the legs with a flat single skin cuff to help reduce 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 waistband itself is constructed from polyamide and elastane to provide stretch and support without cutting in to your waistline.

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

Washing instructions for Sub Zero base layers are printed on a white silk tag stitched to the back neck and can also be found knitted in to the waist band. Please follow these instructions carefully as failure to comply with them will make your guarantee void. If you have removed the tag or are unsure of the washing symbol meaning, the full washing instructions can be found below.

  • Machine wash or hand wash in water not exceeding 40°C or 105°F
  • You can use a mild washing detergent but ideally you want to use a base layer specific washing treatment 
  • Wash dark colours separately, do not bleach, do not use fabric conditioners
  • These base layers can be spun dry in a washing machine
  • Do not tumble dry. These base layers will quickly dry on a line or airer as they retain very little water once spun/rung out. 
  • Do not dry clean
  • Regular ironing may be performed at a low setting (110°C, 230°F) only, but we advise against it.

 

GENERAL WASHING TIPS
When you go to wash any garment with a zip, ensure it is done up fully otherwise the exposed teeth may cause harm in the wash cycle. The same can be said for garments containing Velcro. Your best course of action would be to wash these garments either by hand or on their own in a washing machine.

With the advancement in detergent technology, you very rarely need to wash any garments these days above 30°C. It is better to use a specific anti-bacterial wash-in treatment rather than increasing the temperature.

A lot of Sub zero products, especially the base layers and mid layers, can be ironed on a low temperature setting. We would advise against this as the heat settings on irons are not always reliable. In any case, the stretch properties of synthetics helps reduce creases in the wash and if there are any afterwards, they often drop out when worn.

Like most synthetics, Sub Zero fabrics will melt or burn if exposed to flame or direct heat. They are not flame resistant; do not use them near ANY direct source of heat or flame. This includes some of our merino wool products that contain a small percentage of synthetic yarn.
