The Trail trousers are made from 87% polyester and 13% elastane. This makes the fabric stretchy and quicker-drying than most others. The trousers have a built-in Tanatex® insect repellent to keep warm-climate pests, such as flies, mosquitoes and ticks, at bay. In addition to two slanted front pockets, there are two large, zipped pockets on the thighs.
