The NosiLife Pro Convertible Trousers from Craghoppers are made of elasticated polyamide, are light, dry quickly and protect up to the ankles from UV rays and insects. At least as long as you don't detach the trouser legs of the zip-off trousers, then the effect below the knees is significantly reduced. The insect-protecting NosiLife technology is woven into the fabric, so it doesn't wash out so quickly and reduces insect bites by up to 90 percent. In this way, diseases and infections (malaria, Zika virus, chikungunya, dengue, etc.) can be prevented. NosiLife is absolutely harmless to humans and all other mammals. The Pro Convertible Trouser has five bags, with or without trouser legs. Four of them have a zip and one protects your bank cards from revealing their information.
