A good trekking pole can make a grueling hike seem like a stroll in the park. Enter the Leki Thermolite Aergon XL anti-shock trekking pole, which combines all of Leki's latest innovations with a lightweight design that's ideal for long, challenging trails. The Thermolite Aergon XL is made of high-grade aluminum, with small-diameter, thin-wall tubing that's treated with a proprietary heat tempering process. The result is a pole with unsurpassed strength and resiliency on the mountain. The pole is also remarkably versatile, with a height range (26.7 to 57 inches) that accommodates almost any user. And thanks to the award-winning Super Lock System, you can easily adjust the pole length without sacrificing the "hold" of the pole when locked in place.
As with all Leki trekking poles, the Thermolite Aergon XL also offers replaceable carbide flextips that work on almost any terrain and surface, along with automatic comfort straps that adjust without the use of a buckle for convenience and comfort. And hikers will love Leki's new grip shape and design, which incorporates a 15-degree positive angle directly into the grip for ergonomic hiking comfort. Other details include a Soft Antishock System Lite (SAS-L) internal suspension system that cushions the impact of each pole plant, and a foam grip extension on the upper shaft that helps you handle switchbacks and abrupt changes in terrain. Each Thermolite Aergon XL pole weighs only 17 ounces and includes a lifetime warranty on the shaft.
About LEKI
LEKI, the worlds leading manufacturer of ski, hiking and trekking poles, had its start in Kircheim, Germany as a hobby of its founder, Karl Lenhart, an airframe mechanic and avid skier. Lenhart believed aluminum would make a superior ski pole compared to the heavy steel models available in the late 1940s. After successfully creating lightweight poles for his friends, in 1954, the hobby became a full time business. LEKI originated the use of nylon webbing for straps and created plastic molded grips and baskets in place of metal and leather. Additionally, Lenhart developed an aluminum tempering process that produces pole shaft with incomparable strength, durability, and reliability.
In 1984, Klaus Lenhart, Karls son, assumed leadership and shortly there after developed the first dual-component grip. He is also responsible for improving adjustable pole-locking technology and grip innovations such as the Trigger Click-In system and COR-TEC, a material made of real cork and latex. As the ski market continued to flourish, LEKI began manufacturing hiking poles primarily for European mountain guides. The concept of using two poles as means of relieving stress on knee joints and the lower back appealed to climbers who also saw benefits in performance and safety. LEKI poles eventually caught on with the general hiking and trekking population that recognized and appreciated the preventive health benefits as well as the climbing support and stabilizing effects. In 1990, LEKI USA was incorporated. The North American market has embraced the companys line of alpine, Nordic, back country, mountaineering, Nordic walking, and trekking poles.
