Ozark Trail Trekking Poles are GREAT for every outdoor enthusiast. They are useful for hiking uphill, downhill and on flat terrain. Since they are very light weight, the poles won't slow you down on the trail. Instead, they'll improve your hiking endurance and allow you to reach new heights. This pair of adjustable trekking poles are made from durable aircraft grade aluminum so they are super lightweight, but durable with a "quick locking" mechanism for easy height adjustment.
