The BDU field pants "Pioneer" with "2in1 Tec Zip System" functionality are made from a robust blend of cotton and polyester. The cotton provides a natural feel, while the synthetic material effectively wicks moisture away from the body. The fabric is very durable, quick-drying, wrinkle-resistant, and water-repellent, capable of withstanding more than just a brief summer rain. The zippers at the knee area allow for the lower pant legs to be detached, which can then be stored in the spacious cargo pockets. The thigh pockets and back pockets can be closed with buttons and are covered by a flap. The waist size is adjustable from the sides, and the fly features a concealed button placket. At the ends of the legs, there are drawstrings that allow for a tighter fit around the ankles. The material has a sun protection factor of 30+, making the pants suitable for use in warmer, sun-intensive regions. In the evening twilight, the pant legs can be zipped back on thanks to the practical "2in1 Tec Zip System," providing protection against insect bites. This flexible design eliminates the need to carry an additional pair of pants while ensuring you are always appropriately dressed.
