Exclusive AERGON grip features a hollow core construction to save weight and create an edgeless, rounded grip for comfortable gripping at all angles especially for "palming" on steeper terrain. Thermo foam grip material for extra comfort, light weight and insulation in colder weather. A built-in 8-degree Positive Angle in LEKI grips keeps wrist in neutral position and provides more efficient pole plants. Air-textured "no bulk" security strap maintains design dimensions of grip while providing efficient wicking and fast drying. LEKI's SPEEDLOCK 2 lever locking mechanism is simply the strongest external locking system found among trekking pole brands and models. LEKI's original Carbide Flextips provide secure hold on all terrain and surfaces for years of adventure. Covered by LEKI's 1-year shaft breakage warranty.
