Factor 1 Plus Mens Base Layer Undershorts

Factor 1 Plus Mens Base Layer Undershorts are ideal for any sport where perspiration needs to be controlled and heat removed quickly. They are most suited to high aerobic sports such as rowing, running and cycling.

Manufactured from super soft polyamide yarn, these snug fitting undershorts have been designed using body mapping technology to provide performance enhancing features knitted directly in to the fabric. Stretch rib knit around the groin and on the thighs provide extra support, whilst the fine mesh back panel disperses any excess perspiration and heat.

To prevent rubbing points during high activity we have constructed these undershorts with only one seam that neatly runs along the inside gusset using strong but low profile flat locker stitching.

The finished height of the waistband is generous to help prevent lower back exposure during activities, and is itself constructed from polyamide and elastane as part of the garment knit, to provide stretch and support without cutting in to your waistline.

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.
