Weighing in at just a mere 10 ounces, the Black Diamond Distance Carbon wins our Top Pick for Best Lightweight pole. Although it's not as robust or durable as the other lightweight tent-style poles in our review, such as the Leki Micro Vario Carbon (14.6 ounces), it surprised us with its durability, especially when you consider the weight. We think that they make excellent lightweight poles for on trail and cross-country use. They aren't adjustable but come in four sizes (100 cm, 110 cm, 120 cm, 130 cm) which are sufficient for a variety of hikers.
The Black Diamond Distance Z won our award for best value in a lightweight pole (these are $70 less, at a superb $100). They're a few ounces heavier than the Carbon Z and are similarly non-adjustable, coming in lengths from 100 to 130 cm. These could be an ideal pole to consider as an intro to trekking poles before diving in deep with an expensive (though excellent) product like the Distance Carbon Z.
