Anti Shock Trekking Trail Poles for 3 joint. Aerospace-grade 7075 aluminum alloy provides strength comparable to steel, making our trekking poles incredibly durable. The poles are quickly adjusted from 65 cm to 135 cm using a single flick-lock, allowing them to be at the ideal length for whatever terrain you're on. The unique folding design packs down to less than 15 inches in length, making our poles easy to fit into a carry-on or small backpack. The ergonomic but firm EVA foam handle will absorb sweat and provide all-day comfort for both men and women. Each trekking pole comes in at less than 10 ounces, reducing arm fatigue and letting you get farther on the trail.
