Take a break from the urban grind and set your sights on higher grounds. Rely on the lightweight and versatile Masters Active Trekking Poles to help you go farther and higher than you've been before. Lock the Active Trekking Poles into place with Masters' dependable Blocking System. This telescoping system gives you versatility for changing grades and easy out-of-the-way storage. These lightweight Masters poles provide extra stability and efficiency compared to hiking with a single staff, and that gives you the strength to push yourself to new heights and further exploration. The comfort straps add leverage with each push and keep your poles from clanking down the hillside if you lose your grip.
