Baselayer
Washing instructions: Follow the washing instructions on the care label inside the garment. Do not use fabric softener as this will affect the moisture-wicking qualities of the fabric negatively. Always close zippers before washing. Garments with prints should be washed inside out to preserve the print longer.
Base layer with wool content
Wool is naturally soil-repellent and in many cases does not need to be washed nearly as often as you might think. You can use the garment several times before it is washed; just air out the garment and let it rest for a time between uses. It gives the wool fibers time to recover their natural strength and elasticity.
Washing instructions: Once you need to wash your wool-containing base layer, follow washing instructions for the base layer (above) but use detergent designated for wool material (preferably liquid); they have pH and active ingredients suited to wool.
