The Trekology Trek-Z trekking poles come as a set of two, made from aircraft grade aluminum with metal caps reinforcing the joints. The cork grip wicks sweat and the EVA foam section below it gives a secure hold. A tri-fold design collapses each pole to 15 inches (38 cm) to fit in a backpack or suitcase, and a metal flip lock adjusts the length over a 20 cm range, from 110 to 130 cm.
