Maintaining functional clothing, shoes and boots - Washing and waterproofing!
Functional clothing, whether it's underwear, insulating mid-layers or weather- and wind-protective outerwear, often lives a tough life in the active outdoors, being exposed to both this and that but expected to perform when it's really needed. To get the most out of your garment, you need to give it some care. In addition to ensuring the intended function, you also extend the life of your favorite garment. Dirt, sweat, skin oils and wear and tear will eventually cause your garment to not function optimally. Salts and microorganisms from sweat and skin oils can cause unwanted bacterial growth with smelly results, especially in synthetic underwear such as polyester, acrylic and polypropylene. Outer garments can also be damaged and delamination can occur due to bacterial growth in the fabric where the bacteria "eat" the glue that holds the outer fabric together with a membrane.
An important part of this is regular washing in the right way and with the right detergent.
