Trekking poles take pressure off your knees, aid balance, and make it possible to pitch some ultralight tents. Try these four pairs on for size.
Know your poles
There are three types of trekking poles. Here’s how they differ.
Fixed Length: The shaft is one piece. The lack of moving parts means a sturdier, lighter, and more durable product. Drawbacks: not adjustable, not packable.
Telescoping: These two- or three-piece poles collapse into themselves for storage. They have the greatest range of adjustability. Downside: heavier.
Folding: These poles divide into two or three parts, so are packable but also lightweight. Caveat: They’re more susceptible to damage at the joints.
