Washing instructions for Sub Zero Merino Wool Mid Layers are printed on a white silk tag stitched to the back neck of the long sleeve top and the inside waist of the leggings. 

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 30°C or 86°F
  • If using a machine to wash them, then you will need to use a gentle setting. A specific woollen wash programme is ideal. 
  • You can use a mild washing detergent but ideally you want to use a base layer/mid layer specific washing treatment 
  • Wash dark colours separately, do not bleach, do not use fabric conditioners
  • These mid layers can be spun dry in a washing machine, but on a low setting (this should automatically be selected if you use a woolen programme, but please check).
  • Do not tumble dry. Either line dry or place on an airer. Do not place on a hot radiator.
  • Do not dry clean
  • Regular ironing may be performed at a low setting (110°C, 230°F) only, but we advise against it.

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 help to reduce creases in the wash and if there are any afterwards, they often drop out when worn.

Unlike 100% woolen garments, these merino mid layers will melt or burn slightly if exposed to flame or direct heat due to the Lycra core content (plastic).  They are not flame resistant; do not use them near ANY direct source of heat or flame.
